Title:
METHOD AND DEVICE FOR ANALYZING CHEMICAL SUBSTANCES
Document Type and Number:
WIPO Patent Application WO/2000/062052
Kind Code:
A1
Abstract:
A method for analyzing a sample on a mass spectrometer, wherein the sample is electrochemically treated before being assigned to a mass spectrometer, whereby molecular structure-related information (structural information) can be constantly obtained from fragment ions measured by a mass spectrometer to thereby provide a high-accuracy analyzing method in terms of specificity and sensitivity.
