Installation notes for software scripts to conduct 50 ml syringe sample measurements with Picarro G2131-i and G2201-i gas analysers.

For explanation of method see publication Dickinson et al. "System for del13C and xCO2 analysis of discrete gas samples by cavity ring-down spectroscopy"

To install and access software scripts for syringe measurements:

1. Choose the appropriate script(s) for your analyser and install these directly into the following directory:

	C:\Picarro\G2000\AppConfig\Config\Coordinator\


2. The scripts operate with the Picarro Coordinator program and are accessed through the Coordinator Launcher.
However, the "CoordinatorLauncher.ini" file must be modified to make our scripts accessible. 
The instrument "CoordinatorLauncher.ini" is found at the following location:

	C:\Picarro\G2000\AppConfig\Config\Utilities\


3. Open the "CoordinatorLauncher.ini" file with a text editor (e.g. NotePad++) and insert the following entries as appropriate into the body of the file:

[Syringe sample measurement G2201i All modes (HP+HR+CO2 recomm.)]
CoordinatorIni = C:\Picarro\G2000\AppConfig\Config\Coordinator\Coordinator_DickinsonMethod_2201_ALL.ini
Arguments = --has_pause --no_sample_num

[Syringe sample measurement G2201i HP-iCH4 + iCO2]
CoordinatorIni = C:\Picarro\G2000\AppConfig\Config\Coordinator\Coordinator_DickinsonMethod_2201_HP_iCH4.ini
Arguments = --has_pause --no_sample_num

[Syringe sample measurement G2201i HR—iCH4 + iCO2]
CoordinatorIni = C:\Picarro\G2000\AppConfig\Config\Coordinator\Coordinator_DickinsonMethod_2201_HR_iCH4.ini
Arguments = --has_pause --no_sample_num

[Syringe sample measurement G2201i iCO2]
CoordinatorIni = C:\Picarro\G2000\AppConfig\Config\Coordinator\Coordinator_DickinsonMethod_2201_iCO2.ini
Arguments = --has_pause --no_sample_num

[Syringe sample measurement G2131i]
CoordinatorIni = C:\Picarro\G2000\AppConfig\Config\Coordinator\Coordinator_DickinsonMethod_2131.ini
Arguments = --has_pause --no_sample_num


4. Save the amended Launcher and exit. You should then be able to access the measurement scripts from the Coordinator Launcher menu. Activate and follow the on-screen instructions and consult notes in the scripts / publication for effective operation. Note that on the G2201-i you need operate the instrument in the appropriate mode for the relevant script (the "ALL" script will work in any operation mode but not all data fields will always be filled).

(As an alternative to modifying the existing CoordinatorLauncher.ini file you can simply substitute for our modified file. Be sure to save separate copies so as to not lose any system functionality.)


5. A template sample descriptors file "SampleDescriptorsTemplate.csv" is included for uploading descriptors to your measurements - which is done within the Coordinator program during measurements. There are 3 fields available for customising sample descriptions ("description", "vessel", "measurement").


6. Output results are saved into a CSV file at the following default directory (can be amended):

	C:\Picarro\IsotopicData\
