Abstract
A method for detecting a substance or substances in a sample or in a matrix of samples combining detection methods that are, on the one hand, based on direct detection with integrated optical (bio)chemo-sensitive waveguide grating structures and, on the other hand, based on a mass-spectrometric detection effected by way of a desorption process. The method permits an increase in detection security and/or detection sensitivity.
