Атомно-абсорбционный спектрофотометр

Indrouction Atomic Absorption Spectrophotometer SP-3800 Series is an Atomic Absorption Spectrophotometer with many domestic and international advance technologies Intelligent Straylight measure and correction technology(patent). We developed PC information processing technology, Automatic measurement and straylight dynamic deducted without any reverence materials and increment cost. It improved instrument's optical precision,linear range and background correction effectively. Original Optical Noice RoductionWe developed optical noise reduction technology, which combined opt i cal component UV enhancement technology. It improved instrument's optical performance,linear range and enhanced background correction.Interval lamp control (patent)We developed interal lamp control technology. It makes normal hallow cathode lamps self-absorption back ground correction possible without and influence to instrument's stablity. Meanwhile, it will prolong working like of the lamp. The cost of normal hallow cathode lamp is only about one-tenth of special lamp. Original "Hg lamp-reagent" gradient measurementWe developed "Hg lamp-reagent" gradient measurement technology. 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.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.
