Spectroscopy (CRDS), on the other hand, is one thousand to one million more times sensitive. In Picarro analyzers, light from a single-frequency laser enters a cavity where three mirrors reflect the laser light as seen in Figure 1. The light...

A cavity containing gas that absorbs light will have a shorter ring- down time than an empty cavity. As the light circulates in a cavity with a gas sample, the molecular absorption by the gas results in a decrease of the light intensity. Picarro G2106 Analyzer User Manual...
Page 9
Determining absorption intensity at a specific wavelength requires comparing the ring-down time of an empty cavity to the ring-down time of a cavity that contains gas. Picarro instruments gather measurements from an “empty” cavity by switching the light to wavelengths that are not absorbed by the target molecules.
Page 10
1.4 Spectral Precision and High Sensitivity Measurements Picarro analyzers contain two features that provide high spectral precision: • Proprietary wavelength monitor (WLM) that measures the absolute laser wavelength to a precision that is a few orders of magnitude narrower than the spectral linewidth: Picarro’s patented WLM measures absolute laser...

For precise pressure control, the cavity pressure is monitored using a high- linearity pressure transducer. The system computer uses this pressure data in a feedback loop to control proportional valves that adjust the inlet and outlet gas flow of the cavity. Picarro G2106 Analyzer User Manual...

7. INSTALLATION This section describes the setup and installation of the Picarro Analyzer. Please read and understand this section thoroughly before proceeding with the installation. Using this analyzer in a manner not specified by Picarro may result in damage to the analyzer and render it unsafe to operate.
Page 23
3. Unpack the analyzer accessories. The Certificate of Compliance and USB drive should be stored in a safe place and may be required if you contact Picarro with questions about your analyzer. Picarro G2106 Analyzer User Manual...
Page 24
7. Connect the analyzer to a power source using the supplied AC power cable. Use the AC power cables supplied with the analyzer or a similarly rated cable. Check with Picarro technical support if you have questions about power cable replacement. An inadequately rated CAUTION power cable can result in equipment damage.

Icons on the desktop are as follows: • Controller- Instrument diagnostics and service information • Picarro Mode Switcher- Restarts analyzer in different measurement mode. Most analyzer models are configured for one mode and may not include the Mode Switcher. (Figure 1). If the analyzer has multiple modes, this allows the user to switch between them easily.

Figure 2 - Layout of the Picarro analyzer GUI, G2000 series. A full explanation of the GUI functions can be found in Appendix B Data will be saved automatically once the analyzer starts to produce data. The data in the GUI is the continuous real time read out from the analyzer. A user relevant subset of this data is stored in C:\Userdata\DataLog_User \YYYY\MM\DD, where Y=year, M=month, D=day.

Figure 3 - Overview generalized schematic of Picarro analyzer system hardware, software, and data file generation. The samples A, B, and C are introduced into the analyzer sequentially by a sampling module, if present. The sampling module could be a set of customer-supplied valves, a valve manifold, a discrete sampling module, or other device.
Page 30
If the power to the analyzer is cut-off for any reason, the analyzer will cease operation. However, when the power is reapplied, the analyzer will restart automatically. The Picarro software tools will also properly close out previous files and open new files for data collection so that previously collected data, instrument diagnostics, and other parameters recorded up to the time of power outage are retained.

After each data file has been closed (every 15 minutes) it is moved to an archive directory, and a new file is started in the original location. The archive directory is C:\Picarro\G2000\Log\Archive\ and has subdirectories DataLog_Mailbox, DataLog_Private and EventLogs with files arranged by year\month\day\hour.
Page 38
The current data file can be found in C:\Picarro\G2000\Log\DataLogger\. Within this directory, there are subdirectories for DataLog_Private, DataLog_User and DataLog_User_Sync (only populated if evenly spaced data is supported). Similarly, the archive directory has subdirectories arranged by file type. The subdirectories are further organized by \[year]\[month]\[day]\[hour].

11. EXTERNAL VALVE SEQUENCER The Picarro valve sequencer window appears as in Figure 1 below: Figure 1 - Layout of the Picarro valve sequencer Introduction The Picarro analyzer can control two types of valves: • Solenoid valve(s): DC voltage powered valve with normally open (NO) and normally closed (NC) positions.
Page 41
Default Configuration For all models of Picarro analyzers the rotary valve control is disabled in the factory default setting. The solenoid valve control, however, are ready to use by default for all solenoid valve connectors. Setting Up Solenoid Valves Up to six solenoid valves can be controlled by the Valve Sequencer software.
