TDS standard solution 900 ppm

TDS Standard Solution 900 ppm is a pharmacopeial-grade reference solution designed for use in pharmaceutical quality control, laboratory calibration, and analytical testing for the calibration and performance verification of total dissolved solids (TDS) meters, conductivity meters, and water quality monitoring instruments.

🏭⚗️ Production
Prepared under strictly controlled GMP- and pharmacopeial-compliant conditions to ensure precise TDS concentration, chemical stability, and minimal contamination. The 900 ppm TDS value is achieved using high-purity salts dissolved in deionized water, providing a uniform ionic composition representative of standard TDS solutions. The solution is supplied in chemically resistant, sealed, and light-protected containers to prevent evaporation, contamination, or degradation. Each batch is validated according to USP <645>, EP 2.2.38, and relevant pharmaceutical testing standards to ensure accuracy, uniformity, and reproducibility.

🔬 Properties
A clear, colorless aqueous solution with a defined TDS of 900 ppm. Exhibits excellent stability under recommended storage conditions. Minor variations in TDS may occur after prolonged storage or exposure to extreme temperatures; gentle mixing restores homogeneity without affecting the reference value.

🧪 Applications
Used in pharmaceutical, analytical, and educational laboratories for calibration, validation, and performance testing of TDS meters, conductivity meters, and other water quality instruments. Suitable for method validation, routine QC analysis, equipment qualification (IQ/OQ/PQ), and compliance with pharmacopeial standards requiring mid-range TDS references. Ideal for ensuring accurate measurements in water quality testing, formulation development, process control, and laboratory research.

⚠️ Safety
Considered low-hazard but should be handled according to standard laboratory safety practices. Avoid ingestion, inhalation, and direct contact with skin and eyes. Use appropriate personal protective equipment, including gloves, goggles, and a lab coat. Store in tightly sealed, light-protected containers in a cool, dry environment. Dispose of according to pharmaceutical laboratory waste regulations and environmental safety guidelines.
