Highly recommended column for oxygenated C3 analysis.
Rating: 4.7

  • Application Area: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."

It is a tremendous tool for GC separations. Very reliable.
Rating: 5.0

  • 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.
Rating: 5.0

"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."

Great peak shape and selectivity for broad range of compounds
Rating: 5.0

  • Application Area:Wide range of polar and non-polar analytes for pharmaceutical process development

"These columns are amazing. I am impressed with the peak shapes for the wide range of polar to non-polar analytes, even basic compounds. I also like the higher temperature maximum when compared to classical phases. I use this column on FID as well as MS with great success."
