Why Measure Ozone in Water? Ozone (O3) treatment has become an important tool for water quality engineers. As new more stringent requirements from regulators and customers must be met, ozone is often the oxidizer and disinfectant of choice for a wide range of process applications. Ozonation is used for viral, bacterial, and parasitic disinfection, the…
What Is a COD Test? A Chemical Oxygen Demand, or COD test, measures how much dissolved oxygen (DO) is consumed by the oxidation of organic matter and inorganic compounds such as ammonia or nitrite under controlled conditions. Researchers and industry professionals widely recognize COD as an indicator of wastewater influent and effluent quality. Analysts typically…
What Is a Comparator? A comparator is a set of sealed ampoules containing color standards made of dye mixtures. These mixtures closely match the color (hue) and intensity of CHEMetrics test ampoules when the tips are snapped in solutions of corresponding analyte concentrations. By sealing the dyes in ampoules, we can more closely recreate the…
Food and beverage packaging takes many shapes and forms in today’s marketplace. To maintain grocery shelf-life and flavor quality, sophisticated packaging equipment processes and assembles these products, having evolved away from traditional bottling and canning methods. Systems of quality control in the food and beverage industry have become more sophisticated as well as companies have…
