The URG-3000N Carbon Sampler is designed to sample for organic and elemental carbon found in ambient PM-2.5. The measurement of ambient carbon species is an important part of the United States National PM-2.5µm Chemical Speciation Network (CSN).

The URG-3000N has been designed for the USEPA to achieve comparable data with the carbon measurements of the Interagency Monitoring of Protected Visual Environments (IMPROVE) PM-2.5 carbon module.
