Source: GS-Tek stationary phase cross-reference PDF. All trademarks and product names are the property of their respective owners. Cross-reference information is provided for product comparison and identification only. It is not a guarantee of identical performance; final column performance may depend on dimensions, stationary phase chemistry, deactivation, inertness, temperature limits, analytes and method conditions.

Frequently Asked Questions

Can GS-Tek help find an alternative to an Agilent DB or HP GC column?

Yes. This cross-reference lists common Agilent DB, HP and PLOT column phase names next to related GS-Tek phase families. Confirm the final choice against your method, column dimensions, temperature limits and analytes.

Can GS-Tek help compare Restek Rtx or Rxi GC column phases?

Yes. Search terms such as Rtx-5MS, Rxi-5ms, Rtx-624, Rtx-1701, Stabilwax and Rt-QPLOT can be used as starting points for GS-Tek phase review.

Is a cross-reference GC column a guaranteed drop-in replacement?

No. Similar stationary phase chemistry is a starting point for method transfer. Performance can depend on film thickness, internal diameter, length, inertness, deactivation, instrument configuration and method conditions.

What information should I send for a GC column equivalency request?

Send the current manufacturer, phase name, part number, dimensions, application, analytes, instrument model, detector and quantity. A chromatogram or method name is helpful when available.
