Product Introduction:

Total phosphorus (TP) is one of the important indicators of surface environmental water bodies. Excessive total phosphorus content can cause excessive proliferation of algae in surface water bodies, leading to eutrophication and damaging the aquatic ecological environment. This series of products refers to the national standard GB 11893 and is suitable for surface water and groundwater
Determination of total phosphorus in water, municipal sewage, and industrial wastewater.

Low range total phosphorus prefabricated tube reagentcharacteristic:

• ​Reliability - good reproducibility to ensure testing accuracy;

• Efficient - The testing process is simple and convenient, reducing time costs and improving work efficiency;

• Safety - Reduce exposure to hazardous chemicals and ensure personal safety of operators;

• Environmental Protection - Low reagent usage and minimal waste liquid generation;

• Flexible application - can directly replace mainstream brand reagents without the need to rebuild curves.

Low range total phosphorus prefabricated tube reagentOperation method:

1: Take out 2 TP prefabricated tubes, one of which is filled with 5.00mL of ultrapure water as the blank value, and the other is filled with 5.00mL of the water sample to be tested;

2: Add one packet of TP (LR) (I) reagent to each digestion tube that has been filled with blank and water samples;

3: Clean the outer wall of the tube with dust-free paper, hold the tube cover upside down and shake the solution in the prefabricated tube evenly；

4: Turn on the digestion device, heat to 150 ℃, set the time to 30 minutes, and place the two test tubes to be digested into the digestion chamber；

5：Place the pre fabricated tubes that have been digested in a test tube rack and cool them to room temperature；

6: Add a packet of TP (LR) (II) reagent to each pre cooled tube and shake；

​7：Add 1.00mL of TP (LR) (III) reagent and shake;

8: Place the shaken prefabricated tube in the test tube rack and let it stand for 2 minutes;

9: Clean the outer wall of the tube with dust-free paper (shaking and mixing the solution is prohibited at this time);

10：Put the processed blank prefabricated tube into the instrument to read zero; Place the processed sample tube into the instrument for reading.

Note:It can directly replace mainstream brand reagents without the need to reconstruct the curve.
