Sequences of liquid crystal polymers (LCPs) was analyzed by ion mobility (IM) quadrupole (Q)-time-of-flight (ToF) mass spectrometry (MS). For the ionization of LCPs, lithium salts was used as the cationizing agent. For trimers of bipolymers (X and Y), there are isomers of αXYYω, αYYXω, αYXYω of the same m/z values, where the acetyl and carboxy end groups are denoted as α and ω, respectively. These isomers were separated into two peaks by IM even though the XX and YY resulted in a single peak in each driftgram. The sequences of the trimer isomers were identified by IMS-MS/MS and it was found that the cross section of αYYXω is lager that those of αYXYω and αXYYω.
