Abstract:
A method for the extraction of residual formaldehyde from surgical materials after sterilisation and its gas
chromatographic determination as the 2,4-dinitrophenylhydrazone derivative is described. Quantitative
determinations are made using 9-cyanoanthracene as an internal standard, instead of anthracene, as
reported previously, because this compound is more stable in solution. The sensitivity is of the order of 10
ng ml-1 of extracted aldehyde. To measure the released formaldehyde under the conditions closest to those
of the human body, because of the purpose of these samples, the formaldehyde was also extracted with a
physiological solution (0.9% NaCI), at 37 "C, with and without stirring.
