Due to its volatility, Formaldehyde is an ideal candidate for gas chromatography. Unfortunately, current methods for analysis were written over thirty years ago when GC/FID wasn’t sensitive enough to meet screening levels. Ongoing innovations in reactor technology make Formaldehyde by GC the preferred approach. Add a Polyarc® or Jetanizer™ to your system to achieve both increased sensitivity and lower detection limits without sample derivatization.
