The standard deviation of the d13C values of the five sample replicates is outstandingAdvantage Note: For the first time, high-precision, bulk stable isotope analysis (BSIA) of 13C is push-button simple. Meet Picarro’s CM-CRDS system – the world’s smallest foot-print, lowest cost, fully-integrated 13C BSIA instrument. Researchers in food science, material studies, soil and plant studies will benefit from the unparalleled combination of high-precision, low price, ease of use, and remarkable flexibility. The CM-CRDS offers performance comparable with isotope ratio mass spectrometry (IRMS) instruments. Unlike IRMS systems, which require specialized installation, a Picarro CM-CRDS can be installed by non-technical personnel in 2 hours. In fact, virtually anyone can set up and configure this compact, benchtop system for high-precision measurements. The same CM-CRDS instrument stack can move from the lab to the factory to the field in a matter of hours. In contrast, IRMS systems cannot be moved without significant expense and risk. Using CM-CRDS researchers can “set-and-forget” by loading a sample tray and programming the instrument to run as many as 148 unattended samples sequentially. Best of all, the price is right. The Picarro CM-CRDS system costs 2x-3x less to purchase than a comparable EA-IRMS system and costs 5x-10x to operate on an annual basis.The CM-CRDS system consists of the Picarro G2121-i Cavity Ring-Down Spectroscopy (CRDS) isotopic CO2 gas analyzer, the Picarro Liaison Universal Interface, and the Picarro Combustion Module (CM). The CM generates CO2 from the carbon in the sample and routes the gas via the Liaison interface into the isotopic CO2 analyzer. ?e World's Highest Performingand Easiest to Use Analyzers©2010 PICARRO, INC. · 480 Oakmead Parkway, Sunnyvale, CA 94085 · T 408.962.3900 · E info@picarro.com · W www.picarro.comTargeted d13C PerformanceGas Species PrecisionCO2 <0.4 ‰ (0.2-0.3 ‰ typical) sample-to-sampleSystem SpecificationsMinimum sample size 250 µgC (guaranteed precision);400 µgC (typical precision)Sample-to-sample analysis time 10 minCarrier Gas N2 (UHP)Combustion Gas O2 (UHP)Optional Reference Gas CO2 at 3000 ppmv in N2Carrier gas flow rate <90 ml/min of N2 at 760 TorrAutosampler Attached Pneumatic Autosampler w/ 50-position carousel (99 and 148 positions optional)Power Requirements 90-120 VAC, 50/60 Hz & 220, 50 HzInstallation / Weight / Dimensions Benchtop / 160 lbs / 38”x 29”x 23” w/ A/SLiaison manages three processes in parallel for maximum sample throughput. These processes are a) feeding the CO2 collected from one sample into the CRDS, while b) collecting the CO2 generated from a second sample into a gas bellows, and c) purging the third bellows with N2 in preparation for the next sample collection. The entire CM-CRDS system can be controlled with GUI-based intuitive software utilities installed on the Picarro analyzer. Users can connect remotely and control the instrument through a standard Remote Desktop connection or with similar remote login software. Picarro guarantees the specified precision of the CM-CRDS system by running a series of 10 pulses of CO2 standard gas at 3000ppm in N2 and the combustion of six solid samples of USGS40 (L-glutamic acid).Potential uses of the CM-CRDS include food research, soil science, ecology, marine biology, materials science, proteomics, and many other applications. This unique combination of ease of use, high precision, and cost effectiveness positions the CM-CRDS to leverage Picarro’s outstanding Isotopic CO2 Cavity Ring-Down Spectroscopy (CRDS) technology into a plethora of novel 13C BSIA applications that would not otherwise be possible due to cost, time constraints, or inherent complexity of pursuing these lines of research on IRMS systems. Most important of all, the CM-CRDS makes stable isotope technology accessible to an entire new class of users who are not highly-trained spectroscopists, nor have sufficient time to overcome the complexities of the traditional IRMS instrumentation. About Picarro CRDS Picarro’s unique Cavity Ring-Down Spectroscopy (CRDS) system 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. The optical cavity is thermally controlled to ensure minimal drift, even in the harshest environments. Precise temperature and pressure control systems designed into the analyzer ensure accurate measurements over long periods of time as well as allow extremely infrequent calibration. Picarro CRDS systems all include a patented, high-precision wavelength monitor that makes certain the analyzer only monitors spectral features of interest. For researchers, the CM-CRDS delivers a best-in-class combination of flexibility, speed, high-precision, and ease of use that sets a new standard for bulk stable isotope analysis.
