The Model 203 Chromatography Data System consists of PeakSimple for Windows/Windows 95 software plus a single channel 20-bit high resolution A/D board. The 203 system can be mounted inside the Model 8610C or 310 GC, or it can be mounted in a separate box for connection to other vendor's GC or HPLC detectors. When mounted in an SRI GC, the 203 controls the temperature program of the column oven and the pressure program of the carrier gas electronic pressure controller ( EPC ). The eight available TTL outputs are connected internally within the GC to control functions such as valve rotations, gas solenoid actuation, autosampler injection, etc. When mounted in a separate box, the temperature and pressure control outputs are available for use, but not connected to anything, and the eight TTL outputs can optionally be wired to a bank of eight single-pole, dual-throw mechanical relays with screw terminals ( part# 8600-1056 ) for easy connection to any user device which operates from a contact closure. A remote start input allows run initiation from the user's GC or HPLC system. Data can be acquired at rates up to 50 Hz. Windows 95 computers with two available serial ports ( bus mouse installed ) can operate dual 203 systems, or a 203 and a 202 simultaneously. The 220 volt system is supplied with a UL, CSA, and CE/VDE approved universal voltage input power supply which will operate on any AC voltage from 100-250 volts. The extra cost of this power supply adds $100.00 to the list price for the 220VAC version.
