Love it! Would not go back to my old column.
VOC Analysis
Great column. Can go to higher temperatures which is always good.

This column is the heart of my GC separations.
Pharmaceutical drug substances analysis
A very rugged column with good reproducibility of retention/results and low bleed even at very high temperature. Life of thease columns is very good. I found that column to column variability is very low. The cost of the column is a little bit high but worth buying.

Highly recommended column for oxygenated C3 analysis.
Analysis of oxygenated C3 products
Excellent column for the analysis of lower alcohols and oxygenated C3 products. Additionally, one of the few columns to go up to temperatures of 300°C and at the same time provide the desired separation.
Review Date: 10 Dec 2019 | Restek Corp.
It is a tremendous tool for GC separations. Very reliable.
Pharmaceuticals
Basically, the separation of USP Class II residual solvents acetonitrile and methylene chloride is fantastic - always higher than 1.5, going up to a 2.1 resolution. The column is tough and very durable. Currently, I have a column of about 6 years, and it is still up and running. I have used this column in different GC's and always get the same good results.

Good resolutions and better result of tailing.
Analyze medicines
Excellent GC columns. Midpolarity crossbond phase. Low-bleed, high-thermal stability column—maximum temperatures up to 300–320 °C. Inert—excellent peak shape for a wide range of compounds. Selective—G43 phase highly selective for volatile organics and residual solvents, great choice for USP. Manufactured for column-to-column reproducibility—well suited for validated methods.
