SP-3800AA Atomic Absorption Spectrophotometer

Transcription

1 SP-3800AA Atomic Absorption Spectrophotometer SP-3800AA series Atomic Absorption Spectrophotometer SP-3800AA is an Atomic Absorption Spectrophotometer with many domestic and international advanced technologies Intelligent Stray light measure and correction technology (patent). We developed PC information processing technology; Automatic measurement and stray light dynamic detected without any regent materials and increment cost. It improved instrument s optical precision, linear range, and background correction effectively. Original Optical Noise Reduction: We developed optical noise reduction technology, which combined optical component UV enhancement technology.it improved instrument s optical performance, linear range, and enhanced background correction. Interval lamp control (patent) We use integrated lamp control technology. It makes normal hollow cathode lamps selfabsorption background correction possible without and influence to instrument s stability. Meanwhile, it will prolong working life of the lamp. The cost of normal hollow cathode lamp is only about one-tenth of the special lamp. Original Hg lamp-reagent gradient measurement: We 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 economical 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-

2 dimensional automatic adjustment system, gas path electronics functional and modular design No-adjustment D-lamp holder and so on. Product model: SP-3800 series atomic absorption spectrophotometer SP-3801 Flame AAS SP-3802 Graphite Furnace AAS. SP-3803 Flame&Graphite Furnace AAS. Feature: 1. Self-absorption background Correction. 2. Comparison sheet of common background correction methods. 3. Advantage of High-performance self-absorption background correction Compete with Zeeman effect background correction Low cost and easy to popularization and application. 4. Our Sp-3800 series break many technology bottlenecks. Background correction ability:1abs>100times Ahead at our market 2Abs>80times Ahead in international market Created multiple linearities and balance technique adopted hardware and software combined method. Solved many problems such as self-absorption background correction. dual signal (sample beam wide pulse and reference beam narrow pulse). Transmission/Absorption in wide linear range and dynamic balance. Satisfied the requirement of high-performance self-absorption background correction. * Graphite furnace self-absorption background correction: depletion to hallow cathode lamp reduced to 1/10 of continuous lamp lighting. * Avoid depletion to hallow cathode lamp while the graphite furnace doesn t test. Excellent self-absorption and D-lamp background correction ability. Correct molecular absorption and particle scattering background. Correct structure background and some spectral overlap. These technologies are appropriate to test trace elements in food, seawater, blood, biological high-salt solution. Especially in the analysis of Cd, Pb, Cu, Zn. And the high-cost performance of sp-3800 series if very suitable for worldwide market. The Main Features: Excellent D-lamp Background Correction Technology. Unique reflection optical system. Unique reflection optical system keeps the light transmission unique. And it makes different elements and hollow cathode and D-lamp beam through different wavelength in the best condition. Hollow cathode lamp and D-lamp Beam optical balance technology realized D-lamp background correction extended application range of D-lamp background correction. It also realized the high ability of background correction. Good optical performance.
