To install a .53mm capillary column in
theon-column injector youwill need two
1/8” swagelok nuts, two1/8” to .8mm
soft graphite reducing ferrules, theSRI
widebore columnadapter, a triangle file
to cut the columnanda7/32”wrench.
Youhave theoptionof usinga swagelok
1/16” to1/8” reducing fittingand1/16”
ferrule instead.
You canuseMXT typemetal ( stronglypre-
ferred ) capillary columnsas shown, or regu-
lar fused silica columns. The regular fused
silica columnsaremore likely tobreakespe-
cially in the injector due to the syringe frac-
turing the fragile fused silica
.
Remove the septum nut from the outside
of theoven. Now is agood time to in-
spect and change the septum if it is
worn.
Slidea1/8” stainless steel swageloknut
and 1/8” to .8mm soft graphite reducing
ferruleonto the column. Then slide the
column through the injector so it pokes
out the front of theoven.
