摘要: A method includes the steps of dipping a capillary (e.g., a disposable glass capillary) into a food matrix to deposit a food sample on the capillary; attaching the capillary onto an Atmospheric Solids Analysis Probe (ASAP); loading the ASAP into an atmospheric pressure ionization (API) source enclosure; ionizing the food sample on the capillary within the API source enclosure; and analyzing the ionized sample for the presence of one or more phthalates.

摘要: The present invention provides novel, simple and reliable methods for extraction of fat soluble vitamins (FSVs) from a sample matrix obtained from food products (e.g., vitamin-enriched foods and fortified food matrices) or biological samples. In certain aspects, the invention provides solid phase extraction (SPE) methods. In certain embodiments, the invention relates to two-step elution methods, which provide excellent recovery of all fat-soluble vitamins from complicated food matrices (such as, vitamin-enriched foods and fortified food products) or biological samples in a simultaneous manner. In certain embodiments, the invention uses OASIS® materials as sorbent beds for separating and/or extracting FSVs from the sample matrix.
