15mL cod vials with low range on stock

For best results, use the low range and ultra-low range test for samples with high chloride concentrations (approaching maximum concentration) and low COD concentrations. If sample dilution will cause the COD concentration to be too low for accurate determination, add 0.50 g of mercuric sulfate (HgSO. 4) to each COD vial before the sample is added.

Oct 14, 2010 · Pre-prepared low-range (3-50 ppm) or high-range (20-1500 ppm) vials are selected for the COD test based on expected results. Both ranges can be used if expected results are unknown. One vial is marked as a “blank,” and three or four vials are marked with known standard levels.

Chemical oxygen demand is an aggregate property of water, and no CAS Registry Number is appropriate. 1.2 The method consists of two procedures: the first (“Low Range”) is applicable to natural and treated waters at concentrations from 15 to 150 mg/L COD; and the second (“Mid-Range”) is applicable from 100 to1500 mg/L COD .

COD concentration increases. The low range COD digestion is read at 420 nm and is proportional to the decrease in the dichromate ion (Cr 2 O 7 2-), which causes the solution to move towards a colorless/pale blue shade as the COD concentration increases. Your digested zero COD standard will have a higher absorbance than your digested 100 mg/L
