hydride generation

The HGA-900 hydride generator is an auxiliary instrument of atomic absorption spectrophotometerUsed for the determination of trace (ppb level) heavy metal elements by hydride atomic absorption spectrometry(Arsenic As, Selenium Se, Antimony Sb, Bismuth Bi, Tin Sn, Lead Pb, Tellurium Te, Germanium Ge, Cadmium Cd, Mercury Hg) can significantly improve the analytical performance of atomic absorption spectrophotometers, expand the range of elements that can be analyzed, improve the sensitivity of heavy metal element analysis, reduce analysis costs, and have high cost-effectiveness.

Model Description:

HGA-900 type, equipped with imported atomic absorption spectroscopy

hydride generationProduct performance:
This instrument adopts the hydride atomic absorption method flow injection method. Low sampling volume, high sensitivity, and low detection limit.

The following is the measured data of sensitivity (ng/mL/1% A) for any selected generator of this type:

(1) Good stability

The relative standard deviation (coefficient of variation) of the error indicator RSD is less than 4% (which can actually be less than 2%). Edingshen: As 6ng/mL absorbance is between 0.2-0.5, it was measured 11 times and calculated.

（2）Low detection limit

Calculated at 3 times the standard deviation, a value of approximately 2/3 of the sensitivity (in ng/mL) can meet the measurement requirements of as low as 0.01-0.1ppm in the sample.

（3）High degree of automation

Just press the start button to automatically complete the entire process of sample injection, generation, and reading (the host needs to have remote automatic reading function) and cleaning.

（4）high efficiency

Excluding sample pre-treatment, word determination time is less than 30 seconds. Generator usage conditions are adjusted, except for the carrier gas, which is preferred without labor.

（5）Adaptable

Both new and old models of atomic absorption spectrophotometers at home and abroad can be used, and peak height and peak area readings can be obtained, as well as continuous method readings (such as trend or integration), and peak height readings can also be obtained by visual method or recorder.

（6）Unlimited continuous working hours

The gas-liquid separator is involved and does not require the use of desiccants.

（7）Lightweight and compact in size

Net weight of approximately 3kg, length 260mm, width 218mm, height 230mm

Stable quality, low failure rate, easy installation, and convenient maintenance.

（8）Exquisite drop electric quartz absorption tube

The processed electric heating wire is tightly and evenly wrapped around the quartz tube without short circuiting. It is easy to install and remove (with matching inserts inserted into the combustion seam) and adjust the position. The temperature can be adjusted and the service life is long. A special measure to improve atomization efficiency that pure electric vehicles cannot achieve.
