HI96788-25 Phenols Pre-dosed Reagent Set 13 mm Vial HI96788-25 is a kit of pre-dosed reagents in vials for the determination of Phenols. There are vials for 25 tests to be used with Hanna’s HI801 and HI802 spectrophotometers. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with lot number and expiration date for traceability. The method used is Adaptation of 4-aminoantipyrine method, which complies with ISO 6439 and EPA 420.1. The procedure involves the addition of a very representative sample volume (5 mL) and the use of 13 mm (internal diameter) cuvettes, with a longer optical path than many other vials on the market. This ensures accurate absorbance measurements and greater repeatability of results. The kit allows to obtain very accurate results, even at low values (below 0.10 ppm), and thanks to the zeroing of the sample it is possible to eliminate color and turbidity interferences. HI96788-25 can be stored at room temperature, avoiding the inconvenience of having to store them in the refrigerator. In addition, the reagents have a four-years shelf life. Signicance and Use Phenol analysis is critical in water quality assessment due to its toxicity and persistence in the environment. Present in industrial eÇuents, pesticides, and natural decomposition processes, phenols can signicantly impact aquatic ecosystems and human health. Regular monitoring ensures compliance with stringent environmental regulations, aids in evaluating treatment e´cacy, and supports the protection of water resources. Accurate phenol measurement is essential for industrial discharge control, environmental preservation, and safeguarding public health.
