介绍：重量法全自动水蒸汽动态吸附分析仪Aquadyne DVS 是美国康塔仪器公司为潮解、疏水性/亲水性、结晶化现象、微孔结构及样品形态的研究开发的系列重量法吸附分析仪，其出众的稳定性极大地提高了数据精度。
主要特点：
1）独立的天平核心区域控温环境确保仪器出色的长期稳定性
2）样品可通过干燥气体吹扫进行原位预处理
3）双天平设计功能更强大
4）应用于潮解、疏水性/亲水性、结晶化现象、微孔结构及样品形态的研究
Introduction: The Aquadyne DVS instruments are fully automated, gravimetric, one or two sample water vapor sorption analyzers. They measure adsorption and desorption isotherms of water vapor both accurately and sensitively, including sorption kinetics, with minimal operator involvement. The weight(s) of one or two sample(s) is / are constantly monitored and recorded as the relative humidity is automatically varied by the blending of dry carrier gas with a saturated gas stream using precision mass flow controllers.
The dual balance design of the Aquadyne DVS-2 and DVS-2HT allows increased analysis throughput, sideby-side comparison with known or reference materials, or an extended mass range for a single sample. The independently temperature controlled balance head environment ensures long term stability. The small sample chamber ensures rapid changes in sample atmosphere conditions when the relative humidity is altered during an analysis. Sample(s) can be pre-dried insitu up to 90° C (DVS-2HT) in a flow of dry gas. The processing software is available in a 21CFR Part-11 compliant version, and runs under Windows® XP, Vista and Windows 7.
