waxes plugging up system
Posted: Wed Jul 20, 2005 2:45 pm
Anybody know how to filter waxes out relatively easy from an on-line sample stream?I cannot increase my temperature of the sample line anymore to keep the wax in solution. Sample temp is ~ 95C. The wax plugs up my switching valve in the over( 110C). I have a 5um swirl clean and then a 2 um in-line filter in series before the GC injection. The problem occurs as the sample cools after the filters and knocks out more wax.
