Title: LC-MS configuration for purification and detection of analytes having a broad range of hydrophobicities
Inventor: HERMAN JOSEPH L
IPC: G01N33/84
Filed: 2011-10-28
Granted: 2017-04-06
Abstract: Systems, apparatuses, kits, and methods for purification and analysis of analytes having a broad range of hydrophobicities by liquid chromatography-mass spectrometry (LC-MS). Using one set of liquid chromatography columns, one set of mobile phase buffers, and, optionally, a single ionization method (e.g., electrospray ionization), a wide range of analytes can be purified and analyzed on a liquid chromatography-mass spectrometry (LC-MS) system. LC-MS purification and analysis of analytes having a broad range of partition coefficients is accomplished by selecting LC run parameters and MS system parameters that are particular to different classes of analytes without having to make column or buffer changes or any other hardware configuration changes to the LC-MS system. The methods, systems, and kits described herein provide for substantially increased speed/throughput and ease of use for a wide range analytes with essentially no compromise in specificity for individual analytes relative to previously described methods.
