The petrochemical version of the inductively coupled plasma emission spectrometer is designed to meet the testing requirements of the petrochemical industry. It is a chemical analysis instrument specifically designed for the petrochemical industry, which our company has made great efforts to create. Mainly used to determine the content of various elements detected in various types of oil and related products. The instrument innovatively adopts direct oil injection technology, a semiconductor cooled ultra-low temperature mist chamber, and oxygen assisted injection to eliminate the serious carbon deposition in organic samples, greatly improving the applicability of the instrument.
Product Features
1. There are many testing elements, and more than 70 types of elements can be tested. 2. The detection limit is low, and the vast majority of elements can reach the ppb level. 3. Simultaneous testing of multiple elements, secondary injection, and simultaneous testing of multiple elements. 4. Wide linear range, up to 5-6 orders of magnitude, can achieve simultaneous testing of high and low content without the need to replace standard curves. 5. Fast analysis speed, about 5 elements per minute, expandable to 10 elements per minute. 6. No need for digestion, oil samples do not require digestion, and can be directly tested on the machine after simple processing.
