The capillary analysis system of
INE-112N-GC
series can use a variety of capillary columns, such as a glass capillary
column and a flexible quartz capillary column (fused silica capillary column). The external diameter of optional glass
capillary column is 0.9mm ~ 1mm; the outer diameter of flexible quartz capillary column is 0.375mm ~ 0.45mm. For
different capillary column, different capillary seal gasket should be used. See the table below.

Note: for general capillary column with inner diameter 0.05mm~0.25mm, the outer diameter is 03.75mm; for the inner
diameter 0.32mm, the outer is 0.45mm; for the inner 0.53mm, the outer is 0.69mm.
If you choose a larger diameter capillary column (such as: inner diameter 0.53mm, 0.75mm, etc.), you can ream the
sealing gasket with a drill bit (the diameter of the drill bit is similar to the outer diameter of the capillary).
