Ama-vials angu-Chemigen)iyithuluzi elibalulekile ekuhlolweni kwezemvelo, ikakhulukazi ngokuhlola okuqukethwe kwe-organic kwamasampula wamanzi. Lezi zinhlaka zisetshenziselwa ukunqunywa kwesidingo se-oxygen yamakhemikhali (i-cod) ezinhlotsheni ezahlukahlukene zamanzi, njengamanzi angaphezulu, amanzi angaphansi komhlaba, indle yendle, kanye namanzi okugaya kwezimboni, lapho kutholakala khona ukugaya. Ayilungele ukuhlaziywa kwamasampula wamanzi nge-chloride ion okuqukethwe okudlula okungama-30mg \ l.

Ngeminye imininingwane ngamashubhu wokuhlola ama-COD kanye nezicelo zawo ekuhlaziyweni kwamanzi, bhekani kulesi sihloko:"Yeka ukuthi ishubhu lokuhlola i-COD lisetshenziswa kanjani ekuhlaziyweni kwamanzi."

Izici ze-mercury yokugaya i-cod

I-Mercury-free digeges vials yakhelwe ukuqeda ubungozi obuhambisana ne-mercury, i-anobuthi yensimbi enobuthi ngokwesiko esetshenziswe ekuhlolweni kwe-COD. Esikhundleni salokho, la ma-reagent vials asebenzisa amanye ama-reagents ahambisana nemithetho yezemvelo futhi agcine ukusebenza kahle.

Ama-reagents alinganiswe kwangaphambili:

I-vial ngayinye iqukethe ukushintshwa kokugaya kwangaphambi kokulinganiswa okuhambisana namabanga athile ama-cod (amabanga aphezulu aphansi, aphezulu, kanye ne-mercury-free). Lo mklamo wenza lula inqubo yokuhlola, yehlisa isidingo sezilinganiso zezandla, futhi unciphise ukuvezwa kwamakhemikhali ayingozi.

Ukulupheka:

Lezi zinhlaka zihambisana nemishini yelabhoratri ejwayelekile, kufaka phakathi izinhlobo ezahlukahlukene zokugaya nama-spectrophotometer asetshenziswa kakhulu kuma-laboratories ezemvelo.

I-Seating Mechanism:

Ama-vialsImvamisa inezinketho zokuvikelwa kokubopha, ezifana nezinsimbi, ukuvikela ukuvuza nokungcola ngesikhathi sokugcina nokuhlaziywa.

Izinzuzo zokusebenzisa ama-vials e-mercury

1. Akukho ukulungiswa kwe-realent okudingekayo

Enye yezinzuzo ezibaluleke kakhulu zokusebenzisa i-reagents yokugaya kwangaphambi kokulinganiswa kwangaphambi kokuqedwa kokulungiswa kwe-reagent isikhathi. Ngezindlela zokuhlola izivivinyo zendabuko, abahlaziyi kumele balinganise ngokucophelela futhi baxube amakhemikhali ahlukahlukene, abasebenza kanzima futhi athambekele emaphutheni. Nge-VIALS elinganiswe ngaphambi kwesikhathi, ama-reagents asevele etholakala kwi-vial, futhi umsebenzisi udinga kuphela ukwengeza isampula yamanzi ngaphandle kokulungiselela. Lokhu akugcini nje okwesindisa isikhathi, kepha futhi kunciphisa ubungozi bokunganembile okuhambisana nezilinganiso zezandla.

2. Okuncishisiwe engcupheni yokungcola

Ukuphatha ama-vials amaningi kukhulisa amathuba okungcola, okungathinta imiphumela yokuhlola. Kulinganiswe kwangaphambili ukuzama Ama-vials anciphise le ngozi ngokukhawulela inani lezikhathi ama-reagents avezwa umoya noma adluliselwe phakathi kweziqukathi. I-vential ngayinye ye-COD ivaliwe ngaphambi kokusetshenziswa, ukugcina ubuqotho be-reagents futhi buqinisekise ukuthi bakhululekile ukungcoliswa kuze kube bayadingeka ukuze bahlaziywe.

3. Ukuhamba komsebenzi okuqondisiwe

UkusebenzisaAma-vials alinganiselwe alinganiselwekungenza ukuhamba komsebenzi ebhularatri kubekwe ngcono kakhulu. Abahlaziyi bangangeza ngokushesha amasampula ku-vial, basetha, bese beyibeka endaweni yokugaya ngaphandle ngaphandle kokusetha okwengeziwe kwe-glassware noma imishini yokuxuba ye-realent. Lokhu kusebenza kuzuzisa ikakhulukazi ama-laboratories angenayo adinga ukucubungula amasampula amaningi ngasikhathi sinye.

Ukuqonda okujulile kokuthi ama-cod vials asebenza kanjani ekuhlolweni kwamanzi, sicela ubheke kule ndatshana:"Umgomo osebenzayo we-cod vial."

Izicelo ekuhlolweni kwezemvelo

Ukuhlolwa kwekhwalithi yamanzi:

I-Mercury-Free COD yokugaya ama-vials isetshenziswa kabanzi ezindaweni zokuhlola ukubheka amazinga okungcosa ama-organic emanzini angaphezulu, amanzi angcolile kanye nokuphuza amanzi. Kusebenza emanzini angaphezulu komhlaba, amanzi aphansi komhlaba Izilinganiso ezinembile ze-COD zisiza ekuhloleni ukusebenza kwezinqubo zokwelashwa kwamanzi amdaka kanye nokuhambisana nemithetho yezemvelo.

Izihloko Zocwaningo:

Ososayensi bezemvelo basebenzisa lezi zinhlamvu zocwaningo ukuze bahlole imiphumela yokungcoliswa okuhlukahlukene kwemvelo yemvelo yasemanzini. Amandla okulinganisa ngokunembile udaba lwe-organic kusiza ukuqonda amabhayisekili anomsoco kanye nemvelo yemvelo.

Ukuqapha Kwezimboni:

Izimboni ezikhipha amanzi angcolile ezinhlanganweni zikaMasipala zivame ukusebenzisa ukuhlolwa kwe-COD ukuqapha ikhwalithi yamanzi angcolile awo. I-Mercury-free digesges tushibes anikeza indlela ephephile yokuqinisekisa ukuhambisana nezimvume zokukhipha.

Ufuna ukwazi kabanzi nge-COD Test Tube, sicela uhlole le ndatshana: I-COD Test Tube nge-PP Screw cap yokuhlaziywa kwamanzi

Ukugcina

I-Mercury-free cod yokugaya ama-cod umele intuthuko ebalulekile kubuchwepheshe bokuhlola imvelo, enikeza enye indlela ephephile yezinqubomgomo zendabuko eziqukethe izintambo zemvelo. Ukusebenziseka kalula kokusebenzisa, ukunemba, kanye nokuhambisana nokwenza kube yithuluzi elibaluleke kakhulu ezindaweni zokuhlinzekwa kwekhwalithi yamanzi. Ngokukhathazeka okwandayo ngezinkinga zezemvelo, ukwamukelwa kwezixazululo ezintsha ezinjengalezi kuzodlala indima enkulu ekuthuthukiseni imikhuba esimeme ocwaningweni lwesayensi nasembonini.
