Instruments and information



Mass spectrometry is a very sensitive technique that can detect analytes at very low concentrations. Contamination of preparations with keratin and plastisizer can be a problem as they can mask your protein of interest with their greater abundance.

To get the best possible LC/MS/MS analysis, we employ the following protocols. For further information and advice on sample preparation, please contact us and we will be happy to help.
