Determination of Histamine in Human Serum/Plasma by SPE and HILIC LC-MS-MS

Reversed-phase HPLC analysis of histamine has been a challenge in the past due to the high polarity and poor retention. HILIC (hydrophilic interaction chromatography) offers a potential solution because of high polar analyte retention without the need of strong ion-pair reagents, which are not compatible with mass spectrometry (MS) detection and can cause signal suppression.

Solid-Phase Extraction of Aflatoxins from Peanut Butter and Quantification Using Kinetex Core-Shell Technology by LC–MS–MS

As a result of their high toxicity and carcinogenicity, aflatoxins are of major concern for food producers, the food processing industry and consumers. Most countries have legislation setting maximum permissible limits for aflatoxins, which are in the low micrograms per kilogram for food matrices.
