Reagecon's Bromate Standard for Ion Chromatography (IC) 1mg/mL (1000ppm) in H₂O is manufactured from ultra-pure material. This product is manufactured gravimetrically. Prior to bottling, the final product is tested and verified using a state of the art ion chromatograph and it is certified using the gravimetric result, corrected for density, to a specification of ± 0.2%. The certified results are reported and certified in mg/kg and mg/L on the basis of weight and density. Reagecon holds ISO/IEC 17025 accreditation for calibration of laboratory balances (INAB Ref: 265C). All of the measurement and gravimetric functions are carried out under a highly regulated temperature regime. Reagecon holds ISO/IEC 17025 for Temperature Calibration in the range of -196 to +1200°C (INAB Ref: 265C) and ISO/IEC 17025 accreditation for density measurement using Oscillating U-Tube and Bingham Pycnometry Methods (INAB Ref: 264T).
