On April 25, 2015, Metrohm Tianjin Petrochemical Technology Training Conference was successfully held in Tianjin Petrochemical Training Center. This training session conducted special training on the chemical analysis technology of various oil products in the petrochemical industry, mainly explaining the application technology and new technical support of Metrohm's potentiometric titrator, cassette moisture meter and near-infrared spectrometer in the petrochemical industry. solution. At the meeting, a total of more than 30 technicians and senior engineers from the Sinopec system across the country participated in the training and discussion.

培训会现场

Metrohm titrators, Karl Fischer moisture meters and near-infrared spectrometers have a wide range of applications in the petrochemical field. For example, the temperature titration method is used to determine the acid value of petroleum. This training also focused on the application of Metrohm's near-infrared spectrometer in the determination of crude oil, blended oil, and on-site oil. Compared with traditional detection and analysis methods, near-infrared spectroscopy can quickly (30-60 seconds), non-destructive, environmentally friendly, accurate, and simultaneous multi-component measurement, which greatly improves the efficiency and accuracy of the experiment.

859 Titrotherm temperature titrator

Main functions and features

        859 Titrotherm is a potentiometric titration with a temperature probe. The temperature probe is based on semiconductor technology (thermistor) and incorporates Metrohm’s innovative electrode technology. The response time is only 0.3s and the resolution is as high as 10-5 K. It is an ideal electrode for temperature titration and can accurately and quickly respond to any temperature. Variety.

        Metrohm's Dosino bottle-top drive dosing technology has established a new volumetric titration standard, which not only saves space, but also ensures high accuracy. Clear software interface, you can adjust the screen, display special method parameters, in order to quickly find important commands or parameters. The end point is determined by calculating the first and second derivatives of the titration curve, and additional parameters can be optimized to improve reproducibility.

        Its salient features:

        ● Both endothermic and exothermic reactions

        ● Use the thermistor to measure the temperature change, and indicate the end point by the temperature change rate

        ● The electrode does not need calibration and maintenance

        ● One electrode is suitable for multiple titration types

        ● There is no electrical contact between the electrode and the solution

        ● Reduce sample preparation process

        ● Fast determination-usually only takes 2-5 minutes

        ● Unskilled users can operate

        Application field

        Applicable to: acid-base titration (including weak acid and weak base); redox titration; complexometric titration (such as EDTA); precipitation titration; non-aqueous titration.

        Applicable industries such as:

        Chemical manufacturing; fertilizer; mineral smelting; electroplating industry; production of synthetic acid blends and munitions in the semiconductor industry; pigments and bleaching agents (modifiers); TAN and FFA....
