PICARRO GAS ISOTOPIC ANALYZERS

High precision isotope analyzers to measure and quantify stable isotope ratios resolving biochemical processes encoded in your sample (solid, liquid or gas).

Patented Picarro cavity ring-down spectroscopy (CRDS) technology enables an effective measurement path length of up to 20 kilometers in a compact cavity (temperature and pressure controlled), providing exceptional precision & sensitivity in a small-footprint analyzer. The analyzer maintains high linearity, high precision, and high accuracy over a twofold dynamic range with minimal calibration required. The systems are suitable for field-based monitoring as well as laboratory application, and can be paired with a variety of peripherals to extend and expand functionality. Additionally to isotope ratios, the analyzer also reports gas concentrations.
