iso FLOW GHG High performance sample preparation system for trace greenhouse gas isotope analysis High sensitivity High data quality Great flexibility Ease of use Market leading isoprime precisION stable isotope analyzer iso FLOW GHG sample preparation system with autosampler A powerful combination. Greenhouse gases in the atmosphere are major drivers for climate change and so it is essential that we uncover the complex cycling mechanisms of these gases throughout the natural world. At the same time, we must seek to understand the anthropogenic contribution of these gases so that we can develop successful strategies to mitigate and counter- act humankind‘s damaging impact on the careful balances in the natural world. Isotopic analysis of atmospheric greenhouse gases (GHGs) is a critical tool in climate research thanks to the ability for isotopic analysis to elucidate the origin of a sample. The iso FLOW GHG is a fully automated, continuous flow preparation system for the isotopic analysis of greenhouse gases originating from a range of sample matrices and is a key tool in the fight against climate change. Trace concentrations of CO 2, N 2O and CH 4 in atmospheric samples are measured using cryogenic pre-concentration, gas chromatography and chemical traps to deliver the highest precision isotopic analysis. iso FLOW GHG High precision analysis of greenhouse gases The analysis of your precious samples using the iso FLOW GHG is made substantially simpler thanks to the complete automation of the instrument. Using electronic flow and pressure controllers to precisely deliver gases and control sample flows throughout the system, all of which are under control from lyticOS ® software leads to significantly reduced operator contact time. Automated system checks, leak checking and system configuration changes makes the instrument easier to run for operators with diverse levels of experience. Complete automation Flexible sample handling Extend your ? 15N analysis further iso FLOW GHG KEY FEATURES • Capacity for up to 2 capillary GC columns with a maximum temperature of 300 °C • Automated control of all parameters driven by modern lyticOS ® software • Reduced consumption of laboratory resources with sleep?/?wake-up functionality • Flexible sample handling options for multiple sample types • Dual-core needle for analysis of dissolved nitrate and gas samples from septum sealed vials • Optional 1,500 °C high temperature furnace • Optional N 2?/?N2O simultaneous analysis • Optional autosampler with capacity for up to 220 samples • Optional automated LN 2 dispenser for extended analytical run times INNOVATIVE CAPABILITIES iso FLOW GHG can accommodate up to two 30 m capillary GC columns in a thermocouple-controlled heated oven with a maximum temperature of 300 °C allowing new possibilities for enhanced GC chromatographic techniques. As well as this, the optional combustion furnace can operate at temperatures up to 1,500 °C allowing researchers to explore alternative furnace chemistries and target novel isotope species. Atmospheric trace greenhouse gas analysis is performed using 100 ml, ?ow-through sample ?asks. For high throughput analysis of gases and the determination of dissolved nitrate samples presented in septum- sealed vials the instrument can be equipped with an autosampler compatible with multiple sample vial types with up to 220 x 12 ml sample vials or 70 x 20 ml sample vials. A manual injector port is also optionally available for direct injections of gases into the iso FLOW GHG . The iso FLOW GHG o?ers multiple opportunities to further your analysis. When performing  15N and  18O isotope analysis of atmospheric N 2O, the system can optionally also measure  15N of N 2 atmospheric gas from a single sample vial or fiask. The isoprime precisION isotope ratio mass spectrometer can also be optionally conflgured with a dedicated Faraday collector array for the site-speciflc isotope analysis of  15N of N 2O for better understanding of the biological pathways responsible for the production of N 2O.

Complete automation of every parameter makes operation very simple. Ease of use Source apportionment of GHGs CARBON DIOXIDE The atmospheric concentration of CO 2 has rapidly increased over the past 250 years and is currently over 400 ppm. Isotopic analysis tells us this increase is due to the burning of fossil fuels which are depleted in ? 13C. Isotopic analysis also elucidates the terrestrial biosphere sink of atmospheric CO 2 allowing us to understand how the earth may respond to future atmospheric CO 2 forcing. NITROUS OXIDE Nitrous oxide concentration is very low in the atmosphere (~330 ppb) but it has almost 300x the warming potential of CO 2. Thanks to isotope analysis, we know that approximately 75?% of N 2O atmospheric emissions originate from agricultural activities and the technique is crucial to further our understanding of other mechanisms at play in the global N 2O cycle.

METHANE Atmospheric methane concentrations have been increasing rapidly since 2007 but the reasons for this increase are not clear. We do not know the extent of methane trapped in permafrost or possibly released from wetlands and wildfires. These phenomena have the capacity to form run away feedback loops as further warming increases atmospheric emissions. Coupled with increased production of natural gas due to “fracking“, these sources must be apportioned and isotope analysis is an essential tool to achieve a fuller understanding of the global CH 4 cycle. The iso FLOW GHG sample preparation system provides a fully automated, high performance, compact bench top solution for the isotopic analysis of these trace greenhouse gases.
