Original language name

Solid-phase extraction of 4(5)-methylimidazole (4Mel) and 2-acetyl-4(5)-(1,2,3,4-tetrahydroxybutyl)-imidazole(THI) from foods and beverages with subsequent liquid chromatographic-electrospray mass spectrometric quantification

Original language description

Solid-phase extraction using SCX Disc cartridges was used for isolation of the analytes from liquid samples. The lower LOQ was 0.1 ng/mL for 4MeI and 0.2 ng/ mL for THI. The linearity of the calibration curves was satisfactory as indicated by correlationcoefficients 0.999. The CV for the intra- and inter-day precision was 5% (n = 6); the accuracy was in the range 98-103 %. The recovery was 97 and 98% for THI and 4MeI, respectively. The method was used to determine THI and 4MeI in beverages, coffee, caramel colours and other samples.

Extrakce 4(5)-methylimidazolu (4Mel) and 2-acetyl-4(5)-(1,2,3,4-tetrahydroxybutyl)-imidazolu (THI) tuhou fází z potravin a nápojů a následná analýza tandemem HPLC/ESI

Czech description

Extrakce tuhou fází s použitím SCX Disc byla použita pro isolaci analytů z tekutých vzorků; účinnost extrakce byla 97 MeI) a 103 % (THI). Limit kvatifikace pro 4MeI byl 0,1 ng/mL a pro THI 0,2 ng/ mL. Kalibrační závislost byla lineární s korelačním koeficientem 0,999. Metoda byla použita pro analýzu piva, kávy, karamelových barviv a dalších vzorků.
