Interview with Jeff Caldwell, President, Princeton Chromatography, Inc.
You know when you get that Kromasil® bottle with the blue cap that it’s going to be right
The team at Princeton Chromatography has more than 20 years of experience working with our Kromasil products and we have reached out to Jeff Caldwell to learn more about what is important to them and their customers in the pharmaceutical industry.
“It is a very consistent material. You can go from lot to lot and get a consistent product out on the other side. The high-quality standards and consistent specifications over time are super important to our customers,” says Jeff.
“The efficiency of Kromasil is also really good. We have a project ongoing right now and we evaluated three different silica materials for a client. In a straight up comparison, same exact procedure, same amounts, same everything, Kromasil worked the best so we decided to go with that, “he continues.
Would you recommend Kromasil for large scale-up?
“Absolutely! The material is really consistent over the whole range of particle sizes for a particular pore size and that really lends itself to scale up. You do not have to guess; it takes the guessing out, at least in my experience. You can just go from your analytical system, to prep to large scale. Buy the material, pack your DAC, and off you go.”
Princeton Chromatography was founded by Jeffs father Walt Caldwell and specialize in manufacturing phases for SFC, but also reversed-phase and normal-phase HPLC.
“After 24 years at Merck, my dad decided to start his own company in 1994, and I took over in 2009” Jeff adds.
Do you have any final comments?
“I really can rely on the material, and you know when you get that Kromasil bottle with the blue cap that it’s going to be right. I can just look at the sheet and make sure it matches, scan the CoA into our system and off we go. So that makes my life easy” he concludes.
