AA6810 Graphite Furnace Atomic Absorption Spectrometer

The combination of graphite furnace and automation technology has been achieved. The combination of graphite furnace and automatic sampler into one module solves the problems of automatic sampler adjustment and optical path correction during the switching process. This graphite furnace system, which has been tested by hundreds of laboratory experiments, has a very high cost performance ratio.

Graphite furnace atomic absorption spectrometerIt can be used in conjunction with flame science instruments to analyze concentrations ranging from high ppm to trace ppt levels; Atomizers do not require switching, greatly simplifying operations.

Main features:

6 lighthouses, and multiple lights can be preheated simultaneously;

45 bit or 85 bit automatic sampler;

The maximum heating rate is 3000 ℃/s;

The working temperature of graphite furnace is room temperature -3000 ℃;

Small size, fully automatic process control;

Self absorbing buckle background, deuterium lamp buckle background.

Gas control:

By controlling the gas inside and outside the tube separately, ventilation is maintained outside the tube during the analysis process, and the gas inside the tube is stopped during the atomization stage, effectively protecting the graphite tube and maximizing its lifespan while achieving high analytical sensitivity.

Security:

Alarm for insufficient gas pressure and automatic stop of temperature rise;

Alarm for insufficient cooling water and automatic stop of heating up;

Overheating alarm and automatic stop of temperature rise.

Temperature control technology for graphite furnace

The introduction of PID technology effectively overcomes the impact of voltage fluctuations on temperature, enabling accurate control of every stage of the temperature control process. Changes in external power supply have almost no effect on sensitivity and repeatability, and the measurement data has good repeatability.
