Isothermal GCs
Temperature Programmable GCs Using a Central Processing Unit these instruments permit
The GOW-MAC 69-550/750 gas chromatographs have been designed to meet the requirements of routine, day-to-day analytical investigation in industrial quality control laboratories, research labs, or in educational use. The 69-550 in four models; three comes with thermal conductivity detectors and one with gas density detector. The 69-750 uses a Flame Ionization Detector (FID), a single injection port and column. All instruments are isothermally controlled, designed for high performance, sensitivity and stability.
temperature programming with excellent reproducibility. The microprocessor provides for selection and display of initial time and temperature, ramp and final time and temperature (40Q°C max). A simple keyboard and LED display make analysis easy for the chromatographer. The 69-550P has three TC detector options. The 69-750P has two Both are dual column instruments with versatile sample injection systems. Optional accessories are available with system for the 69-750P,
