Atomic Absorption

Atomic absorption (AA) spectroscopy equipment, a vital subset of spectroscopy, quantifies elements in a sample by measuring the absorbed light of specific wavelengths. This technique relies on the principle that each element absorbs light at a unique wavelength. AA instruments, including flame and graphite furnace AA spectrometers from manufacturers like PerkinElmer, Agilent, and Thermo Fisher Scientific, offer precise elemental analysis for various matrices. These instruments typically involve a light source, atomizer, monochromator, and detector working in concert to measure absorbance. Atomic absorption supports workflows in environmental monitoring, food analysis, and pharmaceutical quality control, providing crucial data for sample composition. Common applications of AA spectroscopy include trace metal analysis in water, determining heavy metal content in... + More

Atomic absorption supports workflows in environmental monitoring, food analysis, and pharmaceutical quality control, providing crucial data for sample composition. Common applications of AA spectroscopy include trace metal analysis in water, determining heavy metal content in food products, and analyzing the purity of pharmaceuticals. It is often used in conjunction with other analytical techniques such as chromatography and various sample preparation methods to ensure accurate and reliable results. Advanced AA systems offer features like automated samplers, background correction, and sophisticated software for data analysis, enhancing throughput and minimizing errors in demanding laboratory settings. ALT offers a selection of pre-owned and refurbished atomic absorption spectrometers, each backed by a standard 90-day warranty that can be upgraded to a three-year warranty, along with ALT's lifetime support. Because they're refurbished, atomic absorption spectrometers from ALT are typically priced 50%-80% lower than the cost of new instruments, helping labs stretch their budget further without compromising on quality. - Less
