CORTECS® Columns by Waters

"The column is reproducible and long-lasting. I got good peak shape and good separations using this column. Thanks Waters."

"Great baseline with perfect separation for mobile component separations. Useful with impurity & stability MD."

"The CORTECS range are now the go to columns for UPLC application in our lab. Improved resolution and sensitivity over anything we have seen so far. Robust as well making for value for money"

"The Cortecs C18 (1.6 µm) was an excellent choice for my UHPLC RP method covering a wide range of drugs and metabolites. Good separation and peak shape!"

"This column provides excellent and reproducible LC-MS chromatogram for my glycosphingolipids analysis. In addition, I am getting very narrow peaks which increases my peak capacity. This could be due to the very small particles (1.6 um) and core-shell type silica particles it has."

"Needed to develop a RP UV method, had one week from start to finish. I tried a few columns before I decided to contact Waters. Waters sent me a CORTECS C18 and the results was amazing. Perfect symmetry and repeatability for a method that otherwise needed more time to refine. Saved me a lot of time for this project."

"The Cortecs T3 column has provided excellent separation of mixed polarity compounds. The column, as expected, has provided excellent selectivity for moderately polar compounds. This is a great column to add to your method development screen!!"

"The column is easy to use. Good stability at high temperature and low pH, not bad batch reproducibility and relative fast column equilibration (CSH C18 little faster). We want to see next time the stability with pH 6-8. Very happy to work with the new CORTECS Columns! "

"The product is of great quality and retention time and pressure are optimal."
