Can DART mass spectrometry be used to preprocess lipids? For example, baseline correction, denoising, peak extraction, deconvolution, alignment, and then extract the data.
DART mass spectrometry can indeed be used for the analysis of oils and fats, but it does not involve traditional sample pretreatment.
DART mass spectrometry itself is an ionization and direct detection technique and does not provide baseline correction, denoising, peak extraction, deconvolution, or alignment of data as preprocessing functions. These data processing steps are usually performed through subsequent data processing software rather than being directly implemented in the DART mass spectrometry hardware or ionization process.
The core advantage of DART mass spectrometry is that it is a rapid ionization method that requires no sample pretreatment, allowing direct analysis of components in complex matrices like oils and fats. In oil analysis, DART-MS can directly detect compounds volatilized from the sample surface, making it particularly suitable for samples with a significant amount of volatile and semi-volatile components. Therefore, it can be used to quickly identify fatty acids, oxidation products, aroma compounds, and other small molecular components in oils and fats.
