MilliporeSigma™ Supelco™ Headspace Vial with Screw Top

Description

Headspace vial with screw top

• Used 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
• Used in automatic equilibrium headspace gas chromatography and vapor phase calibration (VPC)
• Used in the analysis of volatile polar residual solvents present in pharmaceutical products, during development and optimisation of headspace SPME method by GC-MS
• 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
• 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.
