LPG Autosampler

The LPG autosampler incorporates our standard flow through Raman sample cell and uses a standard laboratory Raman probe to optically connect the laboratory accessory to our PI-200-L (Laboratory) Raman spectrograph. The accessory can hold up to 6 sample cylinders. Double block/bleed valves with minimal dead space and complete flushing of the lines post spectrum acquisition are some of the methods used to ensure there is no cross-contamination between different cylinders. Typical flush times are ~ 20 seconds. The user can load a mixture of different types of samples, and our PROspect software automatically loads the appropriate chemometric models to predict the correct parameters. Prior to starting a batch of samples, a performance check is made to ensure the system is operating properly, and the instrument automatically detects error conditions, i.e., no sample present, low sample bomb pressure, or low air pressure powering pneumatic valves. Raman spectra and predictions are stored and also made available in a LIMS report format. The LPG autosampling system is designed to handle most LPG-type products.
