Organic Compound Comprehensive Tester RoHS 2.0 Tester LC-2800G Plus

1、 Industrial applications

The organic compound comprehensive tester, abbreviated as HPLC, is an analytical method for separating organic substances. As an important branch of chromatography, liquid is used as mobile phase, and high pressure infusion system is used to pump mobile phase such as single solvent with different polarity or mixed solvent with different proportion and buffer solution into chromatographic column with fixed phase. After each component in the column is separated, it enters detector for detection, so as to realize analysis of sample.
