Estándares de electroquímica

Los estándares de electroquímica son materiales de referencia críticos utilizados para garantizar la precisión y consistencia de las mediciones electroquímicas en aplicaciones de investigación e industriales. Estos estándares incluyen una gama de soluciones y materiales, como soluciones tampón de pH, estándares de turbidez y estándares de conductividad, que son esenciales para calibrar instrumentos y validar métodos. Apoyan el mantenimiento de los electrodos, aseguran la correcta medición de la demanda química de oxígeno (DQO) y proporcionan estándares redox fiables para evaluar los potenciales de oxidación-reducción. Los ajustadores de fuerza iónica y las sales ácidas mejoran la precisión de los análisis electroquímicos, mientras que los estándares fisicoquímicos ayudan a mantener la consistencia en diversos entornos de prueba. El cuidado y la calibración adecuados utilizando estos estándares son vitales para un análisis electroquímico preciso, apoyando aplicaciones en el monitoreo ambiental, control de calidad e investigación científica. Al proporcionar puntos de referencia fiables, los estándares de electroquímica juegan un papel crucial en lograr resultados de alta calidad y reproducibles en estudios y aplicaciones electroquímicas.

  • Reagecon 0.5 NTU Turbiform™ Stabilised Formazin Turbidity Standard


    This standard is an aqueous suspension of a formazin type product that carries all of the advantages of formazin but eliminates its shortcomings. It is stable; safe; EPA approved and accurate. - Reagecon have developed a proprietary synthetic process that produces a family of products called Turbiform™. These products combine most of the positive attributes of the formazin and AMCO APEA-1 range of standards already available from Reagecon; whilst eliminating most of the shortcomings. Most importantly; this process does not interfere adversely with the status of formazin as the recognised primary standard. - Product exhibits a wide range of particle sizes; shapes and slopes (similar to formazin) mean diameter 3 µm with distribution of between 1 and 20 microns; which are similar to the particle size and distribution found in most sample types. - This product can be used to calibrate; control; validate or qualify; almost any make or model of Turbidity measuring instrument. - Traceable to NIST reference material 1690 and 1691 - Can be used to calibrate; control; validate or qualify almost any make or model of instrument

  • Reagecon 3.5M Potassium Chloride Electrode Filling Solution (Electrolyte) Saturated with AgCl


    Concentrated or saturated Potassium Chloride (KCl) is the optimal electrolyte and filling solution for potentiometric titrations, direct pH measurement, redox or ion measurement where silver/silver chloride or calomel reference electrodes are used. However, saturated KCl is only sparingly soluble below 20°C, so if measurements below this temperature are to be carried out 3.5M Potassium Chloride remains in solution down to 15°C. - A good electrolyte must fulfil a number of conditions. The equitransference of the cation/anion combination should be as close as possible to being equimobile, have constant chloride activity, be of high electrical conductance and be as non-chemically reactive as possible. Reagecon 3.5M Potassium Chloride Electrode Filling Solution is a high quality product that fulfils all of these criteria
