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. P/N 40017-Rev E G2205 Analyzer User Manual...
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.
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...

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. G2205 Analyzer User Manual P/N 40017-Rev E...

Figure 2 - Layout of the Picarro analyzer GUI, G2000 series. A full explanation of the GUI functions can be found in Section 10 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.

The Picarro valve sequencer window appears as below: External Valve Sequencer GUI C.1 Introduction The Picarro analyzer can control two types of valves: 1. Solenoid valve(s): DC voltage powered valve with normally open (NO) and normally closed (NC) positions. These can be either 2-way or 3- way valves.
C.2 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. C.3 Setting up Solenoid Valves Up to six solenoid valves can be controlled by the Valve Sequencer software.
Each “step” sets the rotary valve to a single position and activates the indicated solenoid valve(s) for a set period of time. Multiple steps can be carried out in sequential order to switch between different gas sources, G2205 Analyzer User Manual P/N 40017-Rev E...
