[Application of the method of liquid chromato-mass spectrometry for determination of bisoprolol and atorvastatin.]

A technique has been developed for the quantitative determination of bisoprolol and atorvastatin in mixed saliva on a LCMS-8040 triple quadrupole liquid chromatographic mass spectrometer with ionization, separation and detection of samples, which allows determining the concentration in mixed saliva of bisoprolol with an accuracy of 93.7 to 98, 5% and atorvastatin from 95.6 to 98.3%.
