Description
The Ascentis family of columns is the fourth generation of HPLC column technology from Supelco scientists. Ascentis columns are bonded on high purity, 100 Angstrom silica including 3, 5, and 10 micron particle size. Columns are designed for small molecule applications and are scalable from micro columns (1.0 mm I.D.) to preparative dimensions (50 mm I.D.). The family includes C18, C8, Phenyl, Si and embedded polar group phase, RP-Amide.
The Ascentis C8 is a highly reproducible column with excellent selectivity towards polar compounds. The phase excells in highly aqueous mobile phases as well as high organic mobile phases.

"In my opinion this column is good value for money, it’s stable with reproducible results." |

"Very robust. When some other brand name UHPLC columns have retention time shift issues with our agricultural samples, the ones we got from Sigma do not. Although the resolution might not be as high as the 1.7 micro ones." |

"When working in a QA/QC lab, reproducibility and precision are critical. To control the number of variables we only use Sigma-Aldrich columns. Their columns proved to give the best results during our column validation studies. For our application their columns are durable, reliable from batch to batch and reasonably priced. I would recommend this column to any looking to run the same application continuously. (We don't do much method development so I can't comment on how well they would work at separating unknowns.)" |
