Auto Sampler
|
 |
The PII-AS-42 (Autosampler) accessory is now available for delivery. The autosampler incorporates our standard flow through Raman sample cell and uses an InPhotonics Raman probe to optically connect the laboratory accessory to our PI-200-L (Laboratory) Raman spectrograph. The accessory can hold up to 42 sample bottles (40 ml volume) with open lids and Silicone/PTFE (0.090"/0.010" thick) septa seals to ensure that volatiles remain in the sample during testing. Typical flush times are ~ 30 seconds. The user can load a mixture of different types of samples and PROspectTM software automatically loads the appropriate chemometric models to predict the correct parameters. Prior to starting a batch of sample, a performance check is made to ensure the system is operating properly and when the batch is completed a cleaning cycle is run to maintain optimum sampling performance. Raman spectra and predictions are stored and also made available in a LIMS report format. The autosampler is designed to handle most liquids including aqueous samples, gasoline, jet fuel, and diesel oil type products.

The Sample Handling System comes with a automated/manually operated, variable speed pump controller and sample interface flow cell. The pump comes with a 316 SS, magnetically-coupled pump head capable of flow rates from 5 to 90 cc/min. Flow cells are constructed from 316 SS and accept 1/8" standard tubing (larger size tubing fittings available) through 316 SS SwagelokTM o-ring face seal inflow and outflow connectors. Flow cell design directs sample stream to continually clean the Raman Probe interface minimizing cell maintenance and cleaning. The flow cell can accommodate operating pressures > 250 psi and flow rates from 5 cc/min to over 100 cc/min.
