传说中的“进样口憋压测试”怎么做？我以下做的对么？

Procedure
1. Zero the manometer and install it in place of the column in the inlet.
2. Cap the inlet's septum purge fitting with a 1/8 inch Swagelok cap.
3. From the gc’s keyboard/controller, enter the length (30 m) and diameter (320 μm) for the capillary column being tested.
This places the system in pressure control mode rather than in flow control mode.
4. Pressurize the inlet to 25 psi.
This may take a few seconds.
5. Wait 10 minutes for the pressure to stabilize.
6. From the gc’s keyboard/controller, turn off the inlet pressure and record the initial pressure in the Results section.
7. Wait 5 minutes and then record the final pressure reading.

OQ/PV limit 5min<2psi

看来问题不大。

不过2psi，是14kPa，允许值有点大。。。

楼主是想看看进样口是否漏气吗？

是的，这就是实验目的。

psi相等于多少mpa?
