Description

Nitrite-Nitrate Chloride Cal is a high-purity chemical standard used for the calibration and validation of analytical instruments. This compound is critical for ensuring accurate and reliable measurement of nitrite, nitrate, and chloride ions in complex matrices. It is an essential reagent for quality control laboratories in the environmental monitoring, water treatment, food & beverage, and pharmaceutical industries where precise ion analysis is mandatory for regulatory compliance and product safety.

Application

• Primary Standard for Ion Chromatography (IC): Calibration and quality control of IC systems for anion analysis.
• Environmental Water Testing: Standard reference material for analyzing nitrite, nitrate, and chloride levels in drinking water, wastewater, and surface water.
• Food & Beverage Safety Analysis: Used to validate methods for detecting and quantifying preservatives (nitrites/nitrates) and chloride in processed foods and beverages.
• Pharmaceutical QC: Serves as a system suitability standard in pharmacopeial methods for impurity testing and ion analysis.
• Agricultural & Fertilizer Analysis: Calibration standard for testing soil and fertilizer samples for key nutrient and contaminant ions.
• Industrial Process Control: Monitoring anion levels in industrial process streams, cooling water, and boiler feed water.

Quality Control

Our Nitrite-Nitrate Chloride Cal is manufactured under strict quality management systems. Each batch is analyzed to ensure precise concentration, stability, and traceability to NIST standards where applicable. We provide comprehensive Certificates of Analysis (COA) detailing assay, purity, and verification data. Our quality commitment supports compliance with relevant pharmacopeial (USP, EP) and environmental (EPA, ASTM) method requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect concentration and stability.
