Characterization and determination of formaldehyde oligomers by capillary column gas chromatography
Journal Article

· Anal. Chem.; (United States)
A method has been developed for characterization of formaldehyde oligomers in methanol-water solutions as their trimethylsilyl derivatives, utilizing capillary gas chromatography with ammonia chemical ionization mass spectroscopy. The Me/sub 3/Si oligomers form stable adducts with the ammonium ion, (M + NH/sub 4/)/sup +/, permitting assignment of their molecular weights and structures. Quantitative analysis of formalin was accomplished by calibrating the flame ionization detector for molar response to the oligomers by use of closely related compounds. By this method, the total formaldehyde content of formalin solutions was accounted for and the distribution of formaldehyde in the individual oligomers accurately determined. 10 references, 5 figures, 2 tables.
