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.
USP Code: None
Phase:
  • Bonded
  • Proprietary
Temp. Limits:
  • ≤0.32 mm I.D., <2 μm: Subambient to 250 °C (isothermal or programmed)
  • ≤0.32 mm I.D., ≥2 μm: Subambient to 230 °C (isothermal or programmed)

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

Protocolos

In this article, SPME-GC was successfully used to identify many volatile compounds present in the headspace over several spirits.

There are three types of analyses: GRO, DRO, and TPH. The published methods are simply variations of these to meet the different analytical needs of the individual agencies.
