PP cap yog tsim nyob rau hauv ib daim molded ntawm inert, tshuaj tiv thaiv polyethylene. Lub starburst slits tso cai rau rab koob nkag tau yooj yim. Tsim los rau cov ntawv thov siab, tshwj xeeb tshaj yog nyob rau hauv LCMS Market, purity ntawm no cap rau extractables yog zoo hauv qab picogram ntau yam. Qhov no high-grade polyethylene tsis muaj teeb meem paug PTFE\ / Silicone septa qhia nyob rau theem qis ntawm kev tshawb pom, thaum tseem sealing zoo heev.

2mL ntawm cov dej los yog watse dej coj mus kuaj yog ntxiv rau 16 hli iav kab lis kev cai raj uas muaj cov zom zom reagent thiab catalyst. Lub raj yog capped nrog ib tug polypropylene, PTFE lined cap thiab rhuab nyob rau hauv lub block digester ntawm 150C rau 2 teev. Cov txiv kab ntxwv Hexavalent chromium raug txo qis rau ib qho ntsuab ntsuab trivalent chromium. Kev ntsuas ntau yam rau txoj kev spectrophotometric yog 5-150ppm ( ntsuas ntawm 420nm).

Kev Ntsuas Tshuaj Oxygen Demand (COD) yog dav siv los ntsuas cov kab mob sib kis los ntawm kev txiav txim siab txog cov pa oxygen uas xav tau rau oxidation ntawm cov tsiaj uas txo qis xws li cov organic teeb meem, hauv cov qauv dej uas siv cov tshuaj oxidizing tshwj xeeb, kub thiab sijhawm txo. Kev kuaj COD yog qhov qhia tau zoo dua ntawm cov pa phem hauv cov dej khib nyiab uas muaj cyanide thiab cov hlau hnyav. Kev kuaj COD muaj peev xwm teb tau sai rau cov kev hloov pauv ua ntej cov teeb meem tseem ceeb tshwm sim.

Lub 16 hli COD Test Tube yog ib lub iav tshwj xeeb uas tsim los rau kev sim tshuaj Oxygen Demand (COD) hauv chav kuaj. Nws muaj txoj kab uas hla ntawm 16 hli, muab qhov chaw txaus rau kev sau thiab tshuaj xyuas. Lub raj yog ua los ntawm cov iav zoo, ua kom cov kav ntev thiab cov tshuaj lom neeg sib raug zoo rau kev ntsuas COD raug thiab txhim khu kev qha.

yog tsim tshwj xeeb rau kev sim tshuaj Chemical Oxygen Demand (COD), uas yog ib qho tseem ceeb ntawm kev ntsuas dej zoo. Nws yog ua los ntawm cov iav zoo kom pom tseeb thiab tshuaj tiv thaiv. Lub raj yog 16mm nyob rau hauv txoj kab uas hla, muab lub ntim zoo rau kev soj ntsuam cov qauv. Nws feem ntau yog muag hauv pob khoom ntawm ntau lub raj, tso cai rau kev sim ua haujlwm zoo.

Hauv qhov kev sim no, ib qho reagent blank yog siv los hloov cov dej ib txwm muaj nyob rau hauv cov lus qhia dav dav ntawm photometer. Lub reagent dawb paug yog npaj los ntawm kev ntxiv deionised los yog distilled dej rau lub raj reagent thiab tom qab ntawd zom cov raj hauv tib yam li cov qauv dej.

Lub COD xeem raj no yog tsim los nrog precision thiab functionality nyob rau hauv lub siab. Nws nta kev tsim kho rugged uas tuaj yeem tiv taus qhov nruj ntawm COD kuaj, suav nrog kev kub siab thiab raug rau ntau yam tshuaj.
Kev kuaj COD yog qhov qhia tau zoo dua ntawm cov pa phem hauv cov dej khib nyiab uas muaj cyanide thiab cov hlau hnyav. Kev kuaj COD muaj peev xwm teb tau sai rau cov xwm txheej hloov ua ntej teeb meem loj.

Reusing caps thiab vials qhib qhov muaj peev xwm ntawm kev sib kis, los ntawm cov kuab tshuaj (kua lossis vapor) cuam tshuam nrog cov khoom siv septa nrog rau cov cua. Qhov no tuaj yeem cuam tshuam rau koj cov txiaj ntsig kev soj ntsuam, ua rau cov qauv paug, tshuaj tiv thaiv, lossis evaporation. Ob qho tib si zoo thiab ntau qhov yuam kev tuaj yeem ua rau, yuav tsum tau siv sijhawm ntev, kim, thiab kev ntxhov siab rau kev daws teeb meem thiab rov ua haujlwm.

COD Test Tube yog ua los ntawm borosilicate iav, uas tuaj yeem txo cov pH hloov thiab cov kab mob uas tuaj yeem tawm ntawm cov iav dej qab zib. Cov iav digestion xeem raj tuaj yeem siv rau kev tsom xam ntawm qhov kub siab tshaj 130 degrees Celsius. Nws yog tsim los ntawm kev sim cia rau ntau yam kev siv dav dav thiab tuaj yeem tuav yuav luag txhua yam.

Kev xav tau tshuaj lom neeg cov pa oxygen yog qhov tseem ceeb rau kev ntsuas qhov zoo ntawm cov dej ntws thiab cov dej khib nyiab ua ntej tso tawm. Qhov Kev Ntsuas Tshuaj Oxygen Demand (COD) ntsuas ntsuas qhov xav tau ntawm cov pa oxygen ntawm cov dej ntws tawm thiab siv rau kev saib xyuas thiab tswj cov paug tawm, thiab ntsuas kev kho cov nroj tsuag kev ua haujlwm. Qhov cuam tshuam ntawm cov dej ntws los yog cov dej khib nyiab tawm ntawm cov dej tau txais yog kwv yees los ntawm nws qhov xav tau oxygen. Qhov no yog vim tias kev tshem tawm cov pa oxygen los ntawm cov dej ntuj txo nws lub peev xwm los txhawb nqa lub neej hauv dej. Kev kuaj COD yog li ntawd tau ua raws li niaj hnub hauv cov chaw soj nstuam ntawm cov dej siv dej thiab cov tuam txhab lag luam.
