Cavity Ring-Down Spectroscopy Analyzer for Hydrogen Peroxide - Pharmaceutical Manufacturing and Biotech Uses
CRDS Analyzer for H2O2 - G1114
- 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
Vapor phase H2O2 is used for biodecontamination in many pharmaceutical processes. The importance of measuring the concentration of the H2O2 is considered critical. However, satisfactory technologies for performing such a measurement at the required ppb level are not readily available. The rugged, self-contained Picarro G1114 analyzer supports such efforts, by providing extremely sensitive and precise measurements from one or more measurement points. No dilution, concentration or other sample prep is required. The G1114 can be operated as a remote, unattended monitoring station.
Because the G1114 analyzer is based on CRDS technology there is no crosstalk between the H2O2 and other entities such as H2O and the H2O2 measurement is unaffected by changes in other gas species. Also, data are immune to changes in ambient temperature and pressure. And the G1114 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.
