The Picarro G2106 Ethylene (C2H4) Analyzer is a real time, trace gas monitor capable of measuring
C2H4 with parts-per-billion (ppb) sensitivity. Our unique CRDS analyzer is a time-based measurement system that
uses a near-infrared laser to quantify spectral features of molecules in a sample gas passed through an optical
measurement cavity. An effective path length of up to 20 kilometers inside the cavity results in exceptional instrument
precision and sensitivity. Picarro analyzers use a small 35 cc volume cavity, ensuring better temperature stability,
faster gas exchange, lower noise and higher sensitivity. Precise cavity temperature and pressure control is designed
into the system to ensure accurate measurements over very long periods of time. Picarro CRDS systems also include
a patented, high-precision wavelength monitor that makes certain the analyzer only monitors spectral features of
interest. This virtually eliminates spectral “noise” from interfering species.
The analyzer is exceptionally rugged, with minimal drift and essentially maintenance free. It requires virtually no
consumables, thereby offering significant ease-of-use and cost of ownership benefits. Easily transportable from site to
site, the analyzer can be set up and running within minutes, and typically requires no sample preparation or drying.
The gas concentration is displayed in real-time with no post-processing required, and is continuously archived to the
analyzer’s internal hard drive. Designed to operate both in laboratories and in harsh environments, it can operate for
many months without user interaction. The software includes a valve sequencer, capable of automatically controlling
up to six external solenoid valves and a rotary valve.
