        ABSTRACT    OBJECTIVE: To establish GC-MS method for the content determination of three toxic impurities in
        glycerophosphorylcholine raw materials,such as epichlorohydrin,glycidyl,3-chloro-1,2-propanediol. METHODS:Four batches of
        glycerophosphorylcholine raw materials were used as test samples. The determination was performed on ZB-WAXplus TM  column,
        and the injector temperature was 200 ℃;the sample injection adopted splitless injection mode,using helium(He)as carrier gas,
        in constant current mode;the temperature program for the column was initially heating at 30 ℃ for 1 min,rising to 220 ℃ at a
        speed of 30 ℃/min then remaining 5 min. The ion source was electrospray ion source (EI),the ion source temperature was
        200 ℃,and the ionization energy was 70 eV;transmission interface temperature was 250 ℃,and mass spectrum monitoring mode
        was selected ion(SIM). Detection ions were epichlorhydrin [mass charge ratio(m/z)49,57,62],glycidyl(m/z 31,43,44),
        3-chloro-1,2-propanediol(m/z 44,61,79). The solvent delay time was 3 min. RESULTS:The linear range of epichlorhydrin,
        glycidyl and 3-chloro-1,2-propanediol were 29.86-746.48,172.91-922.18,21.18-211.85 ng/mL,respectively(all r>0.999 0). The
        detection limits were 19.91,115.27,10.59 ng/mL,respectively. The limits of quantitation were 29.86,172.91,21.18 ng/mL,
        respectively. RSDs of precision (n=6),reproducibility (n=6) and stability (placed at room temperature for 12 h,n=8)
        tests were all lower than 10%. The average recoveries were 93.88%,91.45%,91.86%,and RSDs were 5.10%,3.10%,2.49%
       (n=9),respectively. In the 4 batches of glycerophosphorylcholine raw materials,three toxic impurities were all not detected.
        CONCLUSIONS:Established GC-MS method is simple,efficient,accurate and repeatable,and it can be used to determine the
        contents of three toxic impurities in glycerophosphorylcholine raw materials,such as epichlorohydrin,glycidyl,3-chloro-1,
        2-propanediol.
