Abstract
Official abstract text for this publication.
The present invention provides liquid chromatography-mass spectrometry methods and kits for the specific, sensitive and rapid detection as well as quantitation of free amino acids in samples following High Pressure Liquid Chromatography (HPLC) separation.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of analyzing a sample suspected of containing free amino acids using liquid chromatography-mass spectrometry, comprising: preparing a sample to obtain free amino acids; separating the free amino acids by liquid chromatography using a series of at least two chromatographic columns including (a) a first chromatographic column including a graphitic carbon packing material to separate negatively-charged interferents from the free amino acids, followed…
