Atomic Absorption Spectrophotometer Model-LI-5310

LI-5310-p

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

  1. Advance technology for intelligent stray light measure and correction
  2. 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
  3. 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
  4. 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
  5. economic method for instrument self testing system. It also established a brand new method to improve instrument's detection Performance.
  6. 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:

  1. Graphite Furnace
  2. Auto-Sampler for Graphite Furnace
  3. Hydride Generator
  4. Wide range of Hollow-Cathode Lamps(Single/Multi Element)
