The detection steps and precautions of total phosphorus detector

by:BOQU     2022-01-07

Total Phosphorus Detector is a fast G-terminal total phosphorus analyzer. The detector has an intelligent operation. J quasi-chemical detection, which can expand and upgrade the measurement of multiple parameters. It can be widely used in environmental monitoring stations of the Environmental Protection Agency, sewage treatment plants, universities and scientific research institutes, pharmaceuticals, papermaking, chemicals, printing and dyeing, textiles, leather, brewing, dairy, electroplating, municipal engineering, and other industries.

Detection steps of total phosphorus detector:

1. Standard curve drawing

a. Digestion: Prepare phosphate standard solutions of different concentrations in accordance with relevant requirements, add the corresponding digestion solution, and complete the digestion under the specified digestion conditions.
b. Color development: Add corresponding reagents to develop color.
c. Curve drawing: Measure the absorbance of each standard solution and draw the standard curve of total phosphorus. The special total phosphorus testing equipment has a built-in standard curve when it leaves the factory, so there is no need to make it yourself.

2. Sample testing:
a. Digestion: Take a certain amount of water sample as required, add the corresponding digestion solution, and complete the digestion under the specified digestion conditions.
b. Color development: Add corresponding reagents to develop color.
c. Detection: Use pure water as a reference to measure the absorbance of the sample, and find out the content of total phosphorus on the total phosphorus standard curve. The dedicated total phosphorus detection equipment will directly display the total phosphorus detection result after pressing the detection button, without conversion.

Precautions for testing:

1. All glassware used for testing should be soaked in dilute hydrochloric acid or dilute nitric acid, and washed with pure water before use.

2. Because phosphate is easily adsorbed on the plastic surface, avoid using plastic bottles for water samples with less phosphorus.

Functional characteristics of total phosphorus detector:

1. J Quasi-determination: Using chemometric statistics, intelligent analysis and statistics of multiple sets of data, effective;

2. Simple operation: 8-inch color large screen, guided operating system, humanized interface, easy to understand after booting;

3. Storage and printing: 20000 groups of data storage, one-key printing of experimental data;

4. Light source performance: imported LED cold light source, with a good optical performance and strong stability;

5. Data protection: The host has a built-in lithium battery, and data will not be lost in the face of sudden power failure;

6. Rugged quality: The casing adopts mature ABS engineering plastic technology, the instrument is beautiful and corrosion-resistant;

7. Prefabricated reagents: standard prefabricated reagents, safe and fast, no need for the user to prepare;

8. A complete set of experimental supplies are provided, ready for use out of the box;

9. Safe digestion: equipped with 16-hole multifunctional intelligent digestion instrument, built-in alarm reminder.
