Nkumuhanga wa laboratoire, kimwe mubikoresho byingenzi uzakenera ni metero ya pH. Iki gikoresho kirakomeye mugushakisha ibisubizo nyabyo byo gusesengura imiti. Muri iki kiganiro, tuzaganira kuri metero pH icyo aricyo, uko ikora, nakamaro kayo mu isesengura rya laboratoire.
Metero pH ni iki?
Imetero ya pH nigikoresho cya elegitoronike gikoreshwa mugupima pH (acide cyangwa alkaline) yumuti. Ifite iperereza ryinjijwe mubisubizo bigeragezwa, kandi igikoresho gipima ubushobozi bwamashanyarazi hagati ya probe na electrode yerekana. Ubu bushobozi noneho buhindurwa mugusoma pH.
Nigute metero ya pH ikora?
Imetero ya pH ikora ishingiye ku ihame rya electrochemie. Iperereza ririmo electrode yikirahure, ikaba ari ikirahure cyoroshye, cyunvikana cyibirahure gisubiza impinduka muri acide cyangwa alkalinity yumuti. Ibibyimba bisizwe hamwe nibikoresho bidasanzwe bitanga ingufu z'amashanyarazi mugihe uhuye na acide cyangwa igisubizo cyibanze. Ku rundi ruhande, electrode yerekana, itanga ingufu zamashanyarazi zihamye zikoreshwa nkugereranya nubushobozi butangwa na electrode yikirahure. Itandukaniro mubushobozi bwamashanyarazi hagati ya electrode zombi noneho bipimwa na metero pH, hanyuma kubara pH birabaze.
Akamaro ka metero ya pH muri Analyse ya Laboratoire
Imetero ya pH nigikoresho gikomeye mugusesengura laboratoire, kandi ikoreshwa muburyo butandukanye, harimo:
1. Kwipimisha Ibidukikije
Mu gupima ibidukikije, metero pH zikoreshwa mugupima pH yubutaka, amazi, numwuka. Aya makuru ni ngombwa mu gusuzuma ubuziranenge bw’ibidukikije no kumenya inkomoko y’umwanda.
2. Gupima ibiryo n'ibinyobwa
Mu nganda zibiribwa n'ibinyobwa, metero pH zikoreshwa mugukurikirana acide cyangwa alkaline yibicuruzwa bitandukanye. Aya makuru ni ingenzi mu kwemeza ko ibicuruzwa bifite umutekano ku bicuruzwa kandi byujuje ibisabwa n'amategeko.
3. Isesengura rya farumasi
Mu isesengura rya farumasi, metero pH zikoreshwa mugupima pH yimiti. Aya makuru ni ngombwa mu kwemeza ko imiti ihamye kandi ikora neza.
4. Isesengura ryimiti
Mu isesengura ry’imiti,metero pHzikoreshwa mugupima pH yibisubizo, harimo acide na base. Aya makuru ni ingenzi mukumenya igisubizo cyibisubizo no kumenya ibisubizo byose bishobora kubaho.
Ubwoko bwa pH Ibipimo
Hariho ubwoko bubiri bwingenzi bwa metero pH: kugereranya na digitale.
Ikigereranyo pH Ibipimo
Analog pH metero nubwoko bwa metero ya pH, kandi bakoresha urushinge nubunini kugirango berekane gusoma pH. Izi metero zihenze kuruta metero ya digitale, ariko ntizisobanutse neza kandi ntisobanutse neza.
Ibipimo bya pH
Imibare ya pH ni ubwoko bugezweho bwa metero ya pH, kandi bakoresha ecran ya LCD kugirango berekane gusoma pH. Izi metero zirasobanutse neza kandi zisobanutse kuruta metero zisa, ariko zirazimvye.
pH Kugereranya Ibipimo
Calibration nintambwe yingenzi mu kwemeza ko metero pH itanga ibyasomwe neza kandi neza. Calibration ikubiyemo guhindura metero kugirango ihuze na pH yumuti uzwi. Kugirango uhindure metero ya pH, uzakenera urutonde rwibisubizo bisanzwe bifite agaciro ka pH. Ibi bisubizo bigomba gukwirakwiza urwego rwa pH uzagerageza. Imetero ya pH ibanza guhindurwamo aside irike cyangwa ibanze isanzwe, hanyuma igahinduka ibisubizo bisigaye kugirango hongerwe pH.
Kubungabunga ibipimo bya pH
Kubungabunga neza metero pH ningirakamaro mugutanga ibisobanuro nyabyo kandi byuzuye. Zimwe mu nama zo kubungabunga metero pH zirimo:
- Isuku isanzwe ya probe na electrode
- Kubika metero ya pH ahantu humye kandi hakonje
- Guhindura metero buri gihe
- Gusimbuza probe na electrode nkuko bikenewe
