HPS Nitrate Anion IC Standard – 1,000 µg/mL in Water
The HPS Nitrate Anion IC Standard is a high-quality, single-component reference standard designed for the accurate determination of nitrate by ion chromatography (IC). Prepared from high-purity sodium nitrate in a water matrix, it provides laboratories with a reliable calibration solution for routine analysis, quality control and method validation.
Traceable to NIST SRM 3185, this nitrate standard supports consistent and defensible analytical results in environmental, industrial and regulatory laboratories. It is suitable for use with EPA Method 9056 and other ion chromatography methods used to determine inorganic anions in water and related samples.
Reliable Nitrate Calibration for Ion Chromatography
Accurate calibration is essential for dependable nitrate measurement. The HPS Nitrate Anion IC Standard provides a known concentration of nitrate in a high-purity water matrix, making it suitable for preparing calibration solutions, verifying instrument performance and carrying out routine quality-control checks.
The standard is manufactured under ISO-accredited quality systems and offers an 18-month shelf life, supporting laboratories that require traceable reference materials and consistent analytical performance.
