Analysis of Complex Fingerprints
The analytical pyrolysis – coupled with gas chromatography and mass spectrometry (Py-GC/MS) – is magnificently suited in order to characterise organic solids such as micro-plastics, synthetics, dyes, resins, textiles, coatings, oils, sediments, pulps and woods. The chromatographic fingerprints created in this manner enable detailed insight into the composition of the analytes. However, their complexity imposes high requirements on the data analysis.
The Pyrolysis module from labRATry offers the user of the pyrolysis GC/MS many possibilities for designing the data evaluation to be more efficient and more targeted. They include the highly-automated removal of background noise, drift correction (alignment), peak deconvolution, weight sample standardisation, but also the comparison of fingerprints directly with each other or against mass spectra and/or chromatogram databases that have been created. Furthermore, the principal component analysis (PCA) offers the option of identifying marker components. Please feel free to talk to us in order to find out more.
