Adding a Polyarc® Reactor or Jetanizer™ to your GC/FID instrument makes running Formaldehyde by Liquid Chromatography a thing of the past.
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.
