If your chromatograph was made on Mars by Triffids you could still use Partisil columns. Partisil HPLC columns fit every liquid chromatograph made. All eight kinds of them are available with any of thirteen "standard" end fittings plus the backing of a library of "special" designs. Couldn't be simpler — specify the fittings code for your LC and, voila!, a Partisil column is delivered that fits your liquid chromatograph perfectly. And that's how it is, regardless of the make or model of your instrument. Partisil columns for: Altex, Chromatec, Chromatem, Chromatronix, Du Pont, Glenco, Hewlett Packard, Hupe and Busch, ISCO, Knauer, LDC, Micrdmeritics, Perkin-Elmer, Pye Unicam, Siemens, Spectra Physics, Tracor, Varian, Waters; Rheodyne and Valco (and Whatman) injectors. . .

We've fitted Partisil columns to "component" systems that are — ah — unusual, and to every kind of instrument offered commercially. It's just as easy to use a Partisil column — made by people who specialize in columns, not instruments — as the column your instrument maker supplies. And, of course, Partisil performance comes with every column. We're not exactly soliciting orders from Mars, of course. But if one comes in we'll accept it. And the Partisil columns will fit. Perfectly. Partisil is a Trademark of Whatman Ltd.
