一般描述

When nonvolatiles accumulate in the column inlet, you must replace several inches of packing - or the entire column. A silanized glass PureCol sleeve, inserted in the column inlet, solves this problem simply and inexpensively. When column performance begins to deteriorate, you can quickly and conveniently replace the sleeve - often without removing the column from the instrument. Replacement time is comparable to replacing a septum. Replace the PureCol sleeve when you change the septum, or when you analyze a new type of sample. PureCol sleeves are available in two sizes. Use PureCol sleeves with a 2 in. (5 cm) 21-gauge or finer needle.

其他說明

Fits any 2 mm I.D. glass column with 7 cm of straight, unpacked inlet (end must be chamfered).
