The Gas Calibration Unit (GCU) provides variable but known quantities of different standard compounds in the carrier gas stream, allowing accurate calibration. The GCU system is a stand-alone device that can be used with many different VOC analytical instruments, but it is particularly suitable for PTR-MS systems, providing semi-automatic calibration.
