I-Aijiren Autosampler Izitsha

Ama-COD Tubetests asetshenzisiwe aqukethe i-sulfuric acid eqinile namanye amakhemikhali, ngakho-ke ama-reagents kufanele aphathwe ngokucophelela. Okuqukethwe kwepayipi kufanele kulahlwe ngokuhambisana nezidingo zeziphathimandla zendawo.

IsiShayina (Sesiko)
25mm FTU Izitsha Zokuhlola

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.

Ishubhu yokuhlola ye-COD engu-16mm ekhiqizwa i-Aijiren isetshenziswa kakhulu ekuhlaziyeni amakhemikhali elabhorethri. U-Aijiren ukholelwa ukuthi i-COD Test Tube idinga izinto ezingavuthiwe zekhwalithi ephezulu kanye nobuchwepheshe obuthuthukisiwe ukuze iqedele ukukhiqiza, ngakho i-Aijiren ibheka kakhulu ukukhiqizwa kwe-COD Test Tube. U-Aijiren uke waba umakadebona emkhakheni wezinto ezisetshenziswayo ze-chromatography oneminyaka engama-20 yesipiliyoni sokukhiqiza. Usayigcinile inhloso yakhe yasekuqaleni futhi ubeka ukuthuthukiswa kwekhwalithi yomkhiqizo endaweni yokuqala.

Isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ekuhlaziyweni okujwayelekile kanye nesilinganiso sochungechunge, kuyilapho kunciphisa kakhulu umsebenzi.

Asetshenziselwa ukuhlola amanzi angcolile kamasipala; ukuhlolwa kwamanzi angcolile ezimbonini kanye nokulawula inqubo; ukuhlolwa kwamanzi kwemvelo
(Qaphela, ishubhu lokuhlola liyashisa). Faka ishubhu endaweni yokushisa. Qala uhlelo lokushisisa.

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.
Faka isikulufu ikepisi ngokuvikelekile ukuze uhlole ishubhu, ubambe ishubhu ngekepisi, faka ishubhu ebhodleleni lokuphepha futhi unyakazise

Lawa mashubhu okuhlola aqinisekisiwe nge-SGC. Lawa mashubhu angasetshenziswa kanye kuphela, ngakho awakwazi ukuphinda asetshenziswe.

Ukuze usebenzise i-heater yedijithali ukuhlola i-COD, setha izinga lokushisa kusibonisi esidijithali libe ngu-150°C. Akumele i-heater ibekwe ezingeni lokushisa eliphezulu kunalelo elishiwo njengoba lokhu kungase kubangele ingozi ngokwakhiwa komfutho kumashubhu e-COD. <\/p>

Ukuze usebenzise i-heater yedijithali ekuhloleni i-COD, setha izinga lokushisa kusibonisi esidijithali libe ngu-150°C. Akumele i-heater ibekwe ezingeni lokushisa eliphezulu kunalelo elishiwo njengoba lokhu kungase kubangele ingozi ngokwakhiwa komfutho kumashubhu e-COD.

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.

*Incazelo: Igama lomkhiqizo: 16mm Ishubhu Lokuhlola Lokuhlaziya Amanzi Umthamo: 10-15ML, PTFE Septa yokuvalwa kweshubhu lokuhlola elingu-16mm Isikulufa Esimhlophe Sekhephu ye-Polycarbonate, Okuvalekile, 12mL Sula ishubhu lokuhlola...
I-COD Test Tube ekhiqizwe i-Aijiren inamandla angu-10ml, 12ml, kanye no-15ml. Ubukhulu buyi-16 mm. Ivamise ukusetshenziselwa ukuhlola izinga lamanzi futhi iqukethe ama-reagents awuketshezi. Isetshenziswa kakhulu embonini ye-petroleum kanye nokuhlaziywa kwamakhemikhali.

I-Aijiren COD Test Tube incane ngosayizi futhi ilula ngesisindo. Ingahlolwa ngaphandle kwanoma iyiphi enye impahla yaselabhorethri kanye nochwepheshe; kuthatha imizuzu engu-3-5 kuphela ukuhlola isampula, ngaphandle kwezinto ezengeziwe noma amathuluzi, futhi kulula ukuyisebenzisa.
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.

Leli shubhu lokuhlola le-COD liklanywe ngokunemba nokusebenza engqondweni. Inesakhiwo esimangelengele esingamelana nobunzima bokuhlolwa kwe-COD, okuhlanganisa amazinga okushisa aphezulu kanye nokuchayeka kumakhemikhali ahlukahlukene.

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.

Ngakho-ke ukuhlolwa kwe-COD kwenziwa njengenjwayelo kumalabhorethri ezinsiza zamanzi nezinkampani zezimboni.

Ukusebenzisa kabusha amakepisi nezitsha kuvula amathuba okungcola, kusukela ku-solvent (uketshezi noma umhwamuko) ohlangana nezinto ze-septa kanye nomkhathi. Lokhu kungase kube nomthelela omubi kumiphumela yakho yokuhlaziya, okubangelwa ukungcoliswa kwesampula, ukusabela kwamakhemikhali, noma ukuhwamuka. Kokubili amaphutha ekhwalithi nenani angase abe umphumela, adinga isikhathi esiningi, ebizayo, futhi ekhungathekisayo nokuxazulula izinkinga nokusebenza kabusha.

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. 

Kuyaqapheleka ukuthi uma ama-COD Tubetests asetshenzisiwe aqukethe i-sulfuric acid eqinile namanye amakhemikhali, ama-reagents kufanele aphathwe ngokucophelela. Izinto ezisepayipini kufanele zilahlwe ngokuhambisana nezidingo zeziphathimandla zendawo. Lawa mashubhu angasetshenziswa kanye kuphela futhi awakwazi ukuphinda asetshenziswe.

Ishubhu yokuhlola ye-COD iqukethe umthamo oqondile we-reagent. Ngakho-ke, inani lamakhemikhali eleqile liyagwenywa futhi nokuphepha komsebenzi kuyathuthukiswa.

Ukuhlola i-COD kuyinkomba engcono kakhulu yokungcoliswa kwemvelo emanzini angcolile embonini aqukethe ama-cyanides nezinsimbi ezisindayo. Ukuhlola i-COD kunikeza impendulo esheshayo ezimweni ezishintshayo ngaphambi kokuba kuvele izinkinga ezibucayi.

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.
