Multi-Deans Switch Shimadzu Multi Dimensional GC/GCMS System | Superior features Deans Switching Standby (ist DET) Multi-Deans Switching Standby (ist DET) No Shift in Rtention Time This new technology significantly reduces the likelihood of fluctuations in the rtention times of eluted components. Multi-Heart Cutting - High Reproducibility Since the internai surface has been subjected to deactivation processing, a superior level of peak reproducibility is attained, and analysis with a high level of quantitative accuracy is possible. High-Precision Flow Control The pressure and flow rate of the carrier gas and switching gas are precisely controlled with an Advanced Flow Controller and an Advanced Pressure Contr驴liez This ensures superior reproducibility of analytical conditions.
