ガスサンプルを収納するバイアル内部のガス減圧率を制御する方法、装置、およびシステム |
摘要 |
The present invention relates to methods and systems for controlling depressurization of a vial containing a gas sample. The disclosed systems and methods are employed during sampling and/or analysis of the gas sample. One exemplary method for controlling depressurization of a vial containing a gas sample includes establishing fluid communication between a sample loop of a head space sampling device and the head space of the vial. A sample gas pressure is established within the head space of the vial. The sample loop is connected in fluid communication with a lower pressure environment through a ventilation pathway. A ventilation valve within the ventilation pathway is used to vent gas from the vial through the sample loop to the lower pressure environment at a predetermined rate. Devices and systems for depressurizing a vial containing a gas sample at a predetermined rate are also disclosed. |
