method and device for performing a gravimetric titration with u0441u043fu0435u043au0442u0440u043eu0444u043eu0442u043eu043cu0435u0442u0440u0438u0447u043du0430 detection on the equivalent point of titration

摘要

the method and the device relates to the chemical analysis of substances which by titration.the method is that all operations in conducting titration: introduction of solid or liquid sample for analysis, dissolution of the solid sample or clearance u0435u0436u0434u0430u043du0435 of liquid sample introduction of reagents for spectro chemical photometric indication of equivalent point, adding u0442u0438u0442u0440u0430u043du0442u0430 and spectrophotometric u0438u0437u043cu0435u0440u0432 anne is carried out in u043au044eu0432u0435u0442u0430 placed in the spectrophotometer.excluding operations stirring of solution and photometric detection of spectro chemical equivalent point, all other operations control gravity meters do, by weighing electronic scale. titration is carried out with specially created for the target device.from one side fixed motionless u043au044eu0432u0435u0442u0430u0442u0430 the light beam to implement the spectrophotometric measurement, and on the other hand u043au044eu0432u0435u0442u0430u0442u0430 bound with the electronic balance for weighing. furthermore, with the mix solution in u043au044eu0432u0435u0442u0430u0442u0430.the device is reduced to one u0431u044au0440u043au0432u0430u043du0435u0442u043e received the vibrations that interfere with the proper performance of weighing with the electronic scale. the device protects the external light in u043au044eu0432u0435u0442u043du043eu0442u043e compartment of the spectrophotometer, which insures correctly carry out u0441u043fu0435u043au0442u0440u043eu0444u043eu0442u043eu043cu0435u0442u0440 u0438u0447u043du043eu0442u043e measurement.
