9.1 Chemical trap replacement procedure:化学捕集的更换程序
• ***：Set the analyzer in manual injection mode and wait the end of cycle.
等一个周期结束后，在手动进样模式下设定分析仪。
• ***：Record the carrier pressure and flow.
记录载气压力和流量
• ***：Remove the expired trap.*
移开需要更换的阱
• ***：Remove the caps (or plugs) from the new trap.
移开新阱的封帽或者堵上换下的阱的封帽
• ***：Quickly install one end of the trap to the «trap in» labeled bulkhead. Wait two to three minutes and connect the other end of the trap to the trap out bulkhead.
快速安装，将的阱的一端连至阱进上，等待2…3分钟，连接另一端到阱出上。
NOTE: When you remove the expired trap from the gas circuit, the plasma will shut off. It will restart when the carrier flow will come back higher than 10 sccm.
注意：当你从气路上拆下要换的阱时，等离子体将关闭。当载气流量恢复超过10 sccm时，它将重新启动。
• Let the system stabilize and readjust the carrier flow. If the carrier pressure is different from the previous one for the same carrier flow, you will have to enter new timing parameter for the beginning and ending of a peak. Furthermore, venting ending time may require slight readjustment. This is caused by different pressure drop from one trap to the other.
待系统稳定后，重新调整载气流量。如果载气压力与以前的压力不同但流量相同，你只有输入一个新的定时参数以确定一个峰的开始和结束时间。此外，吹扫末期时间将需要做细小调整。这些都是由于从一个阱换成另一个阱产生不同的压力而造成的。
NOTE: After trap replacement, there will be some amount of nitrogen inside the trap. If your application is low ppm measurement of N2 in O2 you may have to wait 24 hours to get a stable reading. If you are measuring high level of nitrogen (> 80 ppm), one hour of purging will be enough.
注意：阱更换以后，在阱里面会残留一定数量的氮。如果你需要测量低PPM量程的氧中氮，你将不得不等待24小时，才能得到一个稳定的读数。如果你测的是高含量的氮（> 80 ppm），一个小时的吹扫就足够啦！
