Three smart reasons to choose J&W. Great chemistry. The results you get out of a column depend on the chemistry you put in—polymer chemistry, that is. Polymers are the basis of all GC, HPLC and SPE phases. That's why J&W has a team of Ph.D. chemists who specialize in novel polymer synthesis, from silane building blocks to unique surface chemistries. Their ingenuity made J&W a world leader in gas chromatography. Now, that same expertise is applied to our new Accusphere™ HPLG columns and Accubond™ SPE cartridges. Remember, chromatography begins at the molecular level—long before pumps and detectors. So if you're working with HPLC or GC. give J&W a call. It could be the smartest move you'll ever make. Reliability. J&W chemists control every detail of the manufacturing process, from the very start. They synthesize the phases that bond to HPLC and SPE silica, and the silanes that make up each GC
stationary phase. This ensures a high level of consistency, with excellent batch-to-batch reproducibility. Our QC technicians personally test and guarantee every column we sell. You can depend on J&W for the very best —both in our products, and your results. Convenience. J&W is your central source for GC and HPLC columns and SPE cartridges. All our products are optimized for performance. And when you have questions, there's just one place to call for technical support and applications advice. Chemistry Reliability. Convenience. Three smart reasons to choose J&W for columns and cartridges. There . are dozens more. Send for our 1990-91 catalog and find out for yourself. It's free. Which may be the best reason of all.
