Designed by LC-MS bioanalysts for LC-MS bioanalysts, QuanRecovery Vials with MaxPeak HPS reduce peptide and protein losses due to ionic interactions and non specific binding. A reduction in these losses lead to higher recovery, sensitivity and repeatability in analytical results. These 300μL vials are LC-MS autosampler ready, with low resudual volumes to fully utilize low sample volumes. MaxPeak High Performance Surfaces are new and innovative technologies designed to increase analyte recovery, sensitivity and reproducibility by minimizing analyte/surface interactions that can lead to sample losses.
