It is truly amazing how this machine is operated. First, scientists put the material they want to study, such as that soil sample, into the machine. Then, they shine a bright light onto the material. The atomic absorption spectroscopy equipment determines how much of that light is absorbed, or soaked up, by the material. This process tells scientists valuable information about what elements are contained in the sample and how much of each element there is. It is like magic but it really is science!
A specialized field of science called analytical chemistry is where scientists use atomic absorbance spectrophotometers. You read that right: scientists use these machines to study how chemical reactions take place and how molecules of different substances interact with each other. For example, this tool can be used if a scientist is working on creating a new medicine; They can use this tool to see what elements make up the different ingredients of the medicine.
This is important because it helps scientists ensure they are using the proper ingredients. Knowing exactly what’s in the medicine means they can be confident it will work as it should to help patients. This machine can also help scientists determine if there are any nasty impurities in the medicine that would make someone sick.
A scientist must first calibrate the machine to begin using it. This means they verify that the machine is measuring things correctly. It’s kind of like calibrating a scale before weighing yourself on it. Once the machine is calibrated, the next step that scientist takes is to put the sample material that he/she wants to study inside the machine. And then the machine does all the heavy lifting to get them their results.
What one extremely great thing about atomic absorbance spectrophotometry is that its a very accurate technique. This means scientists can accurately measure miniscule quantities of elements. This is very significant, especially when they are trying to detect impurities in a sample or they are using materials that are extremely expensive and they don’t want to lose.
There are some disadvantages to this method as well. Atomic absorbance spectrophotometry, for example, will tell scientists which elements are in a given sample, but say nothing of the structure of those materials. But the machine can only tell you what elements are present in the sample; it doesn’t explain how those elements are arranged or interconnected.
With the ongoing development of the technology, atomic absorbance spectrophotometry will become increasingly critical in sectors ranging from biomedical research to the pharmaceutical industry. With these machines, scientists will be able to derive better medicines that will not only work more but will also have minimal negative effects. Less negative reactions mean patients can receive the help they need.
