Removing m/z 288 from LCMS
Posted: Wed Jul 20, 2005 1:30 pm
LC-MS-ESI, flow rate 0.3ml/min, probe temp 450 degrees celsius, cone voltage 50V, mobile phase 95% acetonitrile, blank 95% acetonitrile. There is a peak always when the blank is run, Retention time is 1.37 min and m/z is 288.1. This peak is also observed when a sample of Hexamethylene diisocyanate is run. What is the cause of this and how can I get rid of it in order to get a smooth baseline? Please help
