MaConDa -- A nice resource for identifying contaminants
This is a cool resource I recently stumbled across! The MaConDa is a really easy and simple site that has exact mass information on previously identified contaminants in MS/MS runs. I know most of us have the supplemental information Excel sheet somewhere from that cool paper from a few years ago lying around somewhere, but this is like that with a couple of neat twists.
1) You can filter by instrument type (ion trap, QQQ, or TOF [probably what you'd use for Orbi])
2) You can set a custom PPM error, such as that for your instrument
3) You can filter by contaminant type
4) You can output a list that contains adducts. Icing on the cake!
Check MaConDa out at this link. I bet you'll end up using it sometime. I used it today!
