Instrument Introduction:
Peristaltic pump injection and electrically heated ceramic quartz tube atomizer can perform high-sensitivity ultra trace analysis on eight elements with low sensitivity in atomic absorption method (arsenic As, selenium Se, mercury Hg, lead Pb, bismuth Bi, antimony Sb, tin Sn, tellurium Te). The operation is simple, the analysis speed is fast, and there is less interference. It can be easily combined with any atomic absorption instrument for hydride formation atomic absorption method determination

Technical parameters:
Typical element determination results:
As sensitivity S=0.11ng/ml
Detection limit SL=0.015ng/ml
RSD%=0.82%
Pb sensitivity S=0.21ng/ml
Detection limit SL=0.27ng/ml
RSD%=1.03%


Main features:
Peristaltic pump three channel continuous injection method, with a sample injection volume of 1-5 milliliters per minute
Choose Tygon wear-resistant and long-life pump tubing from the United States, with a lifespan of up to 500-1000 hours
The domestically unique electric heating ceramic tube heating method has the characteristics of long service life, anti-oxidation and pollution-free, safe and reliable. Even if heated for a long time at a high temperature of 1000 ℃, it will not cause damage to the quartz tube
The temperature control device with high-precision LCD display enables the heating speed of the electric heating ceramic tube to be rapid, smooth, and intuitive. The temperature control range is 100-1000 ℃, and the temperature control accuracy is ± 2 ℃, which can accurately select the optimal atomization temperature
The whole machine has a compact structure, small and beautiful appearance. The hydride generation system and control system are integrated in a 180 × 180 × 200mm chassis, and the electric ceramic heating head is installed in a titanium alloy insulation box, which can be conveniently installed on the axis seat of the atomic absorption atomization chamber
