Our DVS Systems: High Throughput Dynamic Vapor Sorption
Our DVS systems are revolutionizing material analysis through their versatility and high sample throughput. They enable continuous measurement of water uptake and release by your samples as a function of relative humidity and temperature. Gain detailed insights into the sorption isotherms and sorption kinetics of your materials. Understanding moisture-induced behavior is essential for the handling, processing, storage, and stability of a product. The multi-sample capability streamlines typically time-consuming experimental series and allows for direct comparison between different samples.
-
SPS Series
The fully automated SPS multi-sample systems offer the highest resolved sorption measurements on the market over a wide temperature range. The systems are highly versatile, enabling the simultaneous measurement of up to 23 samples supporting the use of additional sensors (e.g. Raman).
-
Vsorp Series
The Multisample Vsorp instruments are the result of our many years of experience in instrument engineering. They are designed for DVS measurements at a limited temperature range offering an excellent price to performance ratio at unrivaled versatility and accuracy.
Precise Humidity Generators for Controlled Environmental Conditions
Alongside temperature, the relative humidity of the environment plays a crucial role in the properties of materials and products (structure, stability, flowability). Our high-precision humidity generators enable you to create defined environmental conditions for reliable analyses and measurements.
-
MHG32
The MHG32 is a modular humidity generator specifically developed for applications in demanding instrument environments with small volumes, where rapid changes in relative humidity are required. By generating and controlling humidity directly at the target system, it enables fast and precise control behavior.
-
MHG100
The MHG100 is a modular humidity generator designed for precise control of relative humidity in larger measurement chambers and open systems with higher gas flow rates up to 15l/min.
Humidity Conditioning of Powders with the Powder Conditioner
The properties of powders, such as flowability and compressibility, are significantly influenced by their moisture content. The proUmid Powder Conditioner enables targeted humidity conditioning of powders, granules, or pellets at controlled relative humidity. Through the Dynamic Flow Method, a defined gas flow is directed through the powder bed, with temperature and humidity continuously monitored. This ensures a homogeneous moisture distribution which is essential for reliable analyses and process controls.
-
Powder Conditioner
The proUmid Powder Conditioner enables precise humidity conditioning of powders, granules, and chunky samples. Through controlled relative humidity, material properties are optimized to improve processing steps such as tableting or dosing.
Comprehensive Accessories for Your proUmid Systems
Expand the capabilities of your proUmid sorption testing systems with our comprehensive accessories. The large measuring chamber of SPS and Vsorp systems enables the use of modular sample holders and additional sensors – our hardware and software options offer you maximum flexibility. Precisely adapt your instruments to various measurement tasks e.g. permeability measurements and real size packages.
-
Video Camera
The video camera option for SPS sorption systems enables visual monitoring of moisture-induced changes such as color alterations, crystallization, or crack formation by capturing pictures at certain points during the measurement.
-
Raman Spectroscopy
Combine your water vapor sorption measurements with Raman spectroscopy enabling simultaneous analysis of sorption behavior and molecular structural changes, such as hydrate formation or crystallization of amorphous materials.
-
Membrane Dryer
The efficient membrane dryer ensures optimal analysis conditions. As a link between sorption instruments and the compressed air network, it supplies filtered, dried air for up to two devices – perfectly tailored to the requirements of SPS and Vsorp systems.
-
Permeability Kit
proUmid's Permeability Kits enable the precise gravimetric determination of water vapor permeability for many materials such as coatings, paper, plastic films and other packaging materials.
-
Large Objects Kit
The innovative sample holder expands your analysis capabilities to 5 large-format objects like cigarette packs or tablet blisters.
-
Sample Trays
The proUmid DVS instruments are compatible with various exchangeable sample trays, using different sample dishes in number and size.
-
Sample Dishes
Our sample dishes come in different size and inserts for specific sample preparation.
-
MCC Reference
The MCC Humidity Reference developed by proUmid enables a fast and reliable validation of gravimetric DVS instruments.
Powerful Software Solutions for the Evaluation of Sorption Data
proUmid offers advanced software packages for the analysis of moisture sorption data generated with the SPS and Vsorp series systems. The programs enable comprehensive visualization, evaluation, and documentation of the measurement data. Functions include tabular and graphical representations, freely configurable diagrams for sorption kinetics and isotherms, and an extended display for multi-sample measurements. Built-in curve fitting (BET, GAB), water vapor permeability calculations, and a flexibly customizable report generator facilitate in-depth, precise analysis. This allows even complex sorption processes to be efficiently interpreted and documented.
-
DVS Analysis Software
proUmid's DVS analysis software allows for the import and advanced evaluation of measurement data from water vapor sorption analyses. Specifically developed for the convenient handling of multi-sample measurements, it is compatible with SPS and Vsorp systems.
-
21 CFR Part 11 Compliant Software Package
In a GLP or GMP certified environment, the SPS/Vsorp standard software does not meet the requirements for trustworthy and reliable electronic records. Therefore, the 21 CFR Part 11 compliant software package is available.
