Repacking a split insert
Since, for a split insert, its packing material is discarded in cleaning, the
insert must be repacked.
Note: Repacking with small•diameterglass beads is not recommended:
they are usually contaminated with metal filings due to sieving
procedures used. If they must be used, thorough cleaning (chemical and
physical) is required.
Use a fresh, small amount of a conventional coated packing such as
2% OV•1on 100/120 mesh, Chromosorb W•HP.
Packing is held in place between plugs of silanized glass wool (Part
No. 8500•1572).

should be at least 35 mm between the top of the insert and the top of
the packed section.
