Product Details
Computerized Atomic absorption spectrophotometer
Applications
It is widely used in the analysis of metal elements in opaque substances in the fields of material science, life science, space technology, etc. It can also be used in the detection of food, medicine, drinking water, environmental samples, and the detection of trace heavy metal elements in the natural environment.
All functions of 4520A atomic absorption spectrophotometer are controlled and operated by PC, and flame and graphite furnace can be flexibly selected. Unique optomechanical design, safe and convenient flame system, advanced graphite furnace temperature control technology, optional background subtraction technology, and various convenient functions provided by the workstation are suitable for your pursuit of precise measurement automation.
