The Rxi-624 Sil MS column is great for terpenes analysis in cannabis products.

 

Average Rating 3.0

Application Area:

Analyzing terpenes and residual solvents on cannabis products

The product achieves high quality and reproducible results.

Review Date: 23 Jul 2021 | Restek Corp.

Love it! Would not go back to my old column.

 

Average Rating 5.0

Application Area:

VOC Analysis

Great column. Can go to higher temperatures which is always good.

Review Date: 14 May 2021 | Restek Corp.

This column is the heart of my GC separations.

 

Average Rating 5.0

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.

Review Date: 16 Jul 2020 | Restek Corp.

Very great product, thank you.

 

Average Rating 5.0

Application Area:

Determination of API and its metabolites in biological fluids and materials

Very effective product. Always use in my research laboratory. I advise using these products to my colleagues.

Review Date: 10 Dec 2019 | Restek Corp.

Highly recommended column for oxygenated C3 analysis.

 

Average 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.

Review Date: 10 Dec 2019 | Restek Corp.

It is a tremendous tool for GC separations. Very reliable.

 

Average 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.

Review Date: 9 Dec 2019 | Restek Corp.

Excellent resolution and performance.

 

Average Rating 5.0

Application Area:

Quantification of cannabis native terpenes and residual solvents

Excellent resolution for the quantification of cannabis native terpenes and for the detection of residual solvents using HS-GC/FID Agilent 6890.

Review Date: 6 Nov 2019 | Restek Corp.

Excellent for cannabis terpenes quality control assays.

 

Average Rating 5.0

Application Area:

Analyze residual solvents and cannabis terpenes

This product provides suitable resolution for the analysis of cannabis terpenes assays and residual solvent tests in the ahilent 6890 GC/FID.

Review Date: 3 Oct 2019 | Restek Corp.

Good resolutions and better result of tailing.

 

Average Rating 5.0

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.
