- WP-097Why switch to OMNIS Client/Server (C/S)?
OMNIS Client/Server boosts business performance with scalable server management, cutting costs by reducing hardware, energy use, and maintenance across locations.
- AN-T-240Total acid number with conductometric titration
The total acid number (TAN) is an important parameter for assessing the acidity of oils and fuels. This Application Note determines TAN using conductometric titration.
- WP-085Improved antioxidant monitoring of in-service industrial lubricants
Voltammetry (VA) is a fast and established method for testing the remaining antioxidant content in industrial lubricants. The flexible and modular Metrohm VA system setup discussed in this White Paper delivers more repeatable and more reproducible results which fulfill all ASTM requirements. Additionally, users can automate the complete analysis process which makes it possible to run series of samples completely unattended.
- AN-T-182Determination of the bromine number in petroleum products and aliphatic olefins according to ASTM D1159
The bromine number is an important parameter for the determination of aliphatic C=C double bonds in petroleum products. The bromine number is usually determined using electrochemical titration at 5 °C, where the bromine is generated in situ from a bromide/bromate solution. For the titration, a solvent mixture of glacial acetic acid, methanol, and chloroform is used. In this Application Note, the toxic chloroform was replaced with diethyl carbonate.
