I-Cod reagent vial isho uhlobo oluthile lwe-vial olusetshenziswa ekuhlaziyweni kwamakhemikhali ukukala isidingo sesampula yamakhemikhali. I-COD yisilinganiso senani le-oksijini elidingekayo kumakhemikhali amakhemikhali ama-organic ne-inorganic akhona kwisampula yamanzi.
I-POD reagent vial iqukethe amakhemikhali adingekayo nama-reagents ukwenza lula ukusabela kwe-oxidation. Ngokuvamile kufaka phakathi ingxubevange ye-oxidizing agents eqinile, efana ne-potassium dichromate noma i-potassium permanganate, kanye namanye amakhemikhali asiza ukuqala futhi asheshise inqubo ye-oxidation.

I-Cod yokugaya i-Cod yiziqukathi ezikhethekile ezisetshenziswa ekuhlaziyweni kwamakhemikhali zokunquma isidingo se-oxygen yamakhemikhali (i-cod) yesampula yamanzi. I-COD iyisilinganiso senani le-oksijini elidingekayo kumakhemikhali amakhemikhali ama-organic kanye nama-inforganic akhona emanzini.
Lezi zinhlaka ngokuvamile zenziwa ngengilazi esezingeni eliphakeme noma ingilazi ye-borosilil, engamelana nokuphendula kwamakhemikhali futhi ingamelana namazinga okushisa aphezulu adingekayo kwinqubo yokugaya i-COD. Ama-vials enzelwe ukubamba ivolumu ethile yesampula yamanzi kanye ne-reagents edingekayo ekuhlolweni kwe-COD.

ICOD (Chemical Oxygen 4. Isidingo sokugaya i-pushial ingilazi ekhethekile yelabhorethri esetshenziselwa ukunqunywa kwezidingo zomoya-mpilo wamakhemikhali kumasampula wamanzi. I-COD iyisilinganiso senani le-oksijini elidingekayo kumakhemikhali ama-oxidize arganic kanye nezinto ezingaphansi kwamandla akhona emanzini.
I-Cod yokugaya i-vial ngokuvamile iqukethe ingilazi noma ipulasitiki yepulasitiki nge-cap screw cap eqinile. I-Vial yenzelwe ukubekezelela amazinga okushisa aphezulu kanye nokusabela kwamakhemikhali okwenzeka phakathi kwenqubo yokugaya i-Cod.
