Description

Calmagite Triethanolammonium is a high-purity, water-soluble complex primarily used as a metallochromic indicator. This compound is valued for its selective chelating properties, enabling precise endpoint detection in complexometric titrations. It is an essential analytical reagent for industries requiring accurate metal ion quantification, such as water treatment, pharmaceuticals, and industrial chemical manufacturing.

Application

• Complexometric Titration Indicator: Primary use as a visual endpoint indicator for the titration of calcium and magnesium ions with EDTA.
• Water Hardness Analysis: Critical for testing calcium and magnesium concentrations in industrial process water, boiler feed water, and municipal water supplies.
• Pharmaceutical Quality Control: Used in the assay of raw materials and finished products where calcium or magnesium content must be precisely controlled.
• Food & Beverage Testing: Employed in the analysis of mineral content in dairy products, fortified foods, and beverages.
• Research & Development: Serves as a key reagent in analytical chemistry research and method development for metal ion detection.
• Industrial Process Monitoring: Applied in continuous or batch monitoring of metal ions in chemical manufacturing and plating bath solutions.

Quality Control

Our Calmagite Triethanolammonium is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including identification (IR), purity assay (HPLC/Titration), and loss on drying, to ensure it meets precise performance criteria for use as an analytical indicator. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to protect from moisture absorption and contamination.
