I. Product Introduction

The flame-graphite furnace combined atomic absorption spectrophotometer offers high analysis precision and a thoughtful humanized design, fully meeting the various specific needs of different customers. An autosampler, hydride generator, etc. can be optionally configured according to different analysis needs.

II. Application Fields

It can be widely used in geology, metallurgy, medicine, chemical industry, petroleum, agriculture, environmental protection, commodity inspection and other industries. For the analysis of trace and ultra-trace elements, in recent years it has gradually expanded from inorganic chemistry to organic chemistry.

III. Performance Features

1. Four, six or eight lamp positions selectable (high-performance element lamps optional); automatic three-dimensional switching, energy balancing, simultaneous preheating of multiple lamp positions to save waiting time; with deuterium lamp background correction and self-absorption background correction functions.

2. Unique integrated design of flame atomizer and graphite furnace atomizer, realizing dual modes of automatic switching and manual switching.

3. Instrument setting conditions automatic optimization and memory function; one-key completion of scanning peak finding and energy balancing.

4. Data report multi-format saving and printing output for convenient data query and comparison.

5. The instrument software adopts a single-interface multi-functional window design, making operation simpler, real-time monitoring of data changes, support for mainstream Windows operating systems, support for remote control and calibration, Chinese/English versions optional, and comprehensive quality control (QC) functions.

6. Advanced and reliable multiple safety protection system, automatically detecting and alarming on abnormal conditions such as insufficient pressure, gas leakage and flameout.

7. Expandable: hydride system and coupling functions.
