Description
Specification & Features :
Advance technology for intelligent stray light measure and correction.
- Original Optical Noise Reduction & Automatic measurement and stray light dynamic detected without any reference materials and incremental cost. It improves instrument’s optical performance, optical precision, linear range and background correction effectively.
- Develop internal lamp control technology. It makes normal hallow cathode lamps self- absorption background correction possible without and influence to instrument’s stability. Meanwhile it will prolong working life of the lamps. Normal hallow cathode lamps are highly economical than special lamps.
- Original ”Hg lamp-regent” gradient measurement. We established an exact mathematical model to estimate “single 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.
- Numerous technological innovation and renewal such as design aesthetics, element lamp multi dimensional automatic adjustment system, gas path electronics functional and modular design, No- adjustment D-lamp holder and so on.
Options :
- Graphite Furnace
- Auto-Sampler for Graphite Furnace
- Hydride Generator
- Wide range of Hollow-Cathode Lamps(Single/Multi Element)
