Popis:	A new liquid matrix referred to as DTT/NBA, a 1 : 1 (v/v) mixture of dithiothreitol (DTT) and m-nitrobenzyl alcohol (NBA), has been prepared on the basis of a criterion for the choice of matrix in fast atom bombardment mass spectrometry. The capability of DTT/NBA was examined by comparing with those of conventional matrices from the points of durability and chemical inertness. The durability of DTT/NBA was more than ten minutes under the irradiation of fast atom beam, and the mass spectral patterns obtained little varied over the irradiation time. The DTT/NBA matrix inhibited from a degradation reaction of O-acyl oximes, while conventional matrices used here brought about a reductive degradation.
