Column Selection

Choose from our selection of Restek Siltek®-treated stainless steel MXT® GC columns. MXT columns eliminate GC column breakage at high temperatures; stable up to 450 °C. Exclusive Siltek® treatment produces exceptional inertness and more accurate data.

 

All columns are packaged in the miniGC EasySwap column holder.
NO more ferrules, nuts, tools or headaches!

Calibration Standards

Make sure your miniGC is working properly by injecting one of our Restek calibration standards and running the associated method. The system will let you know if it is operating properly based on a comparison of the obtained results to the expected results. All miniGC’s are calibrated in production using one of these standards and can be performance checked at any time using one of these standards.

Gas Filters

To enhance performance of the miniGC, make sure you are running clean gasses. Attach inline gas traps to each of your 3 inlet gasses to ensure optimized performance.

 

The R22457 kit includes one gas trap and fittings for your carrier gas, Helium.

 

The R22461 kit includes two gas traps and fittings for your FID gases, Hydrogen and Air.

 

The traps are placed on each of the 3 inlet gas lines before they connect into the miniGC system to ensure that you have super pure gas going into the system, which will improve your results.
