Liquid chromatography - mass spectrometry (LC-MS) combines two approaches to separate and identify molecules or compounds present in a sample. High performance liquid chromatography (HPLC) separates ...
How is LC-MS performed? The sample first undergoes ionization before entering the mass spectrometer. Commonly used ionization methods are electrospray ionization and atmospheric pressure chemical ...
High-resolution, accurate-mass (HRAM) mass spectrometers (MS) are a class of MS instrumentation with capability to resolve complex sample matrix and to allow identification of compounds by measuring ...
Liquid chromatography-mass spectrometry has become a widely used method of quantifying protein expression in many areas of biomedical research, allowing for the highly sensitive and specific ...
