    1. INTRODUCTION Q: What is a Liaison? LIAISON is meant as a universal link between the Picarro isotopic CO analyzer, G1101-I, and the various commercially available sample preparation systems for Bulk Stable Isotope Analysis (BSIA) of solid and liquid samples through combustion using CM-CRDS or for Total Inorganic/Dissolved Inorganic Carbon (TIC/DIC) isotope analysis in solid or liquid samples through acidification using Automate-CRDS.

    2.1.2. GAS Ultra-High Purity (UHP) Nitrogen supply. If the Nitrogen dry gas is supplied from a high-pressure cylinder, a dual stage regulator is recommended to bring the pressure down to the required 35 psi. If an internal Nitrogen gas supply system is to be used, be sure facilities managers supply the appropriate pressure regulator.

    2.1.3. OTHER PARTS A. 1/8” diameter metal tubing (stainless steel) for gas delivery. a. The length will depend on the distance between the analyzer and gas supply. Measure the distance between the location of the gas cylinders and where the analyzer will be placed, and add to this distance least 5 additional feet (you can’t have enough tubing!).
  • Page 7 cross connector. Order Info: Swagelok SS-3M0-R-2 d. Reducer to go from 1/8” to 2mm tubing. The supply of N carrier gas to the CM unit is through 2 mm o.d. stainless steel tubing. This reducer looks identical to piece 1.1.6, but with a 2mm inlet. It will allow you easily supply this flow from the cross connector.

    D. Snoop for rapid detection of leaks in Swagelok connections (note: a 1:1 solution of Methanol: Water in a squirt bottle can also be used). a. Use this to test gas leaks in any connections upstream the Liaison. Leaks will at the least increase your gas consumption, and at the worst pose a health and safety hazard by displacing ambient air and reducing O to toxic levels or even pose a potential explosion hazard.

    2.4. Getting started 2.4.1. For best results, the sample loaded on the combustion front-end should provide a CO concentration of 2000-4000 ppm, which corresponds roughly to 400 – 1000 µg of carbon. The exact amount of each sample type must be determined independently. Each analyzed sample will be labeled as “good”...
  • Page 21 The sample description needs to be entered between quotation marks, as shown below: 2.4.10. The template file is located in C:\Picarro\Host. You can load the sample description at any point during the analysis by clicking on the “load sample description” button and choosing the relevant sample description file.
  • Page 22 2.4.11. As the samples are analyzed, the results will be reported in the upper part of the coordinator as displayed below: 2.4.12. The bottom half of the coordinator window serves as the log/status of all the processes taking place within the Liaison interface during sample analysis.
  • Page 23 2.4.15. The output results file is a *.csv format saved in the C:\Picarro\IsotopicData folder. The file is automatically saved with the naming system: “CxDS2xxx-YYYMMDD.csv” If you wish to analyze the data file before the run is over, do not open a live copy as this can cause some data to be lost.

    2.5.2. The Gas Sampling Bags are consumables that can deteriorate with usage duration. An extra bag has been provided with the Liaison interface for your convenience. (More bags can be ordered directly from Picarro). Any induced wear and tear in one of the gas sampling bags will eventually form a gas leak on the bag surface or seam.
  • Page 25 2.5.4. The periodicity in the “leak” pulses, such as the example shown above, indicates that the leak is coming from one specific bag since the three bags sequentially alternate with analyzed samples, as the multi-port valve rotates at the end of each sample analysis. The leaky bag needs to be replaced.
  • Page 26 2.5.6. In this case check the connections between the Liason interface and CRDS analyzer as well as the quick-connect/press-fit connections at the bag valve. Liaison Interface for the CM-CRDS User’s Manual Rev A (4-17-2012) Part Number 40026...

    3.3. FAQ The following are questions and answers we’ve compiled over the years while working with Picarro customers. 3.3.1. Regarding Bag Installation and Flow Check A. Make sure that the CM is in "work" mode (flows are on by pressing work + enter).
  • Page 34 it has 100ml/min of N2 coming out of it. If not, then you can adjust it using the purge knob (see the manual attached). This will help push out any atmosphere seeping into the Autosampler. Also, please make sure that you have the plastic lid/cover of the Autosampler on, when running samples.
  • Page 35 3.3.3. Questions about Memory Effect A. Q: Can I increase my oxygen loop to Semi-Micro? There is no major issue with increasing the oxygen loop to Semi-micro. Any excess O2 will be trapped by the copper pellets (Cu => CuO) in the bottom half of the reactor, which is the reducing catalyst.
  • Page 36 C. Q: Can we use air for the pneumatic Autosampler? Regarding using air for the pneumatic AutoSampler, you will save a little, since the pressurized gas is used to push the piston in one direction to drop the sample and then is blocked again. The major consumption of N2 is by the CM itself at 80ml/min when running continuously.
  • Page 37 3.3.5. More Questions A. Q: Why does my coordinator show an overly high concentration of CO2 even after the completion of sample analysis? The high concentration is coming from the remainder of the gas in the gas bag and the tubing. If you close the coordinator, and then choose to "run the final state"...
