'No.' A gentle wind drifted in through the arches supported by coupled columns
, while the children and the sun abandoned the open quarters.
Because the 3.6 micron core-shell particles produce lower backpressures than traditional media, longer or coupled columns
can be used to increase resolving power on both HPLC and UHPLC instruments.
GCxGC separates the sample using two coupled columns
and a modulator interface that quantitatively transfers and compresses the sample to the second column, resulting in improved separation, sensitivity and reproducibility.
