All 207 variations of our new Moduline 2800 Series GC fit here.
At last count, we came up with 207 dif ferent versions of our new 2800 Series Gas Chromatograph. Each able to do a very specific GC job reliably well. With remark MULTILINEAR TEMPERATURE able reproducibility. PROGRAMMER Built around a truly modular mainframe (left), the entire 2800 Series shares an impressive list of standard features. Among them are a newly redesigned electrical system that's not only compatible with any commonly used voltage in the world, but which also produces the cleanest signal ever to come out of a GC. A unique all solid state dual/differential electrometer (above right). A greatly simplified flow control system. A spacious 1090 cubic inch column oven. And dual column, dual detector capability. But that's just the beginning. You can choose from four different temperature programmers, plus four versions of our computer-compatible Multilinear Temperature Programmer (MLTP) pictured above on the left. We currently have five detectorsfour ionization and one TC- from which a variety of combinations can be made. Significantly, all four ionization detectors fit on a common base for speed and ease of interchangeability. In the end, regardless of versatility, a GC is only as good as the results it produces.
The automobile exhaust emission analysis, below, is just one example of the tough jobs the 2800 handles with authority. This particular analysis is the result of four different capabilities working at once. Cryogenic operation. Capillary DUAL/DIFFERENTIAL capability. Multi-linear ELECTROMETER temperature programming. And computer controlled operation. The results speak for themselves. (We might also note that in 18 runs of similar samples over a period of 48 hours, the worst cumulative retention time error was less than two seconds over a retention time of 1100 seconds.) We've published a booklet detailing all 207 variations of the new Moduline 2800 Series GC. For your copy, simply write on your letterhead to Varian Aerograph, Walnut Creek, California 94598 ; Tokyo, Japan ; Malton, Ontario, Canada; Crows Nest, N.W S., Australia; or Zug, Switzerland. And, if you find 207 combinations aren't enough, we'll be glad to sit down with you and work out Number 208.
