This column is the heart of my GC separations.
Application Area: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."

It is a tremendous tool for GC separations. Very reliable.
Application Area: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.
Application Area: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."
