We been having difficulty cleaning the LC-MS/MS metal cone.
We use standard 45:45:10 methanol/water/formic acid 30 min ultrasound protocol, and some pure formic acid in more difficult ones, but sometimes its just not enough.
We work with liver and urine samples.
Any recommendations for a more efficient cleaning?
Thank you all for your time!
May the science be with you!
