## Abstract Size exclusion chromatography (SEC) has been demonstrated to be an effective and reproducible sample pretreatment procedure for removal of heavy oil matrices prior to GCβAED analysis of metalloporphyrins, and for the resolution of volatile metal species into clean and defined fractions.
## Abstract A headspace solvent microextraction method was developed for the trace determination of geosmin, an odorant compound, in water samples. After performing the extraction by a microdrop of an organic solvent, the microdrop was introduced directly into a GCβMS injection port. Oneβatβtheβtim
