CS6512W-SE Potassium Ion Electrode

Takaitaccen Bayani:

Bayani dalla-dalla:
Nau'i: PVC membrane ion-selective electrode. Matsakaicin aunawa: 0.04–39000 mg/L. Matsakaicin zafin jiki: 0–50 °C. Juriyar matsin lamba: Ba ya jure matsin lamba. Firikwensin zafin jiki: Babu. Yanayin lantarki: Electrode guda ɗaya (wanda aka yi amfani da shi tare da na'urar lantarki mai daidaitawa) Kayan gida: PVC. Zaren haɗi: PG13.5. Tsawon kebul: 5 m ko kamar yadda aka amince. Ƙarewar kebul: An yi gwangwani ko kamar yadda aka amince.
Tushen sinadarin potassium ISE na zamani yawanci shine membrane mai ruwa-ruwa wanda aka yi da polymer ko membrane mai tushen PVC na valinomycin. Valinomycin, wani ionophore na halitta, yana nuna zaɓi na musamman ga ions na potassium fiye da sauran cations na gama gari kamar sodium (Na⁺), wanda yake da mahimmanci don ma'auni daidai a cikin matrices masu rikitarwa kamar jini ko cirewar ƙasa. Elektr ɗin yana aiki akan ƙa'idar potentiometric: lokacin da aka nutsar da shi a cikin samfurin, ɗaure ions na K⁺ a cikin hanyar haɗin membrane-mafita yana haifar da bambanci mai yuwuwa. Wannan yuwuwar, wanda aka auna akan electrode mai tsayayyen tunani, yana bin lissafin Nernst kuma yana da daidaiton logarithmically ga aikin ions na potassium.
