The development of a container-free sample environment which is particularly well suited for reaction studies of liquid samples by small-angle neutron scattering and related techniques is reported. Hydrogen exchange with the humidity from air is reduced by an encapsulating setup in a bag filled with an inert gas such as He. The effectiveness of this measure is quantitatively accessed by infrared absorption and gravimetry, and further correlated with neutron scattering.
报道了一种无容器样品环境的开发，该环境特别适合通过小角中子散射及相关技术对液体样品进行反应研究。通过将样品封装在充满惰性气体（如氦气）的袋子中，减少了与空气中湿度的氢交换。通过红外吸收和重量分析法对该措施的有效性进行了定量评估，并进一步与中子散射相关联。
