一般描述
这些样品瓶需要带 18mm 螺纹的专用瓶盖。标准 18-400 螺纹瓶盖不适合该样品瓶。这些样品瓶可用的瓶盖货号为 SU860101（PTFE/硅树脂，1.3mm 厚）、SU860102（PTFE/丁基橡胶，1.6mm 厚）和 SU860103（PTFE/硅树脂，1.5mm 厚）。这些瓶盖使用不锈钢材料并具有磁性。
应用
Headspace vial may be used for the following:
- 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.
