Formaldehyde is a volatile organic compound, and its chemical properties make it an ideal candidate for gas chromatography. Unfortunately, the methods for Formaldehyde analysis call for sample manipulation and liquid chromatography. These LC methods were written thirty years ago, when GC/FID was not sensitive enough to meet screening levels. Advancements in reactor technology now make Formaldehyde by GC easy and accurate. Get low sensitivity without sample derivatization, by adding a Polyarc or Jetanizer to your system. See the data here for real laboratory studies on Formaldehyde and other analytes using GC/FID coupled with ARC Products.
The Polyarc System: Making Formaldehyde Analysis Easy and Accurate
Adding a Polyarc® Reactor or Jetanizer™ to your GC/FID instrument makes running Formaldehyde by Liquid Chromatography a thing of the past.

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
