Product Overview

Ozone Testing

Kit comes in a cardboard box and contains everything needed to perform 30 tests:  thirty ampoules, 25 mL sample cup, ampoule blank, and instructions. This kit requires the use of a SAM Photometer or a spectrophotometer capable of accepting a 13 mm diameter round cell and with a “Z dimension” of 15 mm or less.

The CHEMetrics Ozone (indigo) Vacu-vials Kit employs an innovative “self-zeroing” feature to eliminate the need to generate a reagent blank. Each Vacu-vials ampoule is measured before and after being snapped in sample. The change in color intensity, measured in absorbance, between reagent in the unsnapped and snapped ampoule is used to determine the ozone concentration of the sample.

Indigo Method
  • References: Bader H. and J. Hoigné, “Determination of Ozone in Water by the Indigo Method,” Water Research Vol. 15, pp. 449-456, 1981. APHA Standard Methods, 23rd ed., Method 4500-03B-1997
  • With the indigo method, indigo trisulfonate dye immediately reacts with ozone. The color of the blue dye decreases in intensity in proportion to the amount of ozone present in the sample. The test reagent is formulated with malonic acid to prevent interference from up to at least 10 ppm chlorine. Results are expressed as ppm (mg/L) O3.

Product Performance 
 

The precision data below is based on replicate analysis of ozone standards prepared in deionized water. Standards were analyzed on a spectrophotometer or CHEMetrics Single Analyte Photometer (I-2022 SAM) during ideal testing conditions. The 95% confidence interval of the distribution was determined from the standard deviation
