METHOD OF QUANTITATIVELY DETERMINING NOVOCAINE AMIDE Russian patent published in 1998 - IPC

Abstract RU 2106617 C1

FIELD: analytical methods. SUBSTANCE: method includes measuring optical density of sample at 280 nm wavelength using reference Novocaine solution. Specific absorption value of reference solution is measured at 290 nm wavelength and Novocaine amide concentration in sample is calculated using formula: x = A280•271,8•100/E1%1cm

•272,7 where A280 is optical density of the sample under investigation, E1%1cm
 specific absorption value of reference solution measured at 290 nm, 272.7 molar mass of Novocaine, and 271.8 molar mass of Novocaine amide. EFFECT: increased productivity and reliability of analysis due to using stable reference substance. 2 dwg, 2 tbl
