Chromatopac C — R 1 A

Recording Data Processor

Other chromatograph data processors can calculate common standard calculation routines such as area normalization, normalization with response factors, external standardization and internal standardization, but only the C-R1A goes a step further and calculates calorific value, steam pressure, liquid specific gravity, deviation from a standard value, mole density (%) —weight density (%), and other factors from the results of these calculations. Other outstanding features of the C-R1A include a thermal printer plotter for chromatograms and data recording, recording of the names of components, recording of up to 339 peaks, measurement of peak-top height or average height, all-new grouping function, and self-diagnostic function. These features not only ensure fast, precise analysis, but also free the chromatographer from troublesome, time-consuming manual calculations for more important work.

G C-MINI 2 Gas Chromatograph

This surprisingly light weight, compact GC system has the performances of much larger more expensive systems. Dual column flow and on-colum on-detector system ensure excellent stability, high sensitivity, and perfect accuracy. Flow rates and pressures of the gases can be easily measured usir one-touch connectors and flow monitors in the gas flow lines. Unique oven temperature control system mainte the oven at room temperature, even when the injection port temperature is high. Contamination-fre flame ionization detector exhausts the vapor from the flame directly from the jet to a cylindrical ion collector and vent at the top. G C - M I N I 2 easily disassembles into four main modules —column oven, injection port/detector, flow control unit, and electric control unit —for quick, easy maintenance. The electric control unit further disassembles into six sub-units, thus simplifying maintenance still further.

GC-7AC3 Series Ghost-Cut Gas Chromatograph

The unique Shimadzu Ghost-Cut system sample injection port eliminates ghost peaks and baseline fluctuations caused by the substances evolved from the rubber septum and the volatile substances absorbed by the sample residue on the inner surface of the injection port. Thus, contamination of the injection port is reduced and the meantime between cleanings is lengthened, resulting in more efficient operation. This new GC also features a low heat capacity column oven to ensure rapid cooling, interchangeable columns, dependable automatic wall sensor cooling mechanism, dual column, dual.flow system, simultaneous installation of four detectors for multi-purpose versatility, constant-current type TCD with filament protection circuit, excellent TCD stability in temperature programmed GC, new FID with improved sensitivity and stability, new linear ECD with expanded dynamic range, new high-frequency induction heated FTD, automatic digital scanning display, foolproof digital temperature setting, and complete protection against temperature runaway.

GC-6AM Series Cartridge Gas Chromatograph

The GC-6AM Series is an extremely versatile gas chromatograph that lets you change your entire analysis system without time-consuming cooling of the column, injection port, and detector. Simply change cartridges and you're ready to begin a new GC run. FID, ECD, TCD (factory installed), backflush, precut, column conditioning, and capillary column cartridges designed to handle any GC application offer more versatility, flexibility, and performances than ever before.
