alarming for leaking of combustion gas, over-heated protection for graphite furnace.
Be able to be coupled with the hydride generator, which is heated quartz cell, 3 channels continuous sample pumping by a peristaltic pump.
the generator is capable of automatically perform high sensitivity ultra trace analysis for 8 elements (As, Se, Hg, Pb, Bi, Sb, Sn and Te) in one single system.
Optional of graphite furnace and flame autosampler, realizing automatic preparation of standard solutions, to automate the analysis process.
Easy to switch between flame and graphite furnace in 1 second.
Safety improvement with seal-water for the flame: a sensor and solenoid valve control is provided in the seal water bucket, it safeguards the ignition of flame to prevent the acetylene leaking due
to water shortage of seal-water.
The height of the burner head is adjustable automatically in searching the most optimized position.
Improvement with the calibration curve algorithm, be more flexible and accuracy.
Improvement of self absorption background deduction was accomplished. Also the improved D2 lamp background deduction is provided.
