Raptor™ Biphenyl LC Column by Restek Corp.

"These columns are by far the best I have used. They are very easily installed and produce high quality chromatographs on our 3200 LC/MS/MS. The lifespan of these columns is amazing. Columns are our most expensive consumable, but far and away we are able to inject more samples with this column compared to other brands."

"Our laboratory has been using the Raptor Biphenyl LC Column for over 5 years now with minimal to no problems. Easy to change and reproduces consistent results day after day. Very happy with Restek services and products."

"I love the raptor column, they are rugged, efficient, and with proper care and use, can last a long time. They are perfect for separation of drugs and metabolites and are easy to install and condition on the rare day that its lifetime ends. Their long lasting nature makes life easy as they provide value per unit and decrease downtime, since I do not need to condition a new column every other month."

"This product provides reliable chromatography results, and is easy to connect and use. Resolution is excellent."

"After speaking to Raptor experts at Thames Restek we agreed on a evaluation period for the Raptor Biphenyl column for HPLC analysis of small molecules. The service they provided was excellent and they have offered after care support, allocating meetings at our place of work."

"This column has been a very useful alternative to C18 columns for the separation of polar compounds and difficult to separate isomers. So far the results have been reproducible and we haven't encountered any problems using this column."

"We are currently building a repertoire of columns to use in SFC for multiple applications. We've had some success with separating PAH & metabolites using the 150 mm x 4.6 mm x 2.7 u Raptor Biphenyl column, as well as fat soluble vitamins. This column allows us to operate at high flow rates for fast separations. Excellent customer service!"

"As promised, this column does a better job of resolving our analytes (antipsychotic drugs) from matrix constituents (post-mortem - decomposed - bone tissue extracts) than the traditional C18 chemistry we were using. We are using PDA detection, where chromatographic resolution is much more critical than with MS detection. As a result we are using the 150 mm x 2.1 mm column (1.7 um) particle size."

"This offers an interesting alternative to C18 and complex mobile phases for some difficult separations. It appears to have advantages over phenyl-hexyl, and with more experience, I may use the Raptor as my generic phase of first choice. It has good efficiency, allowing the possibility of shorter run times. It is well worth investigating for troublesome applications."
