TOC-VWP : SHIMADZU (Shimadzu Corporation) Measurement Principle. Phosphoric acid and the oxidant (persulfate) are added to the sample, which is heated under UV illumination to convert the TC in the sample to carbon dioxide. This carbon dioxide flows with the carrier gas via the dehumidifier into the NDIR sample cell. The area of the carbon dioxide peak signal is measured and this peak Certified TOC Vials | Shimadzu VIAL ONLY, 40ml Clear, for EPA or TOC kits 72 226-50586-00 COMPLETE C...

VOC Guidelines – USGS The stainless-steel sampler holds four 40-mL vials. Copper tubes extend to the bottom of each vial from the inlet ports on top of the sampler.
