Our LAAS-A21 can accommodate varied customer requests for different kinds of elemental testing because it has a built-in flame, graphite furnace, and hydride generating system.
Yes, our LAAS-A21 can automatically switch between flame and graphite furnace operating modes, providing flexibility and convenience for different types of analysis.
Our LAAS-A21 is equipped with an automatic gas control system, which precisely regulates gas flows required for various types of analysis. This system ensures accuracy and safety by automatically adjusting gas parameters according to the selected analysis mode, guaranteeing optimal conditions for reliable results.
An analytical tool called an Atomic Absorption Spectrophotometer (AAS) uses the light that each element's atom absorbs to determine the concentration of that element in a sample.
The basis of spectrophotometry is the light uptake by unbound atoms in a gaseous state. An excited state is created when atoms in the ground state absorb light energy at particular wavelengths. Analyte content in the sample can be calculated by determining the amount of light consumed.
The components include an atomizer (commonly used atomizers are Flame atomizers and Electro thermal atomizers), a Radiation source, and a spectrophotometer.
The hollow cathode lamp in atomic absorption spectrophotometer emits distinctive light at particular wavelengths that match the target analyte. This guarantees that the analyte atoms are excited selectively, resulting in exact and reliable readings.
Labtron’s Atomic Absorption Spectrophotometers boast flexible atomization technologies, accurate optical systems, a titanium combustion head, and a polymer explosion-proof spray chamber. These elements guarantee accurate and effective trace element analysis, along with improved safety and longevity.
