The Buck Automatic Calibration System (ACS) is especially designed for TO-14 air monitoring. When the TO-14 air concentrator is used with a Buck GC, the system allows an automatic recalibration.
The GC includes a PeakSimple software in its package which is used with the ACS. Under the control of this software, the ACS can make dilutions of the user-supplied standard gas and Zero Air at ratios of 10,000 to 1. A diluted gas which is produced by this process is sampled into the TO-14 Air Concentrator by a vacuum pump which is supplied with the TO-14 Air Concentrator. When both the EPC pressure and time are calibrated according to specific requirements, the 100ppm standard can be diluted over a 10,000 to 1 concentration.
