Multi functional high-precision graphite furnace automatic sampler. Due to the installation of this device in graphite furnace analysis, the analysis accuracy (RSD) is better than 1%. Automatic preparation of various solution concentrations and automatic addition of chemical improvers make analysis work more accurate and convenient, and greatly reduce tedious liquid preparation and sample preparation work. Truly achieve fully automated graphite furnace analysis without human supervision (personnel not present).

FEATURES
Up to 70 sample cups and 6 25ml glass cups for stock solution, blank solution, and chemical improver can be placed.
The screen display guides each step of the operation program, making it easy for you to set various functions.
Automatically create calibration curves. Automatically prepare up to 20 different concentrations of standards from a single standard solution and inject them directly into graphite tubes.
The automatic liquid extraction accuracy reaches 0.1 μ L, and the injection point inside the graphite tube remains unchanged, with an analysis accuracy of better than 1%.
The process from extracting each sample to extracting different standards and chemical improvers is fully automated under computer control.
The same sample can be analyzed up to 99 times. The maximum injection volume is 70 μ L.
After injecting all the solution, the graphite furnace heating program will automatically start.
After each injection, the system immediately enters the automatic cleaning program, solving the problem of sample contamination.
Automatic concentration and dilution function (optional).
