Instrument Introduction
The perfect 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 thousands of laboratory experiments, has a very high cost performance ratio.
Can be used in conjunction with flame atomic absorption spectrometer for high concentrationppmFrom grade to trace levelppt All levels can be analyzed; Atomizers do not require switching, greatly simplifying operations.
Main Features
■6-8Lighthouse, and can preheat multiple lamps simultaneously;
■ 85Automatic sampler;
■Maximum heating rate 3000℃/sThe 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.
Graphite furnace visualization system
■The first and unique multimedia graphite furnace visualization system in China can intuitively monitor the dynamic evolution of the sample solution during the drying, ashing, and burning processes inside the graphite tube. It is convenient to observe the optimal position and depth of the automatic sampler capillary injection needle entering the graphite tube, as well as the position of the platform inserted into the graphite tube, ensuring analysis accuracy and the lifespan of the graphite tube. It is also a perfect training tool.
