PureCol 色谱柱进样口衬管

When nonvolatiles accumulate in the column inlet, you must replace several inches of packing or the entire column. A

silanized glass PureCol liner, inserted in the column inlet, solves this problem simply and inexpensively. When column

performance begins to deteriorate, you can quickly and conveniently replace the insert often without removing the

column from the instrument. Replacement time is comparable to replacing a septum. Replace the PureCol liner when you

change the septum, or when you analyze a new type of sample.

PureCol liners are available in two sizes. The smaller size fits 2mm ID glass columns with chamfered ends and 175px of straight,

unpacked inlet. The larger size fits any 4mm ID glass column that has 175px of straight, unpacked inlet. Use PureCol liners

with a 2" (125px) 21-gauge or finer needle.
