The determination of HETP and column efficiency for an annular preparative-scale gas-liquid chromatographic column
The purpose of this investigation was to design, build, and test a preparative-scale column which contained a blocked-off center tube, thus forming an annular space for the packing. The chromatographic system for this study consisted of 1-methylnaphthalene injections with helium carrier gas and a l...
