IN CHROMATOGRAM ANALYSES . . . Reduce calculation time 10 to 1, eliminate human errors with ._—^-
INFOTRONICS CRS-1 Digital Chromatograph Integrator Labor-saving, automatic and accurate, the CRS-1 Digital Integrator accepts the output signal of any common gas chromatograph and converts it to digital values of both retention time and relative area. Peak retention times and peak areas are then recorded simultaneously in any of the com mon formats: digital printer or typewriter, punched IBM cards, punched paper tape, or magnetic tape using the Infotronics R-l Digital Magnetic Recorder. FEATURES AND SPECIFICATIONS 1. CRS-1 automatically resolves " s i d e " or partial peaks into separate areas. 2. High speed integration response — will process peaks spaced as closely as 1.5 seconds. 3. High resolution — 10,000 counts per second give maximum area accuracy. 4. Automatic area totalizing. 5. Works equally well with either ioniza tion or thermal conductivity detectors. 6. Optional input selector switch allows you to switch CRS-1 to five different chromatographs. 7. Output data compatible with computer. Input: Full scale ranges—50 mv standard or 1 mv with preamplifier. Output: linear to 100% overload on input. Integrator: Six digits standard. Accuracy: 0 . 1 % of full scale maximum error in integration conversion. No errors in counting per se. Transistorized control circuit: Maximum threshold sensitivity to rate of change of detector signal is better than 15 micro volts/second, or 1 microvolt/second with preamplifier. f o r complete information, and a list of satisfied users, ^^^^ p/ease contact ^^^
