A method for determining the earthy and musty odors 2-methylisoborneol (2-MIB) and geosmin in drinking water using static headspace-GC-MS is described. To achieve lower detection limits, split ratio was optimized with ramped inlet pressure for large headspace sampling volume. The ramped inlet pressu

## Abstract The formation of ethyl derivative from anions and the conjugate bases of weak acids through the reaction with ethyl p‐toluenesulfonate in strongly basic aqueous systems was used as a precursor to analysis by static headspace sampling with capillary gas chromatography‐mass spectrometry.
## Abstract Static headspace (HS) sampling has been commonly used to test for volatile organic chemicals, usually referred to as residual solvents (RS) in pharmaceuticals. If the sample is not soluble in water, organic solvents are used. However, these seriously reduce the sensitivity in the determ
