一般說明
應用
- In the determination of partition coefficient of ethyl acetate in water at 0° C from independent analyses of the total amount of ethyl acetate present in the vial, by automatic equilibrium headspace gas chromatography and vapor phase calibration (VPC).
- It may be used in the analysis of volatile polar residual solvents present in pharmaceutical products, during development and optimisation of headspace SPME method by GC-MS.
- It may also be used in the isotopic analysis of 18O in the leaf water of C3 and C4 grasses, during establishing a grassland signature in veins, as it was found that grasses with different photosynthetic pathway have different interveinal differences.
- It may also find application, in investigating metabolism by Pseudomonas fluorescens of volatile haloaliphatic hydrocarbons like 1,2-dichloroethane and 1,2-dichloropropane, which are some of the major contaminants of underground aquifers.

Terpenes are present in essential oils derived from plants and often impart characteristic aromas to the plant or its oil. The SPME is a convenient, efficient, and easy to automate sample preparation technology for analyzing the terpene/terpenoid profile of these plant materials.
High-resolution profiling of terpenes and terpenoids to identify fragrance compounds and distinguish hops and cannabis varieties using SPME-GC/MS.
