一般描述

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
应用：这种被设计用于挥发性有机化合物（VOC）分析的中间极性色谱柱可为高挥发性化合物提供较高的保留时间和分辨率。可直接通过进样端口或偶联至吹扫捕集系统而使用该色谱柱。

VoiceRelease is a progressively structured treatment system that aims to release the voice through muscle tension reduction by manual therapy, thereby facilitating healthy voice production. The VoiceRelease treatment should closely interact with functional voice training and should therefore be carried
