Our advantage

1, double layer cast aluminum plate structure, cast aluminum structure optical path (optical element fasteners base 20mm cast aluminum plate), most manufacturers on the market for sheet metal structure, cast aluminum structure for a long time high temperature use is not easy to deformation, and good heat dissipation, to a large extent to ensure the stability of the optical path structure (good stability), long distance transportation or bumpy its optical path structure is not easy to change;

2, the instrument graphite furnace method of light temperature control directly monitoring the temperature of the inner wall of the graphite tube, closer to the sample, making the temperature rise more smooth and stable, other companies are basically testing the outer wall of the graphite tube, the value of the inner wall detection is more accurate and effective, and more suitable to test the sample, the sample detection is more accurate;

3, wavelength precision screw drive, for four subdivision drive, step can be accurate to 0.005nm, other basic no subdivision, step is 0.02nm, is four times of other companies, greatly increasing the accuracy and repeatability of the instrument wavelength;

4. The background of deuterium lamp buckle is deuterium hollow cathode lamp and other companies use deuterium arc lamp. Deuterium hollow cathode lamp has long service life and is not easy to heat, but deuterium arc lamp has low cost, short service life, and is easy to heat and damage

5, detection limit: according to the sensitivity of different elements, the detection limit of each element is different, the higher the sensitivity, the lower the detection limit, copper: 0.002ug/ml, cadmium: 0.0002ug /ml

6, the application technology of hydride method is mature, the instrument test can be repeated two to three times, take the average, the same industry can only read once, including imported instruments;

7, the classic graphite furnace circuit, the first in China, using KCB472 thyristor trigger transformer structure design, fully enclosed printed circuit board directly welding installation; Graphite furnace circuit board is easy to aging, power has been working temperature easy to damage, the United States analysis company hired retired experts, to provide technical support for the upgrading of the circuit board, to avoid the damage caused by instantaneous temperature rise, precise control of the temperature of the graphite furnace, integrated circuit installation is convenient.

8, abnormal automatic alarm, automatic shutdown system, automatic power off can save the measurement data, the internal use of stainless steel pipeline, avoid plastic pipeline aging phenomenon.
