Atomic Absorption Spectrophotometer Model-LI-5310
Lasany presents a wide range of Quality Equipment required in day-to-day function of a Chemical Laboratory to Advanced Instruments used for Quality Assurance/Control and Research. Our Atomic Absorption Spectrophotometer offers a State-of-the-art technology bundled with many features as a complete economical package.
SALIENT FEATURES
- Advance technology for intelligent stray light measure and correction
- 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
- 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
- Original ''Hg lamp-regent'' gradient measurement. we established an exact mathematical model to estimate “single 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 design aesthetics, element lamp multi dimensional automatic adjustment system, gas path electronics functional and modular design, No-adjustment D-lamp holder and so on.
OPTIONS:
- Graphite Furnace
- Auto-Sampler for Graphite Furnace
- Hydride Generator
- Wide range of Hollow-Cathode Lamps(Single/Multi Element)
