Tshaj tawm ntawm Cod 16mm Kev Ntsuas Tubes Rau Dej Tshawb

Kaum Ib Hlis 19th, 2020

Cim npe: Cod-Tube COD-TEST-RAJ 16 hli-cod-vial Cod-vial

TusCod Xeem TubeTsim los ntawm Aijiren feem ntau siv rau kev kuaj cov dej ua tau zoo. Txhawm rau kom haum rau cov qauv sib txawv thiab cov khoom lag luam ntawm cov cav tov, Aijiren tau tshaj tawm cov raj loj loj. Lub caliber yog ib qho tsis zoo 16 hli, tab sis ob peb yog 9mL, 10mL, 12mL, 12mL thiab 15ml. Cov tsav tsheb ntsuas 9ML ntsuas muaj lub tiaj tiaj, lub sijhawm 10mL ntsuas lub hauv qab, thiab 12mL thiab 15ml cod Test muaj ib puag ncig.

TOC yog cov tsiaj ntawv luv ntawm cov organic carbon. Aijiren's Cod Xeem Tube Muab kev pab zoo rau cov tshuaj tsom xam kom zoo, thiab kev sim ua kom yooj yim rau cov khoom lag luam ກົນ organic kom tau txais cov khoom lag luam thiab kev sim, thiab cov txiaj ntsig kev ntsuas tau txais kuj yog qhov tseeb.

Tus Cod Xeem Tube Tsim los ntawm Aijiren feem ntau siv rau tshuaj oxygen thov kev tshuaj ntsuam. Cov txheej txheem muaj raws li hauv qab no: 2ml ntawm dej lossis dej tshiab ua piv txwv ntxiv rau 16 hli iav kab lis kev cai tub kab mob lub raj thiab catalyst. Npog lub raj nrog polypropylene lined polypropylene raj thiab cua sov nws nyob rau hauv ib thaiv zom zom ntawm 150 ° C rau 2 teev. Txiv kab ntxwv hexavalent chromium yog txo kom ntsuab ntau zaus chromium. Kev tsom xam ntau ntawm spectrophotometry yog 5-150ppm (ntsuas ntawm 420NM).

Cov tshuaj xav tau pa oxygen (COD) yog siv dav ua kev ntsuas ntawm cov tshuaj lom orgygen) hauv cov tshuaj ntsuab uas siv cov oxidant, thiab txo qhov kub thiab sijhawm. Cov tshuaj ntsuas cov pa oxygen thov tuaj yeem qhia tau zoo dua cov organic cov organic hauv kev siv dej khib nyiab hauv kev siv dej kom muaj cyanide thiab cov hlau hnyav. COD Kev Xeem tuaj yeem teb hloov pauv hloov pauv hloov ua ntej ua ntej cov teeb meem tseem ceeb tshwm sim.

Nrog tus aijiren Cod Xeem Tube, txhua tus neeg siv khoom tuaj yeem yooj yim ua cov dej tsis muaj tseeb thiab raug. Lub sijhawm xav tau rau txoj kev ntsuas ntsuas yog qhov luv luv, tshwj xeeb tshaj yog rau cov qauv tsom xam thiab ntsuas kev ntsuas cov haujlwm.

Tus cod ntsuas lub raj muaj cov tshuaj pleev qhov tseeb ntawm reagent. Yog li ntawd, cov khoom lag luam tshuaj ntau dhau yog zam thiab ua haujlwm kev nyab xeeb tau txhim kho.
