1Identification of l-carnitine and its impurities in food supplement formulations by online column-switching liquid chromatography coupled with linear ion trap mass spectrometry.

Wang H1, Xie S1.

J Sep Sci. 2016 Nov 15. doi: 10.1002/jssc.201600652. [Epub ahead of print]

The identification of impurities in l-carnitine by mass spectrometry is difficult because derivative reagents or ion pair reagents are usually used to separate and increase the retention of l-carnitine on the reversed-phase column. In this study, four impurities including 3-chloro-2-hydroxy-N,N,N-trimethylpropan-1-aminium, 3-cyano-2-hydroxy-N,N,N-trimethylpropan-1-aminium, 3-carboxy-N,N,N-trimethylprop-2-en-1-aminium, and 4-chloro-2,3,4-trihydroxy-N,N,N-trimethylbutan-1-aminium were identified in l-carnitine and its tablets by using two-dimensional column-switching high-performance liquid chromatography coupled with linear ion trap mass spectrometry.
