What is an Atomic Absorption Spectrophotometer?




What is an Atomic Absorption Spectrophotometer?

In order to understand the principle and the function of an Atomic Absorption Spectrophotometer, it is imperative here to understand what “Atomic Absorption Spectroscopy” deals with. It is the study that is used to scrutinize the samples of metal. This is carried out by evaluating the existence and concentration of the “Metal” in a liquefied sample. While the “Metals Group” includes Fe, Cu, Al, Pb, Ca, Zn, Cd, and several other metals, when these metals are excited by heat in their elemental form, they absorb the ultraviolet radiations. One metal is made to absorb the gaseous emissions; they respond to it in a unique way that makes it easier to distinguish their characteristics. While they are being treated, every metal will absorb a specific wavelength that will, in turn, help in identifying their characteristics.


How Does an Atomic Absorption Spectrophotometer Works?

While an Atomic Absorption Spectrophotometer is a device that is used to carry out the Atomic Absorption Spectroscopy, the principle by which it works is centered around focusing the ray of ultraviolet (UV) light on to the metal sample. It is practically performed by focusing a specified wavelength over the metal being tested. The ultraviolet beam of light is focused through a “Flame,” directly into the “Detector.” The liquid sample of the metal is “Atomized” into a vaporous state and is then enunciated into the flame. As it is understood that when the metals are in their elemental form, they will absorb the Ultraviolet Light upon being excited by the flash. While every mineral has a tendency to consume a specific characteristic wavelength, the absorption rate is what helps in determining the characteristic of the metal being treated for. The detector in the Atomic Absorption Spectrophotometer calculates the variation in the strength of the Ultraviolet light. The change that is measured is then fed into the computer, which in turn, converts the changes measured in the intensity of the beam, determining the concentration for the element being treated for!


What are the Applications of an Atomic Absorption Spectrophotometer?

While an Atomic Absorption Spectrophotometer might appear to serve one purpose only, there can be a list of various typical and industrial applications for this device. Hence, focusing on the purpose and the applications it is used for, following are few of the examples that employe an Atomic Absorption Spectrophotometer:

  1. Measuring the concentration of various elements in the finished products like,
    •  Petrochemical: Used to find traces for Impurities present in the gasoline, like Fe, Mn, or Pb
    • Manufacturing Industry (Metallurgy): Finding the concentration of the Alloying Elements like Ag, Au, Ca, Cu, Fe, Ni, Pb, Zn, etc.
  1. Measuring the content of Toxic Metals that may be present in the products to be used by humans or animals like,
    • Medicinal Purposes: To help to find the traces of Cd, Pb, Ca, Fe, Zn
    • Pharmaceuticals: To find the dashes of Cr, Pb, As, Cd, Cu, Hg
    • Food Products: To find any traces of Pb, Cd, Cr, Co, Cu, Fe, Ge, Mg, Mn, Na, Ni, Sb, Sn, or Zn
    • Water Treatment: To find the traces of Cd, Cu, Fe, Pb, Zn
    • Animal Feed: To look out for the traces of Ca, Cu, Fe, K, Mg, Mn, Zn, Cd, Co, Cr, Pb


  1. Also used to measure the Metal content in soil samples for agricultural purposes and other purposes like Geological or Mining like, Ag, Au, Ca, Cu, Fe, Ni, Pb, Zn, etc.


What are the Features of an Atomic Absorption Spectrophotometer?

While an Atomic Absorption Spectrophotometer’s Price may vary depending on the company producing it and the list of features it has in store. But considering the Atomic Absorption Spectrophotometers made at Moyer Instruments, following are the list of brilliant features you are destined to find nowhere else:



There are 3 flame options provided:

  • Air/Acetylene: It uses 100mm single slot burner. The flame can be quickly set from “Blue Lean” to “Fuel Rich.”
  • N20/Acetylene: It uses 50mm single slot burner. It allows measuring elements which are less disposed to “Ionization” like, Aluminum, Tin, Titanium, Calcium, Vanadium, and Molybdenum.
  • Air/LPG: It uses 3 slots burner that has low-pressure requirements. It is much safer to use.


SAFETY FEATURES: Flame Automiser monitors Pressure for all gases. Includes “Burner Identification Flame Sensor,” “Drain Trap level Sensor,” “Gas Leak Detector,” and “Cut off Switch for Over Pressure in Premix” are added for additional safety.




The preeminent “Graphite Furnace Atomiser” is integrated and is offered in two configurations.

  • A3G,” being the first configuration, has the “Graphite Furnace Head” which is fixed to the light path, offering accurate alignment with the optical path.
  • In the “A3FG” configuration, the “Graphite Furnace Head” is placed static prior to the flame atomizer.


SAFETY FEATURES: Comes with “Acetylene Pressure Monitoring,” which is included for all the gases. Additionally, “Burner Identification Flame Sensor”, “Drain Trap level Sensor”, “Gas Leak Detector”, “Cut off Switch for Over Pressure in Premix”, Argon Gas Pressure Sensor”, “Water Flow Sensor”, “Over Temperature Sensor”, and “Broken Graphite Tube Protection” is added for better safety!

Google Play Store: How to solve typical problems




Google Play Store: How to solve typical problems

The Google Play Store is the most important way for most Android users to find new apps, games, and updates – alas if they strike! We’ll show you how to solve typical Google Play Store issues.

Without the Google Play Store, an Android phone is not fun. Finally, the Play Store offers the largest app offering and is convenient on top of that. But he can also be bitchy: Sometimes downloads get stuck, another time the play-store app shows only a white page or it does not even start. Sometimes it just throws around with cryptic error messages like “DF-DLA-15” or “RPC: S-3”. With the right handles, most problems can be solved quickly.

Step 1: Is it Google?

It can be a simple Google malfunction that temporarily puts the Play Store out of action. If that’s the case then you have bad cards and just have to wait for Google to fix the problem. With the help of the website allestö you can quickly find out if there is a problem with Google. The Google Play team is also tweeting – also a source for up-to-date info on the status of the service.

Step 2: Smartphone triathlon

Google Play Store is also just a normal app on your phone. As such, it is plagued by typical app issues that can be solved with the typical smartphone triathlon (quit the app, turn flight mode on and off and reboot phone):

  1. Quit the Play Store from the Task Manager. Under Android 9, it appears if you pull the bar at the bottom of the screen far enough up. Then just swipe the app away from the list and start over. Older android has its square button on the lower edge of the screen for Task Manager. Depending on the manufacturer, the function may also be concealed in another location.
  2. There may be a problem with the internet connection behind the play store error. Many of these problems can be resolved by turning Airplane Mode on and off again. Try it alternately times only with the mobile Internet or just Wi-Fi. Sometimes it helps to restart the wireless router.
  3. Did not do anything, then try it again after rebooting your phone.

Step 3: House cleaning

Data from the Play Store app may be confused. As a result, the app is swallowed and causes problems. Delete the “Play Store Memory” to eliminate this source of error. It consists of two parts:

  1. Volatile data is stored in the cache. These include, for example, app icons, descriptive texts, user reviews, etc. that the Play Store displays when visiting. They can be deleted almost without consequences, at most, reloading the mobile data volume a little.
  2. Also, the Play Store stores information about your Google Account, which apps are installed on your device, pending updates, etc. If you delete this information, you will need to sign in to the Play Store. To do this, you’ll need the credentials for your Google Account.

To clear the cache and/or the data memory, open the Android settings. There, go to app settings (for example, apps and notifications in Android 9), reset the cache first, and see if the issue persists after that, and if that does not work, try clearing the cache again also the other information.

Step 4: Check system

The Google Play Store also ticks when Android is not in perfect condition. Check the following points:

  1. Are the date and time of your smartphone set correctly? If necessary, update the settings.
  2. Have you disabled apps in the past? Maybe you also got a critical function for the play store. Activate the corresponding apps again via the system settings.
  3. Is there enough free space on your device? It should be at least about 500 megabytes.
  4. Are you online via a VPN (Virtual Private Network)? The network administrator may have made settings that disable the Play Store. If possible, try it without this safeguard.

Step 5: Reset Account

Remove the Google Account you use the Play Store with. To do this, open the Settings, tap Accounts, then the Google Account. Android 9 (screenshot) will show a corresponding button to remove the account. In previous versions of Android, the delete function hides behind a button with three dots on it

Convertidor Mp3: Convert YouTube Videos to Mp3




Convertidor Mp3: Convert YouTube Videos to Mp3

Convertidor Mp3

You may need a better MP3 converter for YouTube. YouTube’s design is wonderful, with its safe, non-pronouncing alphabet, and layout that feels like reading from a traditional page of print, but its interface has become very complex. Some of the formatting tools don’t work at all. Some pages simply won’t open unless you use a specific application or online tool like, to convert YouTube to mp3.

It’s not just that YouTube is hard to use; it’s that YouTube has been designed as if it’s still 1999, where nothing ever changes. So if you’re expecting a brand new website where you can browse the vast and amazing resource that is YouTube, you will be disappointed.

In the future, YouTube might improve its own designs and try to add features that allow users to browse and make an album from their own videos. But as of now, the browser is a dinosaur and as user experience designers they’ve let the dinosaur run free in search of clicks. We want the YouTube to become more efficient and we want it to work properly.

There are a lot of things that could make YouTube easier to use. Google is an incredible company, having control over almost every aspect of internet use. Google should be able to build a better site that would be easier to use. A designer could take what they know about designing sites and apply it to YouTube, making it more appealing to visitors.

Youtube to mp3 converter

A good, fully featured MP3 convertidor for YouTube would integrate the major video websites, allowing users to browse YouTube from any website. As YouTube provides every major video website with its own small but useful blog engine, this would be a great feature to have.

A basic plug-in would also allow a user to navigate through videos in a way that would be much easier than clicking through each video one by one. They could browse through the videos and skip the ones they wanted to watch or skip to the next video if they wanted to do so.

The plug-in would allow the user to play back videos that he was currently watching and leave them to play on YouTube without having to stop and watch them again. It would let them start their favorite video from the beginning or start an ad-free edition of their favorite videos. The plug-in would let the user skip videos and adverts, or block ads by classifying them as spam. Many people hate the ads that pop up when they visit YouTube and a plug-in that worked the same way would make YouTube much friendlier.

Other websites would have their own unique functions. People might have their own blogs for information on games, science, politics, music, technology, and a whole host of other topics. It wouldn’t matter where you were browsing from, if you had your own blog that you could keep browsing through.

Some people might be interested in learning a new language or just for fun. The language feature would let a person learn any language at the same time as listening to and reading the language. If they enjoyed their lesson and wanted to continue, they could skip back to the beginning of the video and continue their lessons.

This would all be possible if the plug-in connected to YouTube used the standard audio format for video and used the audio track to download the audio files into the user’s computer. Then the software could load the files into the main window of the website and create the albums in real time.

Other sites would be about playing music on their blog pages. For example, a website would want to highlight its latest album, a band might want to highlight their album as the best one of their career, or a game developer might want to highlight the best game of their life and make sure everyone knows how lucky they are. They could pick out the best of the best songs and include it on a “best of” playlist.

With so many different functionalities, it would be easy to find something that could make life simpler for visitors. For designers, it could be a great way to show how well their website actually works.
