How to introduce gas standards to complement liquid standards using the CSLR

How to introduce gas standards to complement liquid standards using the Calibration Solution Loading Rig (CSLR). For more information visit
The Calibration Solution Loading Rig (CSLR) has been specifically designed for loading sorbent tubes with gas- or liquid-phase standards. It has a flow-path constructed of stainless steel and consists of an unheated injector port with a controlled carrier gas supply. The sampling end of a packed sorbent tube is connected to the CSLR by a ¼-inch brass nut and PTFE ferrule.
The carrier gas flow is adjusted using a needle valve, and is normally set between 50 and 100 mL/min. The calibration standard (gas or liquid phase) is introduced through the injector septum using a precision syringe, and onto the sampling end of the attached tube.
