UPW-Q700HXJ Automatic Anionic Surfactant Analyzer

Product Introduction
The UPW-Q700HXJ Automatic Anionic Surfactant Analyzer is designed to determine anionic surfactants in tap water, surface water, and wastewater. Based on the methylene blue spectrophotometric method, it automates sample preparation, reagent addition, extraction, phase separation, measurement, data processing, and cleaning.
Traditional manual testing involves labor-intensive pretreatment, considerable reagent consumption, and direct handling of extraction solvents such as chloroform. The UPW-Q700HXJ integrates these procedures into an automated system, reducing routine manual operations and limiting operator contact with extraction reagents.
With a built-in 7-inch touchscreen, automatic standard preparation, and batch-sampling capability, this analyzer is suitable for environmental monitoring laboratories, water quality testing facilities, and research institutions.

Performance Features
• Fully automated analysis: Automates reagent dispensing, extraction, back-extraction, separation, sample introduction, measurement, and cleaning.
• Enclosed extraction system: Helps reduce operator exposure to extraction solvents during routine testing.
• Standalone touchscreen control: The built-in 7-inch touchscreen and control system eliminate the need for a separate computer during routine operation.
• Integrated sample processing: Combines sample loading and pretreatment in one compact system.
• Automatic batch testing: Supports continuous analysis of multiple samples with automatic measurement and data storage.
• Automatic moisture removal: Uses an imported oil-water separation membrane to remove water and impurities from the extract.
• Precise reagent dispensing: Combines precision syringes with peristaltic pumps to improve dispensing accuracy and processing efficiency.
• Adjustable extraction ratio: Allows users to adjust the extraction ratio according to testing requirements.
• Automatic calibration preparation: Automatically prepares standards at different concentrations and generates calibration curves.
• Automatic result printing: Prints measurement results directly from the instrument.

Working Principle
The UPW-Q700HXJ uses the methylene blue spectrophotometric method for anionic surfactant determination, following the referenced GB 7494-87 method and GB/T 5750.4-2006 standard.
The analyzer automatically adds methylene blue reagent and an extraction solvent to the water sample. Anionic surfactants react with methylene blue to form a blue ion pair that can be extracted into the organic phase. After repeated extraction and back-extraction, the analyzer removes residual water, transfers the prepared extract into a spectrophotometer flow cell, and measures absorbance at 652 nm.
The instrument calculates the anionic surfactant concentration from the calibration curve prepared using standard solutions, with results expressed as LAS-equivalent concentration.
