Isothermal GCs The GOW-MAC 69-550/750 gas chromatographs have been designed to meet the requirements of routine, day-to-deiy analytical investigation in industrial quality control laboratories, research labs, or in educational use. The 69-550 comes in four models; three 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. Both instruments are isothermally controlled, designed for high performance, sensitivity and stability.
Temperature Programmable GCs Using a Central Processing Unit these instruments permit temperature programming with excellent reproducibility. The microprocessor provides for selection and display of initial^ time and temperature, ramp and final time and temperature (400°C max). A simple keyboard and LED display make analysis easy for the chromatographer.
Digital Isothermal GCs The use of large scale integrated circuitry expands the capability of both the 69-550/750 ΙμΡ GCs and allows faster, simpler opera tion with digital reproducibility and stability. As before, the 69-550 \μΡ offers selection of two detectors. The 69-750 ΙμΡ uses dual FIDs and columns. All functions are controlled by thumbwheel switches and displayed on easy-to-read LEDs.
Fundamental GC The 69-150 includes many of the same features found in our more sophisticated GCs. It uses a TC cell and, like our other instruments, it is of outstanding value. In your lab, the 69-150 would be a valuable tool for student work and routine analysis.
The 69-550P has three TC detectors. The 69-750P has two FIDs. Both are dual column instruments with versatile sample injection systems. Optional accessories are available with a full capillary system for the 69-750P.
When it comes to our customer our dedication comes first. It's a sign of affection for your chromatographic needs!
