Tlhaloso: W107 ke electrode ea tšepe e mocheso o tlase e nang le sekoahelo sa sodium se nang le haeterojene e tlase.Sebelisa DCEP (electrode ea motlakase e tobileng) 'me u ka e tjheseletsa maemong 'ohle. Tšepe e kentsoeng e ntse e na le matla a ho thula hantle ho -100°C.
Tšebeliso: E sebelisoa bakeng sa ho tjheseletsa tšepe e mocheso o tlase joalo ka 3.5Ni.

Tsebiso:
- Electrode e lokela ho besoa hora e le 'ngoe mochesong oa 350℃ pele ho ts'ebetso ea ho tjheseletsa;
- Ho bohlokoa ho hloekisa mafome, sekala sa oli, metsi le litšila likarolong tsa ho tjheseletsa pele ho tjheseletsa;
- Leka ho sebelisa matla a manyane ha o tjheseletsa, ho tjheseletsa ka mekhahlelo e mengata le ka mekhahlelo e mengata.
