The goal of this study was to develop fast, reliable and simple
method that is not based on silanization for simultaneous determination of EG, PG and GA in blood serum or urine by GC-FID. The
use of GC-FID instrument is advantageous over GC–MS (although
our GC-FID method could be easily transferred to GC–MS method
if desired) because the GC-FID instrumentation is widespread due
its low cost, simple maintenance and the possibility of the use of
hydrogen instead of helium as a carrier gas. Furthermore, GC-FID
instrument could be dedicated to this method solely and operated
by well-trained technical staff without supervision on 24 h daily
service.
