In this paper, we have described the effective and fast derivatization method for simultaneous determination of EG, PG and GA
in human serum and urine using GC-FID. The conditions of parallel
derivatization by isobutyl chloroformate and phenylboronic acid
have been optimized using experimental design. 3-(4-Chlorophenyl) propionic acid was chosen as an internal standard to avoid the
possible interferences from naturally occurring endogenous acids.
Presented method is a cost effective alternative to well established
GC–MS methods utilizing substantial volumes of rather expensive
silanization agents with minimized sample pretreatment and
turnaround time about 30 min, which is required for timely
effective support of a diagnosis of suspected ethylene glycol
poisoning and to initiate adequate treatment. The assay was
successfully applied to measurements in our routine clinical
practice and the results were also presented.
