General description
Application
- 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).[1]
- 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.[2]
- 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.[3]
- 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.[4]

Protocols
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination in terms of sensitivity and selectivity.
