Dynamic vapour sorption (DVS) moisture analyser.

Surface Measurement Systems offers the latest dynamic gravimetric water sorption analyser--The DVS Intrinsic. The DVS Intrinsic rapidly measures moisture uptake and loss in a sample using a controlled flowing carrier gas at a specified relative humidity (RH) over a sample suspended from the weighing mechanism of our highly sensitive and stable digital microbalance (SMS UltraBalance). This detects the sorption of water vapour by the increase or decrease in sample mass. Applications include the impact of hygroscopicity, water sorption kinetics and water induced morphology changes (such as amorphous content) in pharmaceutical powders, tablets, APIs and excipients. Other applications include diffusion in packaging materials like blister packs and controlled release encapsulation. The analyser is capable of accommodating a sample mass of up to 4 g and with dimensions as large as 40 mm. The sorption behaviour of very small samples sizes (typically 1-20 mg) can be accurately determined. Changes in sample mass of 0.1 [micro]g and unrivalled long-term stability are hallmarks of the DVS Intrinsic.

The Intrinsic has a temperature range of 20-40 [degrees]C that is accurate to [+ or -] 0.1 [degrees]C, ensuring excellent instrument baseline stability as well as complete RH generation control. These features are critical for the accurate measurement of water sorption phenomena. Designed to meet the needs of small to mid-sized laboratories and manufacturing plants, the DVS Intrinsic combines ease of use with a low capital investment and maintenance burden. Add industry leading electronics, a software interface with step-by-step wizards and Isotherm analysis software, the DVS Intrinsic represents high performance with minimal operator training. The unit's small footprint makes optimal use of limited bench space. High-Throughput is achievable via a DVS-IntrinsiLink that expands the operation of up to five analysers from one PC.
