General description
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.
Application: This intermediate polarity column, designed for analyses of volatile organic compounds (VOCs), offers great retention and resolution of highly volatile compounds. Use this column in direct injection ports or coupled to purge and trap systems.

Application
VOCOL® column (diphenyl dimethyl polysiloxane with crosslinking moieties) may be used for their relevancy to the purge-and-trap technique and GC/MS analysis of 34 volatile organics. It was also found suitable in being used for determination of volatile compounds by whole column cryotrapping.

Voice is a dominant component of everyday speech in all languages. The possibility is examined that its use may have evolved so that its timing in connected speech is ideal from the point of view of information theory-with voicing taking

In this study we investigated how important significant others find it to be informed, supported, and trained by speech-language pathologists (SLPs) and to what extent they perceive their expectations and needs as to these aspects to be fulfilled. Furthermore SLPs

Vocal emotions are expressed either by speech or singing. The difference is that in singing the pitch is predetermined while in speech it may vary freely. It was of interest to study whether there were voice quality differences between freely
