We also recommend that you check out QuanRecovery with MaxPeak, 700 µL Plates, 25/pk ; QuanRecovery Plates with MaxPeak HPS, designed by LC-MS bioanalysts for LC-MS bioanalysts, reduce peptide and protein losses due to ionic interactions and nonspecific binding. Reduced losses result in improved recovery, sensitivity, and repeatability of analytical results. These 700L 96 well plates are LC-MS autosampler ready, with low residual volumes to maximize sample volume utilization. MaxPeak High Performance Surfaces are new and innovative technologies that are designed to improve analyte recovery, sensitivity, and reproducibility by reducing analyte/surface interactions that can result in sample losses.

FAQ
How Do I Change a VanGuard Cartridge? Cartridge VanGuard Columns are made up of two parts: a reusable holder and a replaceable cartridge. For replacement, the following steps should be taken: Remove the LC inlet tubing from the column assembly first. Use a 7/16-inch and 3/8-inch wrench to remove the cartridge from the holder. It is not necessary to remove the holder from the analytical column. Remove the old guard column and replace it with the new one. Apply the same wrenches to the flats on the cartridge holder to tighten the cartridge. To ensure leak-free collection, connect the LC inlet tubing and use mobile phase flow.
