好的,USP
The hydrophobic filters typically used for gas filtration can be integrity tested using bubble-point(起泡点), diffusive-flow(扩散流,对于亲水的多一些), and pressure-hold tests(保压实验) that use a liquid of low surface tension to completely wet the pore structure of the filter membrane. Additionally, integrity testing can be performed by measuring the membrane’s resistance to wetting with water as a function of pressure. Water intrusion testing (水侵入法)is an example of this type of integrity testing. |
