The invention discloses a method for rapid determination of free formaldehyde in textiles, including sample pretreatment, extraction liquid collection, derivatization and enrichment, preparation of a sample holder (1), MSPD extraction and MSPD-DART-MS analysis, DART ion The source (7) and the mass spectrometer (8) are respectively placed on both sides of the sample holder (1), and the metastable plasma ejected by the DART ion source (7) directly desorbs the derivative on the cotton swab head (6) The product, the ionized derivative product, enters the mass spectrometer (8) through the mass spectrometer inlet for analysis. The method for rapidly determining free formaldehyde in textiles of the present invention establishes a rapid detection method based on atmospheric pressure open ionization-mass spectrometry technology for formaldehyde in textiles. |
