Intelligent stray light measurement and correction technology

Computer information processing technology has made significant breakthroughs in reducing stray light in spectrometers by automatically measuring and dynamically subtracting stray light without the need for any reference materials or increasing hardware costs. Effectively improved the optical accuracy and linear range of the atomic absorption spectrometer, and enhanced the background correction ability.

Optical noise reduction technology

SP-AA 4000 flame atomic absorption spectrophotometer adopts optical noise reduction technology, combined with optical element ultraviolet enhancement technology, effectively improving the instrument's optical performance and linear range, and enhancing the background correction ability.

Gap control light technology

Self suction background correction has very strict requirements for lamps and high costs. Shanghai Spectral Gap Control Lamp Technology makes it possible for ordinary hollow cathode lamps to be used for self suction background correction without affecting stability, extending the lifespan of the lamp by more than ten times, while the cost is only one tenth of that of specialized lamps.

"Mercury lamp reagent" gradient measurement technology

The "mercury lamp reagent" gradient measurement technology was proposed, and an accurate mathematical model was established using information processing technology to evaluate the "dual channel linearity and balance" performance. This provides a fast and economical method for instrument system self inspection, and also establishes a new method to improve the detection performance of the instrument.

The multi-dimensional automatic adjustment system for elemental lamps, modular design of air circuits, electronic and electrical functions, and numerous technological innovations and innovations such as non adjustable tritium lamp brackets, etc.
