·Product Discription 4520B-Q is a multi-functional AAS applied to the fields of food, feed and so on. The built-in design of hydride generator in 4520B-Q is the nationwide origination, which saves more areas and gets better stability. The measured elements contain: lithium, sodium, magnesium, potassium, calcium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, rubidium, strontium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, indium, tin, antimony, tellurium, cesium, osmium, iridium, platinum, gold, thallium, lead, bismuth, germanium, arsenic, selenium and mercury. The basic parameters of this instrument meet the standards of JJG694-2009.
·Product Features 1. Three-lamps position, the number of preheating lamps is user-defined so that the waiting time in working process can be solved. 2. The lamp position can optimize automatically and adjust for three-dimensions to maximize the energy. 3. The elements have the functions of negative high-voltage self-memory, wavelength scanning, lamps self-optimization and energy optimization with one key step. 4. It is convenient for the testing results to be exported by various formats and operated by office software. 5. This system can be remote controlled so that its problems can be solved in time with remote control technique. 6. The built-in hydride generation device can detect the low temperature elements, such as mercury, arsenic and selenium.
