Fluorescence yashegeshe metero ya ogisijeni ni igikoresho gikoreshwa mu gupima ubunini bwa ogisijeni yashonze mu mazi. Umwuka wa ogisijeni ni kimwe mu bintu by'ingenzi mu mibiri y'amazi. Ifite ingaruka zikomeye ku mibereho no kubyara ibinyabuzima byo mu mazi. Ni kimwe kandi mu bipimo by'ingenzi bipima ubuziranenge bw'amazi. Metero ya fluorescence yashonze metero ya ogisijeni igena umwuka wa ogisijeni ushonga mumazi mugupima ubukana bwikimenyetso cya fluorescence. Ifite ibyiyumvo bihanitse kandi byukuri kandi ikoreshwa cyane mugukurikirana ibidukikije, gusuzuma ubuziranenge bw’amazi, ubworozi bw’amazi n’indi mirima. Iyi ngingo izerekana mu buryo burambuye ihame ryakazi, imiterere yimiterere, imikoreshereze nogukoresha fluorescence yashonze metero ya ogisijeni mumirima itandukanye.
1. Ihame ry'akazi
Ihame ryakazi rya fluorescence yashonze metero ya ogisijeni ishingiye kumikoranire ya molekile ya ogisijeni nibintu bya fluorescent. Igitekerezo cyibanze ni ugushimisha ibintu bya fluorescente kuburyo ubukana bwikimenyetso cya fluorescente basohora kijyanye nubushakashatsi bwa ogisijeni yashonze mumazi. Ibikurikira nubusobanuro burambuye bwihame ryakazi rya fluorescence yashonze metero ya ogisijeni:
1. Ibi bintu bya fluorescent bifite ubukana bwinshi bwa fluorescence mugihe habuze ogisijeni, ariko mugihe ogisijeni ihari, ogisijeni izahindura imiti hamwe nibintu bya fluorescent, bigatuma ubukana bwa fluorescence bugabanuka.
2. Inkomoko yumucyo usanzwe ni LED (urumuri rusohora diode) cyangwa laser yuburebure bwihariye. Uburebure bwumurabyo utanga urumuri rusanzwe rwatoranijwe murwego rwo kwinjiza ibintu bya florescente.
3. Detector ya Fluorescence: Bitewe nigikorwa cyumucyo ushimishije, ibintu bya fluorescent bizasohora ikimenyetso cya fluorescence, ubukana bwacyo bukaba butandukanye cyane nubushakashatsi bwa ogisijeni yashonze mumazi. Fluorometrike ya elegitoronike yashonze ifite ibikoresho bya fluorescence kugirango bipime ubukana bwiki kimenyetso cya fluorescent.
4. Agaciro ubusanzwe kagaragarira muri miligarama kuri litiro (mg / L).
2. Imiterere yimiterere
Imiterere yimiterere ya fluorescence yashonze metero ya ogisijeni mubisanzwe ikubiyemo ibice byingenzi bikurikira:
1. Umutwe wa Sensor: Umutwe wa sensor nigice cyo guhura nicyitegererezo cyamazi. Mubisanzwe birimo fibre ya fluorescent optique cyangwa diafragm ya fluorescent. Ibi bice bikoreshwa muguhuza ibintu bya fluorescent. Umutwe wa sensor usaba igishushanyo cyihariye kugirango umenye neza ko ibintu bya fluorescent bihura neza nicyitegererezo cyamazi kandi ntibibangamiwe numucyo wo hanze.
2. Inkomoko yumucyo wibyishimo: Inkomoko yumucyo usanzwe iba iri mugice cyo hejuru cyigikoresho. Ihereza urumuri rwo kwishima mumutwe wa sensor ikoresheje fibre optique cyangwa fibre optique kugirango ishimishe ibintu bya fluorescent.
3. Ikimenyetso cya Fluorescence: Ikimenyetso cya fluorescence giherereye mugice cyo hepfo cyigikoresho kandi gikoreshwa mugupima ubukana bwikimenyetso cya fluorescence kiva mumutwe wa sensor. Ibyuma bya Fluorescence mubisanzwe birimo fotodiode cyangwa umuyoboro wa Photomultiplier, uhindura ibimenyetso bya optique mubimenyetso byamashanyarazi.
4. cyangwa igikoresho cyo gufata amakuru.
5. ibipimo byo kwibanda.
6. Kwerekana no gukoresha interineti: Fluorescence yashegeshwe na metero ya ogisijeni isanzwe iba ifite ibikoresho byifashisha-byerekanwa hamwe n’imikorere yo kwerekana ibisubizo byo gupima, gushiraho ibipimo no gukoresha igikoresho.
3. Uburyo bwo gukoresha
Ibipimo bya ogisijeni ya elegitoronike ikoresheje metero ya ogisijeni ya fluorescence yashizemo intambwe zikurikira:
1. Gutegura ibikoresho: Banza, menya neza ko igikoresho kiri mumikorere isanzwe. Reba neza ko urumuri rutanga urumuri hamwe na detector ya fluorescence ikora neza, isaha nitariki igikoresho cyakorewe, kandi niba ibintu bya fluorescent bigomba gusimburwa cyangwa gusubirwamo.
2. Icyegeranyo cy'icyitegererezo: Kusanya icyitegererezo cy'amazi kugirango gipimwe kandi urebe neza ko icyitegererezo gifite isuku kandi kitarimo umwanda n'ibibyimba. Nibiba ngombwa, akayunguruzo karashobora gukoreshwa mugukuraho ibintu byahagaritswe nibintu bito.
3. Kwishyiriraho Sensor: Shira byuzuye umutwe wa sensor mucyitegererezo cyamazi kugirango umenye neza hagati yibintu bya fluorescent nicyitegererezo cyamazi. Irinde guhura hagati yumutwe wa sensor hamwe nurukuta rwa kontineri cyangwa hepfo kugirango wirinde amakosa.
4. Tangira gupima: Hitamo Gutangira gupima kurwego rwo kugenzura igikoresho. Igikoresho kizahita gishimisha ibintu bya fluorescent kandi bipime ubukana bwikimenyetso cya fluorescent.
5. Kwandika amakuru: Nyuma yo gupima birangiye, igikoresho kizerekana ibisubizo byapimwe bya ogisijeni yashonze. Ibisubizo birashobora kwandikwa mububiko bwubatswe kubikoresho, cyangwa amakuru ashobora koherezwa mubikoresho byo hanze kugirango abike kandi abisesengure.
6. Gusukura no kubungabunga: Nyuma yo gupimwa, sukura umutwe wa sensor mugihe kugirango wirinde ibisigazwa bya fluorescent cyangwa umwanda. Hindura igikoresho buri gihe kugirango ugenzure imikorere yacyo kandi itajegajega kugirango urebe ibisubizo nyabyo byo gupima.
4. Imirima yo gusaba
Fluorescence yashonze metero ya ogisijeni ikoreshwa cyane mubice byinshi. Ibikurikira nimwe mubice byingenzi byo gusaba:
1. Gukurikirana ibidukikije: Fluorescence ya metero ya ogisijeni yashonze ikoreshwa mugukurikirana imyuka ya ogisijeni yashonze mu mazi asanzwe, inzuzi, ibiyaga, inyanja n’andi mazi kugira ngo isuzume ubwiza bw’amazi y’amazi n’ubuzima bw’ibinyabuzima.
2. Ubworozi bw'amafi: Mu buhinzi bw'amafi na shrimp, umwuka wa ogisijeni ushonga ni kimwe mu bintu by'ingenzi. Fluorescence yashonze metero ya ogisijeni irashobora gukoreshwa mugukurikirana imyuka ya ogisijeni yashonze mu byuzi byororoka cyangwa mu mazi kugira ngo inyamaswa zororerwa zibeho kandi zikure. .
3. Gutunganya amazi: Fluorescence yashegeshe metero ya ogisijeni irashobora gukoreshwa mugukurikirana imyuka ya ogisijeni yashonze mugihe cyo gutunganya amazi mabi kugirango amazi yanduye yujuje ubuziranenge.

Fluorescence yashonze metero ya ogisijeni ni igikoresho cyo hejuru, cyunvikana cyane gikoreshwa mugupima umwuka wa ogisijeni ushonga mumazi. Ihame ryarwo rishingiye ku mikoranire y’ibintu bya fluorescent na ogisijeni, kandi bifite uburyo bwinshi bukoreshwa, harimo gukurikirana ibidukikije, ubworozi bw’amazi, gutunganya amazi, ubushakashatsi bwo mu nyanja n’ubushakashatsi bwa laboratoire. Kubera iyo mpamvu, fluorescence yashonze metero ya ogisijeni igira uruhare runini mukubungabunga ibidukikije by’amazi no kurinda umutungo w’amazi.
Lianhua ishobora gutwara fluorescent yamenetse igikoresho cya ogisijeni LH-DO2M (V11) ikoresha ibyuma bitagira umuyonga electrode ifunze neza, hamwe na IP68 idafite amazi. Biroroshye gukora kandi ni umufasha ukomeye mugushakisha imyanda, amazi mabi n'amazi ya laboratoire. Ikigereranyo cyo gupima ogisijeni yashonze ni 0-20 mg / L. Ntibikenewe ko wongera electrolyte cyangwa kalibrasi kenshi, bigabanya cyane amafaranga yo kubungabunga.
