FAQs

1. What role does the atomic absorption spectrophotometer's deuterium lamp serve in background correction?

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

2. How much electricity does the atomic absorption spectrophotometer consume to run?

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.

3. How does the atomic absorption spectrophotometer differ in terms of parameters, particularly spectral bandwidth?

atomic absorption spectrophotometer 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.

4. What is an Atomic Absorption Spectrophotometer?

An analytical tool called an Atomic Absorption Spectrophotometer () uses the light that each element's atom absorbs to determine the concentration of that element in a sample.

5. What lies behind atomic absorption spectrophotometry's concept?

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.

6. What are the different components of an Atomic Absorption Spectrophotometer?

The components include an atomizer (commonly used atomizers are Flame atomizers and Electro thermal atomizers), a Radiation source, and a spectrophotometer.

7. What role does the hollow cathode lamp play in an atomic absorption spectrophotometer's operation?

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.

8. What are the main characteristics of your Atomic Absorption Spectrophotometers?

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.
