Screw Cuti

Kuyesa kwa COD ndi chizindikiro chabwino cha zoipitsa zopangidwa mu madzi otayika mafakitale okhala ndi matchatchi ndi zitsulo zolemera. Kuyesa kwa COD kumangothandizira kuyankha mwachangu kusintha zinthu zovuta zovuta zisanachitike. 

Mu mayeso amenewa opanda kanthu amagwiritsidwa ntchito m'malo mwa madzi osavomerezeka omwe amatchulidwa mu Malangizo a Corpond agwiritsiridwa ntchito. Zosawoneka bwino ndikuwonjezera madzi owoneka bwino kapena madzi osungunuka kupita ku chubu chopondapo ndikugawa chubu momwemonso kwa sample yamadzi.
Sikofunikira kukonzekera osavomerezeka nthawi iliyonse mayeso akuchitika. Chotsanuka chopanda tanthauzo chitha kukonzedwa sabata iliyonse ndikugwiritsa ntchito mobwerezabwereza ndi zitsanzo zonse zokonzedwa kuchokera ku gawo limodzi la machubu odzikonda. Zopanda kanthuzo ziyenera kusungidwa mumdima pakati pa kugwiritsa ntchito.

Kufunikira kwamankhwala kwa oxygen ndi mayeso ofunikira pakuwunika mtundu wa ma eyents ndi madzi otaya asanadutse. Mayeso a oxygen amafunikira (cod) amalosera za oxygen zofunikira ndipo amagwiritsidwa ntchito powunikira ndi kuwongolera zomwe zimachotsa ndalama, komanso kuwunika kasamalidwe ka mankhwala. Zovuta za kutulutsa kwamadzi kapena kuwononga madzi pa kulandira madzi kumanenedweratu chifukwa cha kufunafuna kwake kwa oxygen. Izi ndichifukwa choti kuchotsedwa kwa oxygen kuchokera ku madzi achilengedwe kumachepetsa kuthekera kwa moyo wam'madzi. Chiyeso cha COD chimachitika ngati chizolowezi cha ma labotore ogwiritsa ntchito zamadzi ndi makampani opanga mafakitale.

Ndi mayeso a kachizono couiren code, wogwiritsa ntchito aliyense amatha kupezeka mosavuta komanso mosavuta.
Nthawi yofunikira kuti muyeso muyeso zimafupikitsidwa kwambiri, makamaka pakuwunika ndi kuchuluka kwa mindandanda, ndikuchepetsa mphamvu.
Chubu choyesera cha cod chili ndi deto lokhazikika la regin. Chifukwa chake, kufufuza mopitirira kwamankhwala kwambiri kumapeweka ndipo chitetezo chantchito chimakhala bwino.

Tsatanetsatane wa mankhwala oxygen akufuna kuyesa:

2ML ya madzi kapena santeji ya Watse imawonjezeredwa ku chubu cha 16mmm miyambo yokhala ndi chimbudzi komanso chothandizira. Chubu chimasungidwa ndi polypropylene, ptfe yokhazikika ndikuwotcha mu digishi ya block ku 150C kwa maola awiri. Christovale ya lalanje ya lalanje imachepetsedwa ku chromishish yobiriwira. Mitundu yowunikira ya njira yoperewera ndi 5-160ppm (yoyesedwa pa 420nm).

Cold codests toptits imakhala ndi sulfuric acid ndi mankhwala ena, motero ma reagents ayenera kugwiritsidwa ntchito mosamala. Zomwe zili pachikuto ziyenera kutayidwa mogwirizana ndi zofuna za oyang'anira wamba.
Machubu awa ndi SGC yotsimikizika. Machubu awa amatha kugwiritsidwa ntchito kamodzi, kotero sangagwiridwenso ntchito.

Kuti mugwiritse ntchito chotenthetsera digito cha mayeso a cod, ikani kutentha pa chiwonetsero cha digito mpaka 150 ° C. Popanda ku akaunti yake iyenera kukhazikitsidwa pamtunda wapamwamba kwambiri kuposa momwe zafotokozedwera pamene izi zingayambitse chiwopsezo kudzera mu machubu a cood.

Oyenera ma cossimeter ndi kuyesa kits pamsika
Komanso oyeneranso kupangira zida
Mbale zosindikizidwa zotsekemera zokhala ndi zotsekemera
Kwezani moyo wa alumali kwa zaka zisanu
Ogwiritsidwa ntchito kumadzi am'madzi am'madzi; madzi otayika a mafakitale ndi njira yowongolera; Kuyesedwa kwa Madzi

Tsegulani Chuma cha COD, gwiritsani ngodya ndikuwonjezera pang'onopang'ono
2.0 ml ya mawonekedwe oyeserera kuchokera ku chubu chazinthu popanda kusakaniza kotero kuti zigawo ziwiri zosiyana
amapangidwa.
Screw Cap moyenera kuti muyese chubu, gwiritsitsani chubu ndi kapu, ikani chubu mu botolo lotetezeka ndikugwedezeka
(Chenjezo, kuyesa chubu kumakhala kotentha). Ikani chubu chotentha. Yambitsani dongosolo la kutentha.
Pambuyo pa 2 h kuchotsa chubu cha matenthedwe, lolani kuti kuziziritsa kukhosi ndikugwedeza pang'ono
Nthawi zingapo.
Oyera kunja kwa chubu ndi muyeso.
Sinthani komete mpaka zero pogwiritsa ntchito mtengo wopanda pake "wopanda pake"

Kufunikira kwamankhwala kwa oxygen ndi mayeso ofunikira pakuwunika mtundu wa ma eyents ndi madzi otaya asanadutse. Mayeso a oxygen amafunikira (cod) amalosera za oxygen zofunikira ndipo amagwiritsidwa ntchito powunikira ndi kuwongolera zomwe zimachotsa ndalama, komanso kuwunika kasamalidwe ka mankhwala. Zovuta za kutulutsa kwamadzi kapena kuwononga madzi pa kulandira madzi kumanenedweratu chifukwa cha kufunafuna kwake kwa oxygen. Izi ndichifukwa choti kuchotsedwa kwa oxygen kuchokera ku madzi achilengedwe kumachepetsa kuthekera kwa moyo wam'madzi. Chiyeso cha COD chimachitika ngati chizolowezi cha ma labotore ogwiritsa ntchito zamadzi ndi makampani opanga mafakitale.

Ndi mayeso a kachizono couiren code, wogwiritsa ntchito aliyense amatha kupezeka mosavuta komanso mosavuta.
Nthawi yofunikira kuti muyeso muyeso zimafupikitsidwa kwambiri, makamaka pakuwunika ndi kuchuluka kwa mindandanda, ndikuchepetsa mphamvu.
Chubu choyesera cha cod chili ndi deto lokhazikika la regin. Chifukwa chake, kufufuza mopitirira kwamankhwala kwambiri kumapeweka ndipo chitetezo chantchito chimakhala bwino.

Kuyesa kwa oxygen kumafunikira (cod) kumagwiritsidwa ntchito kwambiri ngati muyeso wa zopangidwa ndi zopangidwa ndi mpweya wambiri womwe umafunikira kuti agwiritse ntchito mankhwala, kutentha ndi nthawi inayake. Kuyesa kwa COD ndi chizindikiro chabwino cha zoipitsa zopangidwa mu madzi otayika mafakitale okhala ndi matchatchi ndi zitsulo zolemera. Kuyesa kwa COD kumangothandizira kuyankha mwachangu kusintha zinthu zovuta zovuta zisanachitike. Mbale za ku Lovibond ndi yogwirizana ndi mitundu yonse ya Lovibond ndi HaCH®.
