Reagecon's Zinc Sulphate 0.1M (0.1N) Analytical Volumetric Solution (AVL) is tested by an ISO 17025 Accredited Test Method (A2LA Ref: 6739.03). This product is a fully factorised; high purity; stable product; developed and tested for oxidation/reduction titrations. This Analytical Volumetric Solution; also called titrant; standard titrant or standard solution; is tested to a specification of ± 0.1%. It is a reagent of known concentration; that is dispensed from a burette or other dispensing apparatus to a sample (analyte); until a reaction between the two liquids is judged to be complete. The product may be used for manual titrations; or more commonly automatic titrations; to determine the end points by detection of any of several properties. Oxidation/reduction titrations depend on changes in the electropotential of the oxidation reduction system and always involves a reaction between an oxidising and reducing pair. - Titration is a rapid, economical and versatile analytical tool. This Reagecon titrant is accurate, stable, reproducible and fully factorised. Titrations performed with this product, exhibit defined stoichiometry, are quantitative, establish an equilibrium that is definitive and fast and provide unambiguous results. Stability is proven (either opened or unopened) for the shelf life of this product.

Reagecon’s Multi Element Standard for ICP; ICP-MS in 2% HNO₃ is manufactured from ultra-pure metals or salts. This product is manufactured gravimetrically using the mass balance approach: 100% less the sum of all impurities (w/w). Prior to bottling; the final product is tested and verified using ICP-MS and is reported using the gravimetric result; corrected for density. The results are reported in mg/kg and mg/L on the basis of weight and density. Reagecon hold ISO 17025 accreditation (A2LA Ref: 6739.02) for calibration of laboratory balances. - GHS/OSHA compliant, REACH - This product is produced in a highly controlled cleanroom (ISO 7) environment, using ultra-pure water (specially treated for the production of mass spectroscopy standards), triple distilled acids and triple leached pre-cleaned bottles. The titrimetry and spectroscopy are controlled and calibrated using separate standards, so the product comes with two layers of traceability including NIST Standards, where available. All of the uncertainties of measurement for this product are calculated according to Eurachem/CITAC guidelines and reported as expanded uncertainties at the 95% confidence level. Description | Concentration: - Cobalt (Co): 3 µg/mL (ppm). - Vanadium (V): 1 µg/mL (ppm). - Nickel (Ni): 5 µg/mL (ppm).
