MilliporeSigma™ Supelco™ Headspace Vial with Screw Top

Description

• 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
