Overcome Nonspecific Binding Challenges in LC-MS Workflows
As drug discovery advances and analyte concentrations decrease, advanced liquid chromatography-mass spectrometry (LC-MS) methods demand unprecedented selectivity and sensitivity. However, a critical but often overlooked challenge threatens method robustness: nonspecific binding (NSB).
NSB occurs when analytes adsorb onto multiple surfaces during sample preparation, injection, and separation, leading to poor, nonlinear, or irreproducible recoveries. While guidelines emphasize consistent recovery, they often miss the impact of sample handling materials—a gap that significantly influences sensitivity, precision, and accuracy.
This white paper investigates the fundamental mechanisms of analyte adhesion to LC vial surfaces, exploring how complex interactions like electrostatic forces, hydrogen bonding, and hydrophobic/hydrophilic interactions cause significant analyte loss.
