Hi Rachel,
I work in an analytical lab that has multiple LC units. We do not have vented into a hood. Instead, the best practice is to use is a specialized waste can that has two fittings. The first will be hooked
to the LC, the second should have a coalescing/carbon filter to capture any vapors.
I’ve seen these in many analytical labs I have worked at or visited over the years, so pretty standard set-up in industry. Here is a link to the cans we use from Grainger, and the filter is in the compatible
products list. There are smaller options available, too, but we need the bigger size since we are running daily.
Hope this helps.
Phil

Subject: [DCHAS-L] LC with Acetonitrile Ventilation
Hello!
We are hoping to do some work with the LC this summer using acetonitrile but are concerned about ventilation of the fumes. Our waste currently runs to a bottle that has a closed funnel. Do labs typically have their
LC waste container in a fume hood for ventilation? Our LC is currently in a fairly small room that has one large vent in the ceiling. Any thoughts or recommendations would be greatly appreciated!
Thank you,
