Carbohydrate and steroid analysis by desorption electrospray ionization mass spectrometry.
Desorption electrospray ionization mass spectrometry (DESI-MS) is applied to the analysis of carbohydrates and steroids; the detection limits are significantly improved by the addition of low concentrations of salts to the spray solvent.
