’Bound'the'Gock HPLC: Development and

Ternary gradient capability, automatic sample injection, programmable chromatographic parameter changes, a dual-channel data system, and printer/plotter output make SP 8000 the first

truly automatic HPLC.

Cut methods development time by up to 75%. LC methods development calls for the

systematic changing of chromatographic conditions: temperature, flow rate, mobile phase composition and other variables. SP 8000, by means of its microprocessor and keyboard programming, is the first HPLC to control all these things automatically. Faster, more complete separations. HPLC has always been viewed as potentially more powerful than GC because its mobile phase is an active partner in the separation process. Now recent work has shown that different solvent ratios in ternary mobile phases produce markedly different separations. For example: the selectivity of a

reversed-phase column can be changed by varying the ratio of water, methanol, and acetonitrile. SP 8000, with its microprocessor-controlled, threesolvent, single-pump gradient system, puts this added separation power at your command. Improved quantitative results and finished reports. SP 8000’s powerful dual-channel data system provides extensive report formatting and post-run calculation capabilities. Its functions include internal/ external standardization and normalization; multi-level calibration; bracketing; statistical analyses; molecular weight distribution; and simultaneous dual-detector analysis, all recorded on a built-in printer/plotter. It’s the kind of advanced system you’d expect to get

from the company that invented the computing integrator. There’s a configuration for your laboratory. Within its basic 33-inch-wide cabinet, SP 8000 can be configured in a variety of ways to fill a specific need and a specific budget. Options include an oven, a gradient programmer, a data system, an autosampler, detectors, and columns. It’s the most advanced modular design of any HPLC. Drop us a line for details. We’ll be happy to show you how you can do ’round-the-clock HPLC.
