This is what the future looks like in HPLC: Memory stores up to nine complete methods. Interactive CRT guides, prompts and displays — conditions. Makes operation simple. One simple CRT/keyboard controls entire HPLC system. There is a display for each major instrument function: Pump, Detectors, Scanning, Time-Relays, AutoSampler, Column Temperature, and Status. The Status display, presents a real-time readout of all operating conditions. Chromatography keyboard. Each parameter has its own key. No computer jargon. One keystroke calls up C R T for each function. Proven reliable pump and hydraulics design eliminates inlet check valve failures. No need to degas. Microstepped control provides precise, accurate flow rates for all modes: conventional, fast, semiprep and microbore HPLC. Solvent proportioning for binary and ternary gradients is microprocessor controlled for precision and accuracy. Any number of multilinear gradients can be created to handle the most difficult separation. Convenient, enclosed, ventilated solvent compartment lets you use the standard bottles your solvent comes in as reservoirs. Saves time. Improves results.
The new Varian 5 5 0 0 Liquid < T h e new Varian 5500 Series offers more capability, and more potential for future growth, than any other liquid chromatograph. To create it we took all the proven best from the 5000 Series, included all the newest L C advances and added many capabilities that are only beginning to be explored. Advanced performance features include: 1 Reproducible microstepped flow rates " Fully integrated, intelligent control ' Programmable UV-Vis detection -with scanning 1 Microbore, ultra-fast and semiprep options ' Structured, upgradable software • Complete stand-alone automation with built-in AutoSampler
Reliable, reproducible microstepped flow rates T h e entire 5500 system is built to give you reliable, repeatable performance. T h e heart of it is the patented, single-pump ternary solvent system proven for reliability in the 5000 Series. A significant difference is the new microstep control that produces even smoother flow rates and gradients at higher pressures. It also allows the very slow flow rates you need for microbore L C . Completely integrated for best synchronization of analysis actions T h e 5500 is fully integrated both physically and operationally. Injectors, p u m p , detectors, column heaters, external events and serial communications are built in. Their operation and automation are controlled by a single method and clock for better reproducibility.
Integrated AutoSampler. Methods you set up in the 5500 control reproducible injections which can be automatically handled by different methods. Choice of excellent injectors: manual loop valve, automatic loop valve, and AutoSampler. Optional injectors available for microbore and fast LC Choose any detector. Five excellent Varian detectors are offered: the built-in UV-200, UV-1 and UV-5, and the RI and Fluorichrom detectors. UV-200 time-programmable UV-Vis (190 to 700nm) detector with scanning allows optimal detection of all components. You can also program baseline zeroing and attenuation. Programmable scanning in the UV-200 helps you determine the best wavelengths for detection. Large, accessible column/heater/detector compartment accepts 15 to 50 cm columns with or without heaters and allows installation of two detectors as shown here (UV-200 and UV-5) for dual wavelength detection and ratioing. Column temperature control. For total automation, including data handling, the 5500 combines with VISTA 402 to form the VISTA 55 Automated Liquid Chromatograph. Saves space. Entire system as shown here, takes only 31 inches counterspace. Less than most component systems.
romatograph Simple, one-keyboard control This synchronous, time-programmed control of all analysis components is through a single C R T and keyboard that simplifies operation. Stand-alone automation For completely automatic overnight operation, an AutoSampler can be added. T h e n methods set u p in the 5500, and stored in its nine-method memory, will control injection and analysis of u p to sixty samples. Choice of 5500 configurations Although fully integrated, the 5500 is modular. So, you can choose the best combination of injectors, detectors,
heaters, columns and accessories for your specific needs. Even the software is structured for easy updating. For full details, circle R e a d e r Service N u m b e r 2 2 3 .
