Atomic Absorption Spectrophotometer LAAS-A23 FAQ's
  • Our LAAS-A23 microcomputer-controlled system ensures great efficiency and accuracy in sample analysis by providing automatic ignition mode, vertical heating mode in the graphite furnace analytical system, and a full titanium ignition head.

  • Our LAAS-A23 Atomic Absorption Spectrophotometer is a flexible and essential instrument for metal analysis in a variety of fluid samples, with broad applications in industries like food, petroleum, chemicals, pharmaceuticals, etc.

  • To ensure reliable and even performance, our LAAS-A23 may be powered by 110/220 V (+5% to -10%), 60/50 Hz, and has an electrical capacity of 5000 VA. It is compatible with a range of electric sources.

  • 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.
