Description
| - A high-performance liquid chromatographic/mass spectrometric method (HPLC/MS) has been developed to determine both 4-methylimidazole (4MeI) and 2-acetyl-4-(1,2,3,4-tetrahydroxybutyl)imidazole (THI) in one run. Among three sorbents tested, the best peak shape of 4MeI was achieved on a reversed phase MetaChem Polaris C18-A at pH 9.5. The on-column limits of detection were 0.147 ng of 4MeI and 0.084 ng of THI using UV detection and 1 pg of 4MeI and 3 pg of THI using ESI/MS detection, respectively. The method could be applied for a fast and sensitive determination of 4MeI and THI in different biological materials as well as in Class III Caramels.
