Can your G.C. isolate a n important group of peaks a n d transfer t h e m t o a second column for better analysis? The Siemens SiCHROMAT 2 Can
Valvelessly. With the patented, valveless "live" column switching system important trace components can be "heart-cut" from a multi-component sample and transferred to a second column for further analysis. By reducing the ratio between the trace and main components and utilizing a second column of different polarity, substantially increased resolution and optimized separations can be achieved. Valveless "live" column switching is an exclusive feature of the Siemens SiCHROMAT 2 Double Oven Gas Chromatograph. Valveless means the sample does not come in contact with any switching valves. It is a pulseless, low dead volume system with extremely short ( < 1 second) switching times. The "live" principle allows switching times for transfer to be determined directly and the effect is immediately seen.
