Na ua tseba hore na Sensor ea Electrochemical e sebetsa joang?

Bakeng sa lipotso tsena, pele re lokela ho tseba lintlha tse ling tsa motheo tse kang molao-motheo , likaroloana, mehato ea ts'ebetso

hape o hloka ho tseba mefuta e meng e tsebahalang ea li-electrochemical sensors. ebe o hlahloba lintlha ka tsela e latelang:

Li-sensor tsa electrochemical li sebelisoa haholo ho bona le ho lekanya lintho tse fapaneng tsa lik'hemik'hale ka ho sebelisa melao-motheo ea electrochemistry. Mona ke kakaretso ea kakaretso ea kamoo li sebetsang kateng:

1. Molao-motheo oa Motheo:

Li-sensor tsa electrochemical li sebetsa ka ho lekanya matla a motlakase kapa a hona joale a hlahang ka lebaka la karabelo ea lik'hemik'hale sebakeng sa electrode.

2. Likaroloana tsa Motheo:

* Working Electrode (WE): Mona ke moo karabelo ea electrochemical ea thahasello e etsahalang. Lintho tse bonahalang le bokaholimo ba elektrode ena li bohlokoa bakeng sa ts'ebetso ea sensor.
* Reference Electrode (RE): E fana ka monyetla o tsitsitseng oa litšupiso oo matla a motlakase a sebetsang a lekantsoeng.
* Counter Electrode (CE kapa Auxiliary Electrode): E phethela potoloho ea motlakase, e lumellang hore hona joale ho phalle pakeng tsa li-electrode tse sebetsang le tsa counter.
* Electrolyte: Sesebelisoa se tsamaisang motsamao oa li-ion le ho ts'ehetsa karabelo ea electrochemical ho li-electrode.

3. Mehato ea Ts'ebetso:

* Ho pepeseha ho Analyte: Ha molek'hule (kapa analyte) e pepesehetse electrode e sebetsang, e ba le karabelo ea electrochemical - ebang ke oxidized (e lahleheloa ke li-electrone) kapa e fokotsehile (e fumana li-electrone).
* Phetisetso ea Elektrone: Karabelo ena ea electrochemical e kenyelletsa phetiso ea lielektrone lipakeng tsa analyte le electrode, ho theha lets'oao la motlakase le lekantsoeng.
* Tekanyo ea Letšoao: Letšoao la motlakase le hlahisitsoeng (ebang ke phapang e ka bang teng kapa hona joale) le lekanyetsoa ho latela referense e tsitsitseng e fanoeng ke electrode ea referense.
* Tlhaloso ea Boitsebiso: Boholo ba pontšo ena ea motlakase bo amana ka ho toba le ho tsepamisa mohopolo oa mohlahlobi. Ka ho bapisa lets'oao le sekhahla sa calibration kapa ho sebelisa boits'oaro bo tsebahalang ba analyte, ho tsepamisa mohopolo ho ka khethoa.

4. Mefuta ea li-Sensors tsa Electrochemical:

* Li-Sensors tsa Potentiometric: Lekanya phapang e ka bang teng lipakeng tsa li-electrode tse sebetsang le tsa litšupiso. pH metres ke mehlala e tloaelehileng.
* Li-Sensors tsa Amperometric: Lekanya sephetho sa hajoale se hlahisoang ke karabelo ea electrochemical ea analyte ho eleketrode e sebetsang. Limithara tsa glucose hangata li sebelisa li-sensor tsa amperometric.
* Li-Sensors tsa Impedimetric: Lekanya phetoho kapa phetoho ea ho hanyetsa ka har'a sele ea electrochemical ha e sebelisana le analyte.
* Li-Sensors tsa Conductometric: Lekanya phetoho ea conductivity ea tharollo ea electrolyte ha u sebelisana le analyte.

5. Melemo ea Li-Sensors tsa Electrochemical:

* Kutlo e phahameng le ho khetha.
* Nako ea karabo e potlakileng.
* Bokhoni ba ho sebetsa maemong a metsi le khase.
* Bokhoni ba ho sebetsa ka lisampole tse litšila kapa tse mebala.
* Hangata e nkehang habonolo ebile e loketse tlhahlobo ea nako ea nnete.

6. Meeli:

* Li-sensor li ka silafatsoa kapa tsa chefo ke lintho tse silafatsang, tse amang tšebetso ea tsona.
* Ho hoholeha ha li-electrode tsa litšupiso ho ka baka liphoso.
* Tse ling li hloka ho lekoa nako le nako ho boloka ho nepahala.

Ka kakaretso, ts'ebetso ea li-sensor tsa electrochemical e ipapisitse le moralo o ikhethileng, lisebelisoa tse sebelisitsoeng, le mofuta oa karabelo ea electrochemical ea analyte e lebisitsoeng. Mefuta e mengata ea ts'ebeliso ea bona e tloha ho tlhokomelo ea tikoloho le tlhahlobo ea bongaka ho ea ho tiisetso ea boleng ba lijo le ho feta.
