What is DVS Discovery? 

The DVS Discovery is a gravimetric sorption analyzer specifically built for the precise analysis of moisture and organic vapor sorption properties in solid materials. 

Across a wide range of industrial applications, solid materials undergo structural and performance changes through interactions with water vapor or organic vapors. The DVS Discovery is designed to evaluate the sorption and desorption behavior of solid materials in real time under diverse vapor environments, including moisture and organic solvents.

With precise control over temperature and relative humidity, the DVS Discovery enables measurements that replicate real-world conditions across a broad range of organic vapor and water vapor compositions. Its flexible configuration options — supporting diverse experimental conditions and accessories — allow for quantitative analysis of hygroscopicity, stability, and structural changes in a wide range of materials, including pharmaceuticals, polymers, food, and building materials.

Applications 

Pharmaceuticals — Hygroscopicity evaluation, amorphous content determination, and stability analysis of solids Polymers and Packaging — Phase transition analysis (Tg and RH) and evaluation of diffusion and permeability Food, Flavors, and Cosmetics — Water sorption isotherm and kinetic analysis Composites and Cellulosic Materials — Analysis of moisture and organic vapor sorption properties Sorbents and Catalysts — Sorption capacity and surface property evaluation Nanomaterials and Porous Materials — Research on molecular diffusion and sorption phenomena  

Key Features 

• Dual-Balance Design — Simultaneously measures two samples, improving experimental efficiency
• Wide-Range Temperature and Humidity Control — Temperature range of 10 °C to 70 °C and relative humidity range of 0% to 98%, enabling experiments under diverse conditions
• Precise Mass Measurement — The patented UltraBalance system detects minute sample mass changes in real time, enabling accurate analysis of sorption characteristics
• Competitive Sorption Analysis — Analyzes competitive sorption phenomena between moisture and organic solvents, enabling evaluation of sorbent selectivity and efficiency
• True0 RH Capability — Relative humidity control down to 0.0% RH, enabling measurement under fully dry conditions

01

Organic Vapor and Water Vapor Sorption Kinetics and Isotherms (10 °C – 70 °C) 

Obtain accurate and detailed data on sorption kinetics and isotherms of materials using either water or organic solvents. 

02

Dual-Balance Design for Simultaneous Mass Measurement 

The innovative dual-balance design enables simultaneous mass measurement of two samples, increasing throughput and reducing hands-on time. 

03

Expanded Functionality  

A wide range of modular accessories — including the patented Speed of Sound Sensor, microscope camera, sample in-situ pre-heater, and IR/Raman analysis sensors — extends the capabilities of the DVS Discovery. 

04

True0 Drying Capability at 0.0% RH 

As the only DVS instrument offering True0 RH, it can reduce water vapor partial pressure down to 0.0% RH. This makes it essential for analyzing hydrates and other compounds that only fully dehydrate below 1% RH, as well as for studying sorption and desorption behavior under low-humidity conditions.
