Application of direct analysis in real time (DART) and direct inlet probe (DIP-APCI) mass spectrometry in the context of industrial sample analysis

In today’s industry, quick and reliable analytical methods play an important role for quality control. On that account, two emerging techniques, namely direct inlet probe-atmospheric pressure chemical ionization (DIP-APCI) and direct analysis in real time (DART) mass spectrometry, are particularly promising. In case of a DIP-APCI source, small amounts of solid or liquid samples can be studied without sample pre-treatment. A similar system is the DART ion source. In addition to the analysis of solid and liquid samples without pre-separation, this ion source offers the possibility to scan the surface of a sample. A method for industrial sample analysis focusing on the study of delamination of coatings from a panel was developed using DIP-APCI-Q-TOF-MS and DART-Q-TOF-MS, respectively. Comparative studies based on the conventional pyrolysis–GC–MS were carried out.
