ABSTRACT:
A method for spectrometric investigation of a plurality of samples dissolved in a solvent comprises: (a) guiding a first solvent with a sample through an SPE cartridge for concentrating the sample in the cartridge; (b) positioning the cartridge in a carrier for a plurality of cartridges; (c) repeating steps (a) and (b) for a desired number of samples; (d) drying the concentrated samples through removal of the residual first solvent, in particular, dehydration or evaporation; (e) dissolving each sample in a second solvent, transferring these dissolved samples from the cartridges to a spectrometer and acquiring a spectrum of each sample. All samples are dried together in step (d) subsequent to steps (b) and (c) while the cartridges with samples are positioned in the carrier. The drying process is thereby considerably accelerated in a straightforward technical manner.
