Features:
1. Build-in computer data processing and LCD display.
2. Stability: Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature and electronic circuit drift.
3. Quickly: The cathode lamp does not need to be pre-heated for long time and sample can be analyzed immediately.
4. High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.
6. High energy optical path.
7. Long-life and anti-corrosive atomization system.
8. Multi-functional analysis mode: ?flame absorption?flame emission? graphite furnace atomic absorption hydride generation.
9. Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame as well as nitrous oxide-acetylene flame and extend the analytic elements to reach more than 60.
Basic Functions:
1.Photometry
Test Abs., Transmittance and Energy by fixed wavelength
2. Quantitative
Linear fit and Linear fit through zero two modes
a. Coefficient, Standard Sample input and Standard Sample read three modes to establish standard curve
b. Establish A=K1*C+K0, can search original data, graph curve, parameters settings
c. Can save 240 group curves, can test 240 data in each curve
d. Double wavelength, Triple wavelength test functions
3.Kinetics
Used for time course scanning or reaction rate calculations△A/t, can search all data.
4.Multi-Wavelength
Can test Transmittance and Abs. with 8 different wavelengths at most
5.Scanning
User can set the scan range from 190nm to 1100nm to test the max. Abs. peak value, can do derivation, arithmetical operationsto the graph.
6.Biology
6 methods: DNA/Protein, UV, Lowry, BCA,CBB and Biuret
