For their experiments, research institutions and laboratories use a variety of chemical substances and processes. Determining the optimal dosage of chemicals employed in the research process can be a difficult undertaking. They identify specific components and compounds in the sample using various analytical tools and techniques. Many individuals use atomic absorption spectroscopy basics, a quantitative spectro-analytical method that uses the process of optical radiation absorption through free atoms in the gas state to determine the chemical elements. It’s a technique that many biochemists and researchers employ for their researches and experiments to get accurate results.
Applications of AAS and its types
- It is a general technique useful for detecting the metalloids and metals in the sample. They can analyze over 62 elements and are also useful for measuring the level of concentration in the metals that are taken as a sample. This technique is so simple and reliable to use.
- This spectroscopy technique quantifies the atoms in the ground state to a gaseous state. It uses the principle that free atoms or gas produced in the atomizer can absorb the radiation at a specific level of frequency. The atoms in it can absorb visible light or ultraviolet light and it transitions to higher electronic energy levels. The concentration of analyte is mainly determined based on the amount or level of absorption.
- They are highly inexpensive and safe to use and contains high precision and sample throughput. The atomic absorption spectroscopy applies in different areas like food and beverage, pharmaceutical, and chemical sectors to monitor the contaminants and impurities and is also used in the quality checks, environmental sciences, in the rapid assessment of different raw materials. They are also used in the clinical areas for analyzing biological fluids like urine and blood.
- The AAS technique determines the concentration of metal atoms by using the light absorption technique and they will vaporize the metals or samples by using two different AAS methods. The two types of AAS techniques are Flame atomic absorption spectroscopy (FAAS) and Graphic atomic absorption spectroscopy (GAAS).
- The FAAS technique is useful in the concentration of metal elements between parts per billion (ppb) or parts per million (ppm). In this process, it converts the metal ion samples into a fine spray using high-temperature flames. People use the GAAS method in low-volume samples to identify metals at very low concentrations of less than 1 ppb.
Mass spectrometry, electrochemistry, gas chromatography, tissue culture and cell, molecular biology, microbiology, and other applications employ this technology. This spectroscopy is easily available in all laboratory stores and online stores. They are highly cost affordable and available at a low price value. You must know the atomic absorption spectroscopy basics and benefits before the purchase and usage.
