A capillary GC-MS method has been developed for analysis of guazatine. On a short capillary column (DB-5, 0.25 mm x 5 m, df=0.1 micrometer), a symmetrical peak of trifluoroacetate of bis(trifluoromethyl)pyrimidine derived from guazatine was recorded. Its EI mass spectrum showed the base peak at m/z 244 and the molecular ion peak at m/z 795. By the SIM method with these two ions, calibration curves were fairly linear in the range of 40-750 pg. The minimum detectable quantity was determined to be 40 pg
