The Novel Fast GC Concept
The Fast GC Mounted on an Agilent 5975 GC-MS
Our low thermal mass (LTM) ultra-fast gas chromatograph (US Patent 8,591,630) is a new technology and device. The fast GC utilizes a short standard fused silica capillary column that is inserted into a resistively heated stainless steel tube that serves as its heating oven. The Fast GC is located and mounted outside the standard GC oven on its available top detector port, while the capillary column is connected as usual to the standard GC injector and detector. This new type of fast GC enables less than one minute full range temperature programming and cooling down analysis cycle time.
The use of resistively heated tubing enables the use of any available fused silica column without restriction on the internal diameter, (from 0.1 mm to 0.53 mm), separation film type and thickness as well as their supplier vendor. Four active column lengths can be used (1.8, 3.6, 5.4 and 7.2 m) and column trimming or replacement is easy. Since the column is cut from a standard available fused silica column its price is far lower than that of any other fast GC column so you can comfortably experimentally optimize the fast GC for its operation with the most suitable column for your needs. The Fast GC can be used with any GC injector or detector including FID, TCD, NPD, ECD, FPD, PFPD and MS.

Major Advantages
- Broadest range of columns – Can use any standard fused silica column from any vendor
- Lowest cost of columns
- Fastest GC around – Can generate sub one minute full analysis cycle time (from injection to next injection)
- Unique top GC mounting – The GC can also be used with another injector/column/detector
- Easy and fast column replacement
