Answer:It is used for the Spectroquant 500–10,000 mg/L COD test range.
Answer:No. The test procedure requires COD Solution B together with the corresponding COD Solution A.
Answer:The designated volume is 1.80 mL of Solution B per determination.
Spectroquant COD Solution B is the companion liquid reagent for the 500–10,000 mg/L chemical oxygen demand photometric test range. It is used with Spectroquant COD Solution A rather than as a standalone COD measurement solution. Each determination requires 1.80 mL of Solution B in conjunction with the specified amount of Solution A and the established sample preparation and digestion procedure. The 495 mL bottle is intended for controlled laboratory COD testing in matrices such as industrial wastewater, process waters and other samples with substantial oxidizable organic content. The liquid is strongly acidic, so technicians must use appropriate protective measures and handle any reaction residues as regulated laboratory waste. Keep the two reagent containers clearly identified to prevent dispensing errors. Consistent volumetric technique, digestion conditions and photometer calibration are important for obtaining comparable results across batches. If the anticipated COD concentration falls outside the method range, select an appropriate alternative range or validated sample dilution before measurement.
