Atomic Absorption Spectrophotometer 190-900nm Laboratory For Metal Element Analysis

Model: LTL-5800

Main Features

♦ On the basis of 7800 AAS, considering commonly used functions, selectively keep some functions, highly cost effective.

♦ The instrument has good stability, wide measurement range, low detection limit, high resolution and high sensitivity

♦ Unique optical design greatly increases the sensitivity in visible range. The outstanding mechanical and optical system plus excellent software ensure measurement accuracy

♦ Rapid change of gas flow, grating rotation, slit and hollow cathode lamps

♦ Widely used in rare earth analysis, precious metal analysis, environmental protection, water quality inspection, alloy materials, construction materials, medicine and health, colleges and universities for quantitative analysis of elements

♦ Practical structure, simple operation, easy to master

♦ Fully satisfy the users who require flame analysis only

♦ Optional nitrous oxide is available. It expands measurement range and meets the demands from different areas.
