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.

Accurate Quantification of CO and CO2, Formamide, Formaldehyde, and Formic Acid using the Polyarc® Reactor

The Polyarc® converts your FID into a truly universal detector using patented catalytic conversion technology. This system gives your FID a uniform response across almost any organic molecule, allowing your lab to detect more compounds for more accurate data and improved efficiencies.
The Polyarc has enabled me to conveniently quantify low levels of formaldehyde with high level of repeatability. So far, I think it’s a very powerful analytical tool and greatly improves the performance/sensitivity of the FID for substances like formaldehyde which would rather be difficult or nearly impossible to quantify. The Polyarc reactor is the baby of my research.Abubakar Yusuf Energy Technologies PhD Student, The University of Nottingham Ningbo China
