Overview
The LEICI Total Phosphorus Working Reagent Pack (Model: 780300N02) is a dedicated Reagent Pack for water quality testing, suitable for measurement of total phosphorus concentrations in the range of 0.000 to 1.000mg/L. The Reagent Pack is designed for use with LEICI DGB-401 and DGB-428 instruments to provide accurate total phosphorus analysis.
Features
1. Provide accurate total phosphorus concentration measurement, covering the range of 0.000 to 1.000mg/L.
2. Contains a variety of Reagents: 1 100mL plastic bottle of molybdate solution, 25 packs of ascorbic acid powder, and 25 packs of potassium persulfate powder.
3. Optimized for LEICI DGB-401 and DGB-428 instruments to ensure compatibility and Reliability.
Principle
The Total Phosphorus Working Reagent Package works based on the principles of chemical digestion and Colorimetry. First, potassium persulfate is used for digestion treatment to convert the phosphorus in the water sample into positive phosphoric acid salt; then the blue complex is formed by the reaction of ascorbic acid reduction and molybdate. Color intensity is proportional to the total phosphorus concentration, which can be quantified by instrument measurement Absorbance.
Applications
Water quality testing, environment monitoring, laboratory analysis
Steps
Prepare water samples and instruments to ensure that DGB-401 or DGB-428 instruments are calibrated.
2. Take an appropriate amount of water sample and add potassium persulfate powder for digestion.
3. Add ascorbic acid powder and molybdate solution and mix well.
4. Place the mixture in the instrument and follow the instructions for measurement.
5. Read and record the total phosphorus concentration results.
Notice
• Please read the product manual and instrument operation guide carefully before use.
• Reagents should be stored under specified conditions, away from direct sunlight and high temperatures.
• Wear appropriate protective equipment such as gloves and goggles when operating.
• Ensure that the water sample and Reagent are free of contamination, so as not to affect the measurement accuracy.
• Reagents and samples must be handled according to environmental regulations.
