These column nuts are replacements for damaged or misplaced original Agilent/HP MSD nuts. They are to be used with the longer design ferrules for Agilent/HP GC′s.
With our Make-up Gas Detector Adapter Kit you can use the capillary column at optimum flow rates (2-10mL/minute), even if your detector is designed for higher flows. You can connect the column and a make-up gas line (to prevent column effluent from spreading in the detector) to the detector without modifying your detector gas line. Regulate the make-up gas through external control (see diagram) or, in a two-column instrument, connect the make-up gas line to the second injection port and regulate flow with the flow controller (requires a Swagelok reducer � Cat. No. 22017-U for a 1/8 in. fitting, Cat. No. 22701 for a 1/4 in. fitting � and nut; order separately).
