Hi #TeamMassSpec !
I'm looking for a new stereo microscope for the MassSpec Lab (for troubleshooting tiny parts and so on) Any suggestions? Mid-budget, no digital camera options would be best.
Thanks for recommendations and sharing experiences!

When analysing peptides from in-gel digests by LC-MS/MS, has anyone noticed a 1+ ion of m/z 1342.93 after washing the column with 80% ACN? We are leaving the pump at 80% ACN at 1uL/min for 5 mins after our usual 0-40% ACN gradient. Doesn't correspond to any contaminants. #massspechelp
Hello Waters Synapt users! Does anyone know of documents that explain how changing the values on the TriWave, TriWave DC, IMS-Config and Trapping tabs affect the mobility separation? I'm trying to better optimise for multiply charged peptides and don't want to have to figure out 1x1. #massspechelp
Can someone running XCalibur 4.5 with a Waters M-class and 96 well plates please get in contact with me? We are trying to switch to 96 well plates from 48 vial racks and are having problems. I need some guidance! #massspechelp
Good afternoon MassSpecSky! I wondered if anyone is seeing issues with their acetonitrile in LCMS? The free cyanide-derived gold complex at 248.973 m/z (- mode) has really become problematic for us and it is affecting multiple MS-grade solvent vendors.
