Answer:The specified photometric chemical oxygen demand measuring range is 0 to 150 mg/L COD.
Answer:The kit provides sufficient prefilled 15.4 mm cell-test materials for 25 COD determinations.
Answer:Yes. The COD reagents are strongly acidic and hazardous, and this formulation contains mercury requiring regulated disposal.
Merck Spectroquant COD Cell Test for Other Photometers measures chemical oxygen demand in suitable water samples using a photometric oxidation procedure. The specified working range is 0 to 150 mg/L COD, making this formulation appropriate for lower-range testing when sample conditions and method limitations are met. The test includes prefilled 15.4 mm round cells and sufficient materials for 25 determinations. It is designed for compatible photometers from other manufacturers that accept the cell size and provide the correct measurement program. Chemical oxygen demand testing involves strong oxidizing and acidic reagents; this kit also contains mercury and requires the corresponding hazardous-waste handling procedures. Treat every cell as a hazardous chemical container and follow appropriate PPE and sample digestion instructions. Verify whether a separate heating block, calibration or quality-control standard is required for the laboratory method. Check the suitability of sample chloride concentration and dilution before comparing results. Store the reagent kit at 15–25 °C and observe its shelf life. This test is not a direct biochemical oxygen demand measurement.
