Spectrometer Atomic Absorption

Description

Specification & Features :

Advance technology for intelligent stray light measure and   correction.

  1. 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.
  2. 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.
  3. Original ”Hg lamp-regent” gradient measurement. We established an exact mathematical   model to estimate “single beam linear and balance “specification.
  4. 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 design aesthetics,    element lamp     multi   dimensional automatic adjustment system, gas path  electronics functional and   modular design, No-  adjustment D-lamp holder and so  on.
