SUNNYVALE, Calif., March 3 /PRNewswire/ -- Picarro, Inc. has introduced
a unique gas analyzer to precisely measure oxygen and hydrogen isotopes in
water vapor, important markers used in source of origin monitoring, and
water cycle and climate studies. This new analyzer fills a previously unmet
need for continuous, in situ, moisture and isotopic ratio measurements.
Since it can be deployed in the field as well as the laboratory, the
Picarro Isotopic water vapor analyzer will be key in environmental studies
such as understanding the global water cycle. For this application, this
analyzer eliminates the need for flask sampling and enables fast,
continuous, on-site isotopic measurements which simply cannot be done with
larger, costlier IR-MS systems.
Industrial applications include pinpointing sources of moisture
contamination in manufacturing processes and accurately measuring the point
of origin of foods, beverages and pharmaceuticals. Furthermore, the
analyzer reports precise total moisture concentration measurements in
addition to isotope concentration.
"Isotopes are notoriously difficult to measure because of the
complexity and cost of legacy techniques like magnetic sector mass
spectrometers," said Michael Woelk, President and CEO of Picarro. "The
Picarro Isotopic Water Vapor Analyzer is a huge step in simplifying and
cost reducing isotopic measurements for scientists and engineers regardless
of skill level, point-of-measurement or budget". Based on a new, compact
platform, the analyzer measures single spectral features in a flow cell
with an effective path length of up to 12 kilometers resulting in increased
sensitivity, selectivity, precision, and data quality. Its high resolution
and resulting specificity enable it to discriminate between closely spaced
spectral lines arising from different isotopic compositions in the sample
gas. The analyzer is exceptionally rugged, offers extremely low drift, is
basically maintenance free, and requires no consumables, thereby offering
users significant ease of use and cost of ownership benefits.
Recently, stable isotope techniques have been used to enhance
micrometeorological studies of the biosphere-atmosphere exchange processes
in ecosystems. They are increasingly being used to address challenging
problems such as identifying the primary components of net carbon and water
fluxes to help evaluate their response to climate variations and land use
change. The ability to detect equatorial to polar regional variations of
these isotopic markers further enables studies to understand climate change
The analyzer is based on the company's exclusive implementation of
cavity ring down spectroscopy (CRDS) technology, originally developed at
Stanford University and licensed in 1999 to Picarro, where it has been
further developed and commercialized.
Picarro, Inc. is a privately held company dedicated to developing
instrumentation for the precise measurement and identification of specific
molecules of interest to environmental and atmospheric scientists,
geophysicists, and others monitoring the effects of global warming and
change. The company is a leader in cavity ring down spectroscopy (CDRS)
with eight exclusive licenses to Stanford University patents and nine
of its own on CDRS extensions. Visit us at http://www.picarro.com.
