LGR's Hydrogen Fluoride Analyzer (HFA) provides sensitive measurements of HF in ambient air or in industrial process flows with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time to measure HF with extremely high sensitivity – LGR's HF Analyzer provides measurements every second with ppbv-level precision. In addition, the HFA can report measurements quickly over a very wide range of HF concentrations. The instrument, based on LGR's cavity enhanced laser absorption spectroscopy, is extremely simple to use, inexpensive to operate, and includes all components (internal vacuum pump, keyboard, mouse, video monitor) to start recording data within minutes. Other atmospheric gases, including water vapor, carbon dioxide, oxygen, and methane, do not interfere with the HF measurements. The instrument includes an internal computer that can store data practically indefinitely on its internal hard drive (for unattended long-term operation), and that can send real-time data to a data logger through its analog and digital (RS232 serial) outputs. In addition, an Ethernet connection allows remote access to data files stored on the instrument’s hard drive. LGR's Hydrogen Fluoride Analyzer provides the high quality data necessary for the most demanding trace gas monitoring applications.
The analyzer uses LGR’s patented Off-axis ICOS technology, the fourth-generation cavity enhanced absorption technique, which employs a high-finesse optical cavity as the measurement cell. LGR’s technology has many proven advantages over conventional first-generation cavity ringdown spectroscopy (CRDS) techniques. In brief, since the laser beam does not have to be resonantly coupled to the measurement cell (i.e. precise beam alignment is not critical), LGR Analyzers are relatively inexpensive, simple to build, and inherently robust thermally and mechanically. In addition, since LGR’s technology can record reliable absorption spectra over a far wider range of optical depths (absorbance values) compared with CRDS, LGR Analyzers provide measurements over a much wider range of mixing ratios (gas concentrations). Finally, due to the ease and simplicity of recording and quantifying the measured spectra using LGR’s Off-Axis ICOS, LGR Analyzers display the entire absorption spectra to the user in real time allowing for immediate system diagnostics and performance validation.
