(REMPI), the system enables soft, non-fragmenting ionisation of volatile organic compounds directly from the gas phase during roasting, with a time resolution in the sub-second range. This allows the continuous [...] aroma markers such as pyrazines, furanones, and aldehydes throughout the entire roasting process. One of the main technical challenges is the development of a high-pressure-compatible sampling interface. This [...] while preventing condensation and analyte loss, ensuring reliable transfer of the process gas into the ionisation source. The acquired spectral data will be processed using multivariate statistical methods
