Multi-Deans’ Switching
In the past, multidimensional GC has been accomplished using a switching
mechanism known as Deans’ Switch. However, this system results in such
problems as a reduced recovery (sample loss) and fluctuations in retention time
after column switching. The MDGC/GCMS-2010 system incorporates multiDeans
switching, a new mechanism that significantly reduces the likelihood of
fluctuations in the retention times of components eluted after column
switching, even when column switching is performed several times.
