How to introduce standards to sorbent tubes using the CSLR

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.
