Fast Gas Chromatography Solutions

A recent publication has studied the performance of different columns featuring different lengths and internal diameters at different heating rates and with different carrier gas types and flow rates (Facchetti et al., 2002). 

Note Four pairs of peaks remain unresolved using the EPA 610 packed column technique, marked with.  

The chromatograms were run in either constant flow or constant pressure mode as indicated using a TRACE Ultra GC with a TriPlus autosampler (Thermo Fisher Scientific, Milan, Italy) with a FID detector. 

TR-5MS ID 0.25 mm, Film 0.25 pm Initial Temp 100 °C Rate 1 5°C/min to 300 °C Carrier Gas Helium Gas Flow 1.5 mL/min (constant flow) Detector FID Split Ratio 50 1 Injection vol. 1.0 pL by TriPlus autosampler. Sample run rate is 1 per h (includes oven cooling). 

Temperature ramp rate Higher starting temperature and steeper heating rate - peaks elute faster
