4 Installing the column
4.1Capillary Column Overview
Two types of columns can be installed in a gas chromatograph.
The first type, the capillary column, chemically fuses the liquid phase to the interior of the column
wall.
The other type, the packed column, fills the interior of the column with packing material, with the liq-
uid phase coating the particles. This type of column is becoming obsolete.
Fused silica, chemically bonded, capillary columns are in wide use today, this chapter describes
capillary column installation in a split/splitless injection system. Analytical conditions, as well as the
analytes, determine the column selection.
Column vary in length, polarity, film thickness, and inner diameter.
The GC-2010 Plus is designed to be used only with capillary columns. For using packed columns,
contact your Shimadzu representative.
