Series 200 LC-Pump

The series 200 LC Pump

The Perkin-Elmer Series 200 LC Pump can be used with virtually every LC system or appli­cation. The Series 200 LC Pump is upgradable from a single solvent (isocratic) pump, to mix­ing two solvents (binary) or to mixing four solvents (quaternary). In addition, each version is available in a biocompatable version. The Series 200 LC Pump provides you with the inter­changeable technology so that you do not have to buy a new pump and learn new user inter­faces every time your needs change.

Series 200 LC Pump Features and Benefits

•     Upgradable isocratic, binary, and quaternary versions as well as biocompatible versions for maximum flexibility.

•     Small, compact design (12 inches (30.5 cm) wide) saves valuable bench space.

•     Directory of up to 20 methods, 20 steps each with built-in method linking increases sam­ple throughput.

•     Edit the active method or sequence in real-time with easy access function keys.

•     Large backlit liquid crystal display allows clear viewing of pump method and operating parameters at all times.

•     Unique function allows automatic shutdown of the pump method at final gradient method.

•     Graphic display of solvent profile on-screen shows real-time status of the gradient method.

•     Hold gradients or advance to the next step with a simple keystroke.

•     Solvent-resistant front panel with rounded ergonomic design for easier interaction with the keypad.

•     Tactile keyboard with unique "key click" so that you know your entry has been made.

•     Phone-type contact closure connections and finger tight plumbing Fittings make it simple to connect or disconnect your system.

•     Full method documentation including modification with method name, number, date and time stamp.

•     Visual access front-door panel allows quick plumbing inspection and easy servicing.

•     Maintenance log coded by the serial number of the pump, including pump and seal cycles.

•     Instrument log records history of operation for quick diagnosis and servicing to get you up and running quickly.

•     Extensive service diagnostics.

•     Pump module can be completely removed to lab bench for maintenance without having to unstack modules.

Series 200 Autosampler

Figure 1-1. The Series 200 LC Autosampler.

The Perkin-Elmer Series 200 LC Autosampler is an advanced sample processor that can be used with virtually every liquid chromatography system or application. You configure the Autosampler and define all of your methods and operations using function keys on a key­board located on the front panel of the instrument. A backlit Liquid Crystal Display (LCD) located directly above the keyboard shows both status information about the instrument and provides access to the screens you use to define methods and set configuration parameters. If you use the Perkin-Elmer Series 200 LC Pump, you will find that the Autosampler front panel is almost identical to the one on the Pump. In addition, the Pump and the Autosam­pler share many common operating features that will allow you to get your system up and running quickly. The Series 200 LC Autosampler provides you with interchangeable technol­ogy so that you do not have to buy a new Autosampler and learn new user interfaces every time your needs change.

Series 200 LC Autosampler Features and Benefits

•     Upgradable to biocompatible versions for maximum flexibility.

•     Small, compact design (12.5 inches (31.8 cm) wide) saves valuable bench space.

•     Directory of up to 20 methods.

•     Ability to link up to 10 methods together in a sequence.

•     Priority method which allows you to interrupt a method or sequence to run critical sam­ples. The method or sequence resumes once the priority samples are analyzed.

•     Edit the active method or sequence in real-time with easy access function keys.

•     Large backlit liquid crystal display allows clear viewing of autosampler method and operating parameters at all times.

•     Tactile keyboard with unique "key click" so that you know your entry has been made.

•     Phone type contact closure connections and finger tight plumbing fittings make it simple to connect or disconnect your system.

•     Full method documentation including modification with method name, number, date and time stamp.

•     Visual access front-door panel allows quick plumbing inspection and easy servicing.

•     Maintenance log coded by the serial number of the autosampler, including autosampler injection cycles.

•     Instrument log records history of operation for quick diagnosis and servicing to get you up and running quickly.

•     Extensive service diagnostics.

•     Sampler module can be completely removed to lab bench for maintenance without having to unstack modules.

DAD-Detector LC-235C

The LC-135C and LC-235C multiple wavelength diode array LC detectors contain the following features:

•     Individual signal amplification of each pixel for a significantly improved signal-to-noise ratio.

•     Automatically determines peak purity by an absorbance index technique, for dependable data, even on trace levels of sample.

• A dual beam design using two 35-element diode arrays pro­vides excellent baseline stability at all wavelengths and all sol­vent systems.

•     History File reports (records of detector conditions for the run) are printed at the end of each run.

•     Automatically annotates the wavelength of maximum absorbance on each peak.

•     Biocompatible solvent path.

•     Instantaneous wavelength change.

•     All wavelengths monitored at the same time.

•     Computerized diagnostics.

     In addition, the LC-235C Diode Array Detector contains the following features:

•     Produces instantaneous spectra.

•     Plots the spectra.

•     Overlays the spectra.

•     Normalizes the spectra.

•     Constructs an Absorbance Profile Map.

•     Contains the option of selectable modes of spectral acquisition.

•     Produces automated background correction of spectra.
