An yi ƙididdigar spectrophotometry a tsawon raƙuman ruwa na 540nm. Pre-magani na samfurin ruwa: narke samfurin ruwa a babban zafin jiki tare da permanganate, a sanyaya bayan kara karewa, a titrate da reducer zuwa bayani launi. An auna samfurin ruwa da aka riga an sarrafa ta hanyar da aka ambata a sama, wato, jimlar chromium.
