Ion mobility and negative-ion tandem mass spectrometry of phosphatidylglycerol (PG) and isomeric bis(monoacylglycerol)phosphate (BMP). (A) Ion mobility trace (total ion mobilogram) for [M−H]− m/z 773.5 of PG(18:1/18:1). (B) Product ion mass spectrum from CID of [M−H]− m/z 773.5 of PG(18:1/18:1). (C) Total ion mobilogram for [M−H]− m/z 773.5 of BMP(18:1/18:1). (D) Product ion mass spectrum from CID of [M−H]− m/z 773.5 of BMP(18:1/18:1). Collision energy at 30V.
