The Nester/Faust 1240 introduces a new concept in high speed analytical liquid chromatography . . . a complete and self-contained precision instrument with features and capabilities that, until now, were only available on more complex and more costly units. To make our point, let's look at the 1240's outstanding features, one by one. First, easy operation and reproducible analyses are due, principally, to an adjustable 1,000 psi pump, with continuous degassing of solvent, and a zero dead-volume, zero back pressure pulse damper. Second, for gradient elution analysis, there's a precision gradient former available. Third, separation is enhanced by a standard, ambient to 125°C forced air oven with nitrogen purge. Fourth, fountain effect is eliminated by the zero dead-volume oncolumn septum injector. Fifth, we assure highest resolu-
tion by designing and manufacturing all our own columns and fittings. Sixth, the 1240 unit is supplied with a 2000 psi, 12 ul U.V. detector, with internal calibration. Ultimate detector sensitivity is 0.0002 O.D. units. In addition, a complete line of column packings is available. All of these features, plus more that we don't have room to discuss here, add up to some of the reasons why the 1240 is a unique analytical L.C. base priced at $4,900 . . . but don't let the price fool you, we haven't sacrificed quality anywhere in this instrument.
