Common Questions and Answers

We get several great questions whenever we go out to trade shows – we figured now would be a good time to post some of those questions and our answers:
Q: Have you really been manufacturing Thin Layer Chromatography plates and equipment longer than anyone else in the world?


A: Yes, we’ve been doing this since 1961 – next year we celebrate 50 years of supplying the world with high-quality Chromatography products.
Q: What’s so special about your Chromatography supplies?
A: Glad you asked! We offer the following:
  • Glass-Backed, Pre-Scored plates
  • Aluminum-backed layers
  • Plastic-Backed layers
  • Florescent Indicators
  • Solid Phase Extraction (SPE) SPICE Cartridges
  • Bulk Absorbents
  • HPLC columns 
Q: We noticed that you have very colorful HPLC Columns, is there anything else we should know about them?color HPLC columns
A: Yes, besides the practical aspect of knowing which packing 

color columns

material you have inside a column based on the color outside, our HPLC columns utilize proprietary bonding technologies from Separation Methods Technologies that result in bonded phase coverage approaching 100%.
Q: Tell us more about the Cyclograph – can it really separate up to 4 grams of sample in 20 minutes? and can we see a demonstration of how it works?
A: Excellent question! The CycloGraph system is a centrifugally accelerated device for performing preparative thin layer radial separations. The separations occur quickly (normally within 20 minutes) with no need for scraping separated bands as with traditional Thin Layer Chromatography. Here’s a video demonstration, and you can click here for more information.

Q: Can we order your products direct or can we go through a distributor?
A: Yes, you can order directly from us or you can work with any of our distributors (we work with several – all around the world) – click here for more information.
