| Definition | A continuous measurement pCO2 system. It is designed for land or ship-board laboratory use. Water sample is forced into the equilibrator by a shipboard pump. Equilibrated air is drawn from the equilibrator and dried with an electronic cooling system and a Nafion dry tube. It is then quantified with a CRDS CO2 analyser (Picarro G-2301) and/or an infrared CO2 analyser (LI-7000) before returning to the equilibrator. Optional sensors can be integrated. It measures at <100 -3000 uatm. Response time is 2 minutes. Repeatability is <1 ppm. Accuracy is +/- 1 to 2 ppm for pCO2. The detector can be replaced with a LI-850 analyser (pCO2 ranges 0-20,000 uatm) or LI-7815. | ||
