Measure hydrogen peroxide (H2O2)

Picarro G2114 Analyzer

Accurately measure H2O2 without worrying about ambient temperature and pressure.

  • Exceptional sensitivity and precision with minimal calibration
  • Continuous, real-time measurements without interference
  • Large dynamic range with high linearity
  • Installed and operational in minutes
  • Rugged and insensitive to changes in ambient temperature

The rugged, self-contained Picarro G2114 analyzer provides extremely sensitive and precise measurements from one or more measurement points. No dilution, concentration or other sample prep is required. It can be operated as a remote, unattended monitoring station.

Because the G2114 analyzer is based on CRDS technology, there is no cross-talk between the H2O2 and other entities such as H2O. In addition, the G2114 can operate for months between calibrations.

Picarro offers guaranteed performance specifications with every hydrogen peroxide analyzer with lower detection limits of under 10 ppbv with a signal to noise ratio of 3:1.



Hydrogen peroxide is predisposed to adsorption on surfaces and also has water present. It is extremely challenging to measure. The Picarro analyzer's low volume and coated internal components enable fast responses, as shown. 10 to 90% and 90 to 10% response times are under 1 minute for changes between 0 and 10 ppmv hydrogen peroxide.


The spectroscopic similarity of water and hydrogen peroxide make reported hydrogen peroxide concentration dependent upon water concentration for all but the most well controlled spectrometers. Picarro's patented wavelength stabilization allows the analyzer to lock on the spectroscopic signal unique to hydrogen peroxide and eliminate any interference from water vapor as shown here.
