Water Selective Moisture Analyzer: Brabender Aquatrac-V

Overview

The Brabender Aquatrac-V moisture analyzer determines water-selective residual moisture in plastics in compliance with DIN EN ISO 15512:2019 and is described as the only instrument on the market with that compliance claim. The instrument uses the chemical reaction with calcium hydride: the sample is heated under vacuum, the released water reacts with calcium hydride and produces hydrogen, the resulting pressure increase is tracked and the water content is calculated based on the reaction equation. Key performance and operating specifications: - Resolution: 0.01 mg / 1 ppm / 0.0001 % H2O - Measuring range: 0.0001 % to 60 % H2O (relative) and 0.01 % to 60 mg H2O (absolute) - Precision: Better than ± 1.4 % of measuring range end value - Sample weight: From 0.1 g to max. 130 cm3 - Measuring temperatures: 60 °C to 200 °C in 1 °C steps - Measuring time: Approx. 10 min. to 60 min. depending on material - Display units: %, ppm, mg The Aquatrac-V is presented as a direct measurement method that does not require calibration or recalibration like NIR, and it includes software, an extensible methods database for various polymer types, and connectivity for data access from devices and third-party systems. Use the Aquatrac-V for laboratory quality control and for process control to obtain water-selective moisture measurements of plastics in line with DIN EN ISO 15512:2019. It can prepare dried polymer samples for Melt Flow Rate (MFR) determination in one step, avoiding the need for specialized labs or hazardous chemicals. The instrument is explicitly associated with the Chemical Industry and applications for Polymers, Elastomers, and supports simple, safe operation that does not require special staff while enabling data sharing and connectivity with third-party systems such as LIMS and ERP.
