Efficient Multiparameter Measurements on Lubricants and Oils

Would you like to measure highly viscous lubricant and oil samples at up to 80°C? Anton Paar has the solution: Modulyzer for Petro.

Density and the refractive index play a key role in the production of fuels, waxes, lubricants and similar materials. Many of these products are specified based on these two parameters in ASTM as well as other standards.

Products in the petrochemical industry are often highly viscous and therefore not always easy to measure. To cope with these challenges, Anton Paar has developed Modulyzer for Petro. In its basic configuration, Modulyzer for Petro is a combination of a DMA 4100/4500 M density meter or a DMA 5000 M (the most accurate density meter in the world), an Abbemat-HP/WR refractometer and an Xsample Heated for the efficient, flexible and modular measurement of highly viscous petrochemical samples at temperatures of up to 80°C. Measurements with Modulyzer are highly reproducible, precise and easy to perform.

The magazine, the needle and all hoses are electrically preheated to a set temperature. As the viscosity of the samples drastically decreases when they are heated, the measuring cells of DMA M and Abbemat-HP/WR can be swiftly and effortlessly filled.

After the measurement, Xsample Heated recovers the sample and automatically cleans the system. Sample handling is made easy and convenient for the user. The automatic filling warning generated by FillingCheck^TM on the DMA Generation M density meters, the check of the filling procedure via U-View^TM and the temperature management with ThermoBalance^TM result in stable and reliable measuring results. LIMS connection is also possible, turning Modulyzer for Petro into a versatile partner in the laboratory.

Modulyzer for Petro offers a wide range of features such as the API compensation of the density measurement. In the case of measurements at high sample temperatures, after which results should also be shown for a reference temperature such as 20°C, this can save time and costs. These time savings are especially important regarding intermediate products, which have to be measured with great accuracy. If the measurement results do not accord with specified values, corrective actions can be taken immediately.

One measuring system – many functionalities

In addition to its modular concept, Anton Paar’s Modulyzer for Petro offers numerous advantages such as simultaneous measurement of density and the refractive index, unsurpassed accuracy and reliability and automated filling by Xsample Heated. Modulyzer for Petro is designed for space-saving Plug & Play installation, requires small sample volumes only and protects operators from exposure to putrid or hazardous solvents.
