  • High concentration.
  • Acetonitrile solvent—suitable for HPLC analyses.
Description

Sampling for airborne carbonyl compounds in EPA Method TO-11A and other methods is based on a reaction between the target compounds and 2,4-dinitrophenylhydrazine (DNPH), coated on a silica gel adsorbent. We introduced a 15-component aldehyde/ketone-DNPH calibration mix (cat.#31808). To meet the needs of investigators analyzing only for formaldehyde, we offer this formulation.

Formaldehyde-DNPH (1081-15-8)

*The reported concentrations reflect the amount of formaldehyde in the mixture. The concentration of derivatized formaldehyde is not reported.
