TI  - Determination of low-molecular mass aldehydes by automated headspace solid-phase 
      microextraction with in-fibre derivatisation.
PG  - 147-54
AB  - Headspace solid-phase microextraction (HS-SPME) analysis of low-molecular mass 
      (C1-C10) aldehydes in aqueous solutions was investigated, using 
      pentafluorophenylhydrazine (PFPH) and 
      o-2,3,4,5,6-(pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) as in-fibre 
      derivatisation reagents. Analysis of the derivatives was achieved, using GC-flame 
      ionisation detection (FID). A comparison of the two reagents showed that PFBHA 
      was superior to PFPH under the investigated conditions. Fundamental studies of 
      the PFBHA and PFPH reactions showed that the kinetics of the process was limited 
      by the mass transport rate of the analytes to the fibre. The developed PFBHA 
      method gave detection limits in the low to sub-microgram per litre range for most 
      of the aldehydes tested. The method was applied successfully to the analysis of 
      particleboard, wine and fish samples.
