15-425 Uchungechunge, 12ml Sula I-Screw1 Borosilicate Glass Vial ene-PTFE silicone septa

Ukuhlolwa kwe-Chemical Oxygen Demand (COD) kusetshenziswa kabanzi njengesilinganiso sokungcoliswa kwezinto eziphilayo ngokunquma inani le-oxygen edingekayo ukuze kufakwe i-oxidation yezinhlobo ezincishisiwe ezihlanganisa izinto eziphilayo, kusampula yamanzi kusetshenziswa i-oxidizing ejenti ethile, izinga lokushisa kanye nokunciphisa isikhathi. Ukuhlolwa kwe-COD kuyinkomba engcono kakhulu yokungcola kwemvelo emanzini angcolile ezimbonini aqukethe ama-cyanide nezinsimbi ezisindayo. Ukuhlolwa kwe-COD kunikeza impendulo esheshayo ezimeni ezishintshayo ngaphambi kokuba kuthuthuke izinkinga ezibucayi. Izitsha ze-COD zika-Lovibond ziyahambisana nama-colorimeter OKUMBILI we-Lovibond ne-Hach®.

Vula ishubhu lokuhlola le-COD, libambe nge-engeli bese wengeza kancane
2.0 mL wesixazululo sesampula esenziwe ngaphambilini esivela kushubhu yokusabela ngaphandle kokuxuba ukuze izendlalelo ezimbili ezihlukene
kwakheka.
Faka isikulufu ikepisi ngokuvikelekile ukuze uhlole ishubhu, ubambe ishubhu ngekepisi, faka ishubhu ebhodleleni lokuphepha futhi unyakazise
(Qaphela, ishubhu lokuhlola liyashisa). Faka ishubhu endaweni yokushisa. Qala uhlelo lokushisisa.
Ngemva kwamahora angu-2 khipha ishubhu lokuhlola endaweni yokushisa, vumela ukuba liphole ekamelweni lokushisa futhi unyakazise kancane
izikhathi eziningana.
Hlanza ngaphandle kweshubhu lokuhlola futhi ulinganise.
Lungisa i-photometer ibe yiziro ngokusebenzisa inani elingenalutho elithi "NULL"

I-Aijiren ibikhiqiza i-15-425 Screw Neck Storage Vial kusukela ngo-2009 futhi isineminyaka engaphezu kweshumi ilapho.Siyakwamukela ukuthengwa kweVial Eshibhile ye-Screw Neck Storage Vial, izitsha ze-PP, izitsha zechromatography kanye nesihlungi seSiringe. Thola i-15-425 Screw Neck Storage Vial enabakhiqizi bekepisi nabahlinzeki abavela eChina. Singumkhiqizi ochwepheshe we-15-425 Screw Neck Storage Vial.

Ukuhlola amanzi e-Total Organic Carbon (TOC) akusabalulekile embonini yezemvelo. Ngezindlela zakamuva ze-USP, i-TOC manje isiyinkinga yanoma iyiphi imboni esebenzisa Amanzi Ahlanzekile Namanzi Omjovo. Izitsha ze-TOC ze-Aijiren Low Level zihlanzwa ngokukhethekile futhi zipakishwe ukuze kwehlise i-TOC ibe amazinga aphansi kakhulu ngangokunokwenzeka, iqinisekisa isizinda esiphansi sokuhlolwa kwakho.

I-TOC isifinyezo se-Total Organic Carbon. I-TOC Direct Method evela ku-Aijiren inikeza izindlela ezithembekile nezisebenzayo zezindawo zokuhlanza amanzi ukuze zivame ukukala ikhabhoni ephilayo ukuze kuthuthukiswe izinqubo zokwelashwa. Esikhundleni sokuthenga umhlaziyi we-TOC obizayo, ongokwesiko noma ukhiphe izinqumo ze-TOC elabhorethri yenkontileka, le ndlela inganikeza imiphumela ye-TOC - ngokunembile futhi engabizi - khona kanye endaweni yakho, futhi ngaphandle kwanoma iyiphi imfucuza eyingozi.

Ngokuhlolwa kweshubhu ye-Aijiren COD, umsebenzisi ngamunye angakwazi ukuthola kalula amanzi azwela kakhulu futhi anembile.
Isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ekuhlaziyweni okujwayelekile kanye nesilinganiso sochungechunge, kuyilapho kunciphisa kakhulu umsebenzi.
Ishubhu yokuhlola ye-COD iqukethe umthamo oqondile we-reagent. Ngakho-ke, inani lamakhemikhali eleqile liyagwenywa futhi nokuphepha komsebenzi kuyathuthukiswa.

Ukuhlolwa kwe-tube kokuhlaziywa kwe-photometric kukholisa ngokuphathwa kwawo kalula ngakho-ke kuyinketho yokuqala yokuhlaziywa kwenqubo, ilabhorethri kanye nenqubo. Ubuningi bokunemba nokunemba kunikezwa emiphumeleni yokulinganisa ngenxa yama-reagents afakwe umthamo wangaphambilini ku-16mm cuvettes nama-reagents engeziwe.

I-Aijiren ibambe iqhaza ekukhiqizeni ishubhu yokuhlola ye-COD ene-Caps iminyaka engaphezu kweshumi, sinolwazi olucebile ngokuphelele nezinqubo ezijwayelekile zokukhiqiza ishubhu yokuhlola ye-COD enekepisi, futhi singaqinisekisa ikhwalithi ephezulu yeshubhu lokuhlola le-COD elikhiqizwa i-Aijiren ngentengo efanelekile.

Izitsha zesampula zokugcina zisetshenziswa kakhulu ekugcinweni kwesampula nasekuthuthweni.

I-Screw Glass Vials yiziqukathi ezincane eziyisilinda ezenziwe ngengilazi ezihlonyiswe ngendlela yokuvala i-screw cap. Lezi zitsha zenzelwe ukugcina nokuvikela ngokuphephile izinto ezahlukahlukene, njengoketshezi noma amasampula aqinile.
Ukuvalwa kwe-screw cap yalezi zitsha iqukethe ikepisi elinentambo elingasonteka kalula livule futhi livale ibhodlela. Le ndlela yokuvala iqinisekisa ukuvala okuqinile, ukuvimbela ukuvuza noma ukungcoliswa kokuqukethwe. I-screw cap ngokuvamile inomugqa noma i-septum ngaphakathi ukuze inikeze ukuvala nokuvikela okwengeziwe.

Imininingwane Yokuhlolwa Kwesidingo Se-Chemical Oxygen:

U-2mL wesampula wamanzi noma we-watse wengezwa eshubhuni yengilazi engu-16mm equkethe into evuselela ukugaya ukudla kanye ne-catalyst. Ishubhu imbozwe nge-polypropylene, ikepisi elayishiwe ye-PTFE futhi ishisiswe ku-block digester ku-150C amahora angu-2. I-chromium ye-Hexavalent ewolintshi yehliswa ibe yi-chromium e-trivalent eluhlaza okwesibhakabhaka. Ibanga lokuhlaziya lendlela ye-spectrophotometric ngu-5-150ppm (kukalwa ku-420nm).

I-15-425 Screw Sample Storage Vials eyenziwe ngengilazi ye-borosilicate yekhwalithi ephezulu yokushisisa noma i-autoclaving, i-syringe esheshayo ukufinyelela kuma-reagents avaliwe ngokuphelele namazinga. I-Aijiren Sample Storage Vials itholakala ngosayizi ababili wokugcina, ukufudumeza kanye ne-autoclaving.

Kulokhu kuhlolwa kusetshenziswa i-reagent engenalutho esikhundleni sendawo evamile engenalutho yamanzi okukhulunywe ngayo emiyalweni evamile yokusebenza kwe-photometer. I-reagent blank ilungiswa ngokungeza amanzi akhishwe i-deionised noma a-distilled kushubhu le-reagent bese kugaywa ishubhu ngendlela efanayo neyesampula yamanzi.
Akudingekile ukulungisa i-reagent engenalutho njalo lapho ukuhlolwa kwenziwa. Ishubhu elingenalutho le-reagent lingase lilungiswe masonto onke futhi lisetshenziswe ngokuphindaphindiwe nawo wonke amasampuli alungiselelwe kusukela kuqeqebana lamashubhu asebenzayo. I-reagent engenalutho kufanele igcinwe ebumnyameni phakathi kokusetshenziswa.

Isitsha Sokugcina Isampula esikhiqizwe i-Aijiren silungele ukuhlaziywa kwemvelo nokugcinwa kwamasampuli. I-15-425 inamandla amabili ahlukene, i-8ml ne-12ml, ifanele izinhlobo ezahlukene zamasampula.

I-Aijiren isebenzisa izinto zokusetshenziswa zekhwalithi ephezulu ukwenza Ishubhu Lokuhlola elingu-16mm Lokuhlaziya Amanzi. Ukwaneliseka nokudumisa kwekhasimende kwenze i-Aijiren yaba ngenye yabakhiqizi abakhulu baselabhorethri abasebenzisekayo eningizimu yeChina. Okokuqala, i-Aijiren izogcina inhloso yokuqinisekisa ikhwalithi ye-16mm Test Tube Yokuhlaziya Amanzi.

Izitsha zengilazi ezikulungela, ezaziwa nangokuthi izitsha ezikulufa ezikulukulu noma izitsha ezingaphezulu kwezikulufu, iziqukathi ezincane ezenziwe ngengilazi ezinomshini wokuvala isikulufu. Lezi zitsha zivame ukusetshenziswa kumalabhorethri nakwezinye izilungiselelo zesayensi ukuze kugcinwe futhi kuthuthwe amasampula awuketshezi noma ayimpushana.

I-Aijiren Sample Storage Vial ivamise ukusetshenziselwa ukuhlaziya imvelo. Isitsha Sengilazi Esicacile singabona kangcono isimo sesampula. I-Amber Glass Vial ingamelana nokukhanya kwe-ultraviolet futhi ivikele izingxenye zamakhemikhali kusampula ezizwela ukukhanya kwe-ultraviolet.

Isidingo somoya-mpilo wamakhemikhali siwukuhlola okubalulekile kokuhlola ikhwalithi yamanzi alahlwayo kanye namanzi angcolile ngaphambi kokuba akhishwe. Ukuhlolwa kweChemical Oxygen Demand (COD) kubikezela isidingo somoya-mpilo kumfucumfucu futhi isetshenziselwa ukuqapha nokulawula okuphumayo, kanye nokuhlola ukusebenza kwezitshalo zokwelashwa. Umthelela wokuchitheka kwamanzi angcolile noma angcolile emanzini atholwayo ubikezelwa ngesidingo sawo somoya-mpilo. Lokhu kungenxa yokuthi ukukhishwa komoya-mpilo emanzini emvelo kunciphisa amandla awo okulondoloza impilo yasemanzini. Ngakho-ke ukuhlolwa kwe-COD kwenziwa njengenjwayelo kumalabhorethri ezinsiza zamanzi nezinkampani zezimboni.
