Gas Chromatograph

Recording Data Processor

GC-MIIMI2

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.

This surprisingly light weight, compact GC system has the performances of much larger more expensive systems. Dual column flow and on-column/on-detector system ensure excellent stability, high sensitivity, and perfect accuracy. Flow rates and pressures of the gases can be easily measured using one-touch connectors and flow monitors in the gas flow lines. Unique oven temperature control system maintains the oven at room temperature, even when the injection port temperature is high. Contamination-free 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.
