In the G2101-i, a breakthrough water correction software package eliminates the need to dry sample gas, reducing research complexity and consumable costs. Picarro has also improved onboard electronics for higher data quality, and reduced the size, weight, and power draw of the system for better field deployability. Unlike any other analyzer, the G2101-i carries slots for up to four different laser cards, allowing for further measurement capability. The heart of the G2101-i is a sophisticated time-based measurement system that uses a laser to quantify spectral features of gas phase molecules in an optical cavity. Leveraging Picarro’s patented CRDS technology, the G2101-i offers significant performance, ease of use and cost of ownership benefits compared to other absorption based technologies. An effective path length of up to 20 kilometers provides exceptional precision and sensitivity. A patented, high-precision wavelength monitor maintains absolute spectral position, thereby ensuring accurate peak quantification. In addition, this technology guarantees that only the spectral features of interest are being monitored, greatly reducing the analyzer’s sensitivity to interfering species
