PicarroSI2205Gas concentration analyzer canpptLevel sensitivity to hydrogen fluoride(HF)Real time and drift free measurement of concentration. This analyzer is based onPicarroUnique cavity ring down spectroscopy technology(CRDS)Developed to use near-infrared lasers to measure the spectral characteristics of molecules for time-based measurements. Gas circulates in the optical cavity, with an effective optical path length of up to20 kmThe patented high-precision wavelength monitor ensures that the analyzer only monitors the spectral features of interest, greatly reducing the sensitivity of the analyzer to interfering gas components, and can measure ultra trace gas concentrations even in the presence of other gases. Therefore, the analyzer only requires minimal calibration work to maintain high linearity, accuracy, and precision under constantly changing environmental conditions.Picarro SI2205There is a precise chamber temperature and gas pressure control system inside, which can ensure measurement accuracy for a long time while minimizing the use of calibration gases. This analyzer is easy to use, sturdy, virtually drift free, maintenance free, and requires almost no consumables. Therefore, the device has excellent usability and effectively reduces the cost of subsequent long-term measurements.
This analyzer can be easily transported between stations, set up and put into operation within minutes, and does not require any sample preparation. Its built-in valve sequencer software can control up to6An external solenoid valve and1A rotary valve. The gas concentration can be displayed in real-time without post-processing, and the measurement data can be automatically and continuously archived to the internal hard drive of the analyzer. This analyzer is designed to operate in laboratories or harsh environments and can run for months without user interaction. This analyzer can be configured through EthernetRS-232InterfaceAnalog 4-20mAperhapsModbusAutomatically export measurement data using other methods. Users can remotely connect to the analyzer through standard remote desktop connections or by using similar remote login softwareLinuxSystem.
