Nūhou - He aha ka ʻokoʻa ma waena o kahi electrode pH hui hoʻokahi a me ka pālua?

ʻOkoʻa nā electrodes PH ma nā ʻano like ʻole; mai ke ʻano o ka piko, ka hui ʻana, ka mea a me ka hoʻopiha. ʻO kahi ʻokoʻa nui inā he hui hoʻokahi a pālua paha ka electrode.

Pehea e hana ai nā electrodes pH?
Hana nā electrodes pH hui pū ʻia ma ka loaʻa ʻana o kahi hapalua cell sensing (uea kālā i uhi ʻia e AgCl) a me kahi hapalua cell kuhikuhi (uea electrode kuhikuhi Ag/AgCl), pono e hoʻohui ʻia kēia mau ʻāpana ʻelua e hoʻopau i kahi kaapuni i mea e loaʻa ai i ka mika kahi heluhelu pH. ʻOiai ke ʻike nei ka hapalua cell sensing i ka loli o ka pH o ka hopena, ʻo ka hapalua cell kuhikuhi he hiki ke kuhikuhi paʻa. Hiki i nā electrodes ke hoʻopiha ʻia i ka wai a i ʻole ka gel. Hoʻokumu kahi electrode hui wai i kahi hui me kahi ʻili lahilahi o ka hoʻopiha hoʻopihapiha ma ka piko o ka probe. Loaʻa iā lākou kahi hana pamu e hiki ai iā ʻoe ke hana i kahi hui hou no kēlā me kēia hoʻohana. Pono lākou e hoʻopiha hou ʻia akā hāʻawi i ka hana maikaʻi loa e hoʻonui ana i ke ola, ka pololei a me ka wikiwiki o ka pane. Inā mālama ʻia kahi hui wai e loaʻa kahi ola mau loa. Hoʻohana kekahi mau electrodes i kahi electrolyte gel ʻaʻole pono e hoʻopiha ʻia e ka mea hoʻohana. ʻO kēia ka mea e lilo ai lākou i koho ʻoi aku ka fussfree akā e kaupalena ia i ke ola o ka electrode i kahi o 1 makahiki inā mālama pono ʻia.

ʻO ka Hui Pālua - loaʻa i kēia mau electrodes pH kahi alahaka paʻakai hou e pale aku i nā hopena ma waena o ka hopena hoʻopiha electrode a me kāu laʻana e hōʻino ai i ka hui electrode. Pono lākou e hoʻāʻo i nā laʻana i loaʻa nā protein, nā metala kaumaha a i ʻole nā sulphides

Hoʻokahi Huina - no nā noi hana maʻamau kēia no nā laʻana e ālai ʻole ai i ka huina.

He aha ke ʻano o ka electrode pH e pono iaʻu e hoʻohana?
Inā loaʻa i kahi hāpana nā protein, sulfites, nā metala kaumaha a i ʻole nā buffers TRIS, hiki i ka electrolyte ke hana me ka hāpana a hana i kahi precipitate paʻa e ālai ana i ka hui porous o kahi electrode a hoʻōki i kāna hana. ʻO kēia kekahi o nā kumu maʻamau o ka "electrode make" a mākou e ʻike pinepine ai.

No kēlā mau laʻana, pono ʻoe i kahi hui pālua - hāʻawi kēia i kahi pale hou aʻe mai kēia hanana, no laila e loaʻa iā ʻoe kahi ola maikaʻi loa mai ka electrode pH.
