These plastics keep me busy!
This time I have a peak with a very good signal in positive mode (better than UV). Sample: tefloncoated rubber stopper.
- UV max at 215 and 340 nm.
- Mass: 403.1 [M+H]
- Fragments at 357.1 and 359.1
I searched massbank.jp and googled a lot - no results so far. All ideas are welcome!
