SP-3800AA is an Atomic Absorption Spectrophotometer with many domestic and international
advance 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 hallow cathode lamps self-absorption
back ground correction possible without and influence to instrument's stability. Meanwhile, it will
prolong working life of the lamp. The cost of normal hallow cathode lamp is only about one-tenth
of 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 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.
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 affect background correction Low cost and easy to popularization and

2. application.
4. Our Sp-3800 series break many technology bottle neck.
Background correction ability:1Abs>100times Ahead at our market
2Abs>80times Ahead in international market
Created "multiple linearity 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 referance beam narrow pulse). Transmission/Absorption in wide linear range and
dynamic balance.
Satisfied the requirement of high performance self-absorbtion 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 hallow cathode and D-lamp beam through different wavelength in best condition.
Hallow cathode lamp and D-lamp Beam optical balance technology realized D-lamp background
correction extended application rang of D-lamp background correction. It also realized high ability
of background correction.
