Our 310 Gas-less Educational GC system is ideal for undergraduate chemistry classes where the principles of gas chromatography are demonstrated on the same equipement students will encounter in industry. The Gas-less Educational GC includes a built-in "whisper quiet" air compressor and a CCD detector. The CCD detects combustible (hydrocarbon) molecules, and it operates on air carrier gas from the air compressor. Our educational systems are for domestic customers only, and only come in a 110V configuration.
