HI93723‑03 Chromium VI High Range reagents deliver fast, reliable hexavalent chromium (Cr⁶⁺) colorimetric analysis for Hanna photometers, using pre‑measured, high‑purity chemistry to ensure consistent accuracy in every test. Each packet is traceable and ready to use, making routine Cr⁶⁺ monitoring simple, repeatable, and lab‑quality in any environment. • Pre‑measured, high‑purity reagents for precise Cr⁶⁺ colorimetric testing • Compatible with Hanna benchtop and portable photometers • Individually marked packets for full lot and expiration traceability
These HI93723-03 reagents provide a fast, dependable way to perform colorimetric chromium VI analysis using compatible Hanna photometers. Each packet contains precisely measured, high‑purity chemistry based on an adaptation of the diphenylcarbohydrazide method, producing a distinct purple coloration when chromium VI is present. Once the reagent is added, the photometer interprets the developed color to deliver results in µg/L (ppb) of chromium VI. This reagent set is formulated for samples expected to fall within the 0 to 1000 µg/L measurement range.
