Product Details

Product Introduction

The AA3581 atomic absorption spectrophotometer has stable analysis accuracy and a user-friendly design to meet the needs of different customers. And according to different analysis needs, graphite furnace control, automatic sampler, hydride generator, etc. can be selected.

Performance Characteristics.PERFORMANCE CHARACTERISTICS

●Four or six light positions are optional: automatic 3D switching, energy balance, simultaneous preheating of multiple light positions to save waiting time, deuterium lamp clip background and stable performance element lamp can be selected.

● Automatic instrument settings: The instrument has an automatic memory function and can complete peak scanning with just one click.

Multi format saving and printing of data reports: convenient for data query and comparison.

Software design makes operation simple: The instrument software adopts a single interface multifunctional window design, real-time monitoring of data changes, supports mainstream Windows operating systems, supports remote control and calibration, and Chinese/English versions are optional.

Multiple protection system: Automatic alarm will be triggered in case of abnormal conditions such as insufficient pressure, air leakage, and engine shutdown.
