ABSTRACT
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%.

Retention of 17 organic compounds was studied in high-temperature liquid chromatography mode on Hypercarb porous graphitic carbon with subcritical water as an eluent. Three different eluent temperatures were studied: 150, 175 and 200⯰C. Abraham solvation parameters model was used for quantitative evaluation of retention data. It was found that increase of eluent temperature from 150 to 200⯰C results in decrease of cavity formation system parameter v from 2.9 to 1.7. No clear tendency can be observed for temperature dependency of other system parameters.
