Description

Phosphate Standard CAS NO 14265-44-2 is a high-purity, certified reference material (CRM) used for the precise calibration and validation of analytical instruments and methods. This standard is critical for ensuring measurement accuracy, traceability, and regulatory compliance in quantitative phosphate analysis. It is an essential tool for quality control laboratories, environmental monitoring agencies, and research institutions that require reliable and verifiable data for phosphate content in water, soil, food, and pharmaceutical samples.

Application

This certified phosphate standard is indispensable in various analytical and quality assurance processes, including:

• Instrument Calibration: Primary use for calibrating spectrophotometers, ion chromatographs, and auto-analyzers in environmental and industrial labs.
• Method Validation & Verification: Establishing the accuracy, precision, and detection limits of analytical procedures for phosphate determination.
• Quality Control (QC) & Assurance (QA): Serving as a known reference in routine QC checks to monitor the performance of analytical systems and ensure result reliability.
• Proficiency Testing: Used as a benchmark sample in inter-laboratory comparison studies to assess and harmonize analytical competence.
• Environmental Monitoring: Quantifying phosphate levels in wastewater, surface water, and drinking water to comply with environmental regulations (e.g., EPA methods).
• Agricultural & Food Analysis: Measuring phosphate content in fertilizers, soil extracts, and food products for nutritional labeling and safety compliance.
• Pharmaceutical Testing: Assaying phosphate in drug substances, excipients, and finished products where phosphate is a critical component or impurity.

Quality Control

Our Phosphate Standard is manufactured and certified under a strict quality management system. Each batch is traceable to primary standards (e.g., NIST) and undergoes rigorous testing to ensure exact concentration, homogeneity, and stability. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the certified value, uncertainty, method of analysis, and expiration date to support ISO/IEC 17025 accreditation and global regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Store at a controlled room temperature (15-25°C). Do not freeze. Ensure the container is kept upright to prevent leakage.
