In high-precision industrial fields such as chemical, pharmaceutical, food, and energy, moisture content is a key parameter that determines product quality, stability, and safety. The volumetric titration Karl Fischer moisture analyzer, based on its precise measurement principle based on Karl Fischer reaction, has become an indispensable moisture analysis equipment in laboratories and production lines worldwide. This article will analyze the core value of this instrument from the dimensions of technical principles, core advantages, application scenarios, and operating standards.
Core advantages: precision, efficiency, and adaptability
Full range coverage and high precision
The volumetric method can cover a wide range from ultra-low content (such as ppm level moisture in transformer oil) to high content (such as moisture in solid samples) by adjusting the reagent concentration and titration volume.
Automation and intelligent operation
Modern instruments integrate a 7-inch color touch screen, a fully automatic titration system, and data storage functions (such as storing 2000 sets of results). Users only need to set parameters and inject samples, and the instrument can automatically complete titration, calculation, and result storage.
Anti interference design and environmental adaptability
For complex samples, the instrument is equipped with liquid resistance compensation function, which can automatically adjust electrode sensitivity to adapt to different solvents; Using corrosion-resistant PTFE materials (such as reagent bottle caps and drying tubes) and UV resistant shields to ensure stable operation at ambient temperatures of 5-40 ℃ and humidity ≤ 80%.
Application scenario: Moisture control in multiple industries
Food and Agricultural Products
The moisture content of dry foods such as biscuits and milk powder directly affects their shelf life and the risk of microbial growth.
Petrochemical and Electric Power
Trace amounts of moisture in transformer oil and lubricating oil can reduce insulation performance and cause equipment failure. The measurement accuracy of Karl Fischer titration moisture analyzer (volumetric titration method) meets the requirements of JJG 1154-2018 "Calibration Regulations for Karl Fischer titration moisture analyzer".
Pharmaceutical and Biotechnology
The moisture content of pharmaceutical raw materials and intermediates must comply with the requirements of the Chinese Pharmacopoeia. The volumetric instrument can detect the moisture in active ingredients and excipients, avoiding degradation or clumping caused by moisture.
