The gel permeation chromatography system follows the principle of gel chromatography and makes use of the spatial size effect of gel pores to separate molecules of different sizes. Heavily contaminated samples often need to be purified with GPC first, and then analyzed with HPLC, GC, or GC-MS/LC-MS; GPC can eliminate interfering substances in a targeted manner, thereby improving the accuracy of analysis and protecting the analysis system.
High-precision high-pressure constant-flow pump with stable infusion and excellent repeatability; real-time pressure display, high/low pressure alarms, and other functions ensure instrument safety; variable-wavelength UV-visible detector with wide wavelength range and high sensitivity; touchscreen fully automatic fraction collector for simple and intuitive operation; stainless steel gel purification column with good consistency, reducing operation time and improving work efficiency.
The Elite GPC gel purification system boasts numerous advantages including high purification efficiency, simple operation, convenient maintenance, and reliable safety. It is primarily used for sample pretreatment purification during the detection of pesticide and veterinary drug residues, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). This system finds extensive applications in agricultural products, food, environmental monitoring, and life sciences.
