Abstract

Matrix for analysis of low molecular weight compound by MALDI-TOF MS was investigated. We found the new type of matrix, 5-aryl-1H-tetrazoles, which are suitable for the detection of low molecular weight compound ions. When propranolol hydrochloride was measured with 5-aryl-1H-tetrazoles, the strong matrix-derived peaks are not detected in low mass range.
