China Atomic Absorption Spectrophotometer

Atomic Absorption Spectrophotometer (AAS) AMT3800 Serials
Features
1. Advance technologies intelligent stray light measure and correction technology
2. Automatic measurement and stray light dynamic detected without any reference materials and increment cost. It improved instrument's optical precision. Linear range and background correction effectively.
3. Original Optical Noise Reduction, it improved instrument's optical performance, linear range and enhanced background correction.
4. Developed interval lamp control technology. It makes normal hallow cathode lamps self-absorption background correction possible without and influence to instrument's stability. Meanwhile it will prolonged working like of the lamp. The cost of normal hallow cathode lamp is only about 1/10 of special lamp.
4. Original "Hg lamp-reagent" gradient measurement. We established an exact mathematical model to estimate "double beam linear and balance" specification. This technology provided a fast and economic method for instrument self testing system. It also established a brand new method to improve instrument's detection performance.
5. Numerous technological innovation and renewal such as fashion design, element lamp multi-dimensional automatic adjustment system, gas path electronics functional and modular design, No-adjustment D-lamp holder and so on.
