1. Xhuma ugesi bese uxhuma i-outlet yejeneretha ye-nitrogen endaweni yokungena enkulu ye-spectrometer usebenzisa ishubhu. Vula iswishi kusibonisi sejeneretha ye-nitrogen (qiniseka ukuthi uvula ivalvu ngemuva kwejeneretha ye-nitrogen);
2. Qaphela ngokucophelela ingcindezi yokukhipha i-nitrogen generator kanye nokuhlanzeka kwe-nitrogen. Ukucindezela kwe-outlet ngokuvamile kuzungeze ibha engu-7, futhi ubumsulwa be-nitrogen kufanele bube ngaphezu kwama-99%;
3. Ngemuva kokusetshenziswa kwe-mass spectrometry, linda kuze kube yilapho i-Desolvation Temp yehla ngaphansi kwama-degree angu-60 ngaphambi kokuvala i-API GAS;
4. Vala ijeneretha ye-nitrogen.
