5800 Atomic Absorption Spectrophotometer

 

 

5800 Atomic Absorption Spectrophotometer is a modified model based on 7800. It is an economical flame atomic absorption spectrophotometer with high performance, easy operation, accurate measurement and stable functions. It meets the requirement of limited budget and is well received by vast number of users.

 

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.
