Atomic Absorption Spectrophotometer LAAS-A22 FAQ's

  • Our LAAS-A22’s deuterium light is specifically included in the system for background correction, which ensures reliable analytical findings by removing molecular absorption interference.

  • Our LAAS-A22 operates at a frequency of 60/50 Hz and needs a power source of 110/220 V with a tolerance of +5% to -10%. The product requires 5000 VA of electricity.

  • Our atomic absorption spectrophotometer LAAS-A22 offers greater versatility and precision in spectral analysis with its automated spectrum bandwidth of 0.1, 0.2, 0.4,1.0, and 2.0 nm.

  • 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.
