HCK Spectratest Phosphates (High)

Measurement of the color intensity of the yellow compound formed by reaction of ammonium molybdate with orthophosphates in the presence of vanadium.

5 – 100 ppm PO4

200

Purified, waste and thermal circuits

• 1 bottle of 35 ml of reagent A
• 2 bottles of 35 ml of reagent B
• 2 plastic test tubes of 20 ml with stopper
• 2 test tubes of 16 mm optical glass with stopper
• 1 syringe of 5 ml
• Instructions (English)

- The method detects phosphorus present in the form of orthophosphate. Organic phosphonates can be measured using the HCK TITRATEST PHOSPHONATE, and total phosphorus using the HCK MONOTEST TOTAL PHOSPHORUS kits.
- HYDROCHECK SPECTRATEST kits (which can be purchased directly) require the use of a photometer, such as the HC6000, in order to perform many precise analyses at a very low cost per analysis. HYDROCHECK MONOTEST kits are preferred for their greater convenience and safety of use. The cost per analysis of the MONOTEST kits is higher, but the analysis is simpler, since the samples to be analyzed are placed in optical glass tubes containing the pre-dosed reagents and can be used directly in suitable photometers. MONOTEST kits are especially recommended when there are only a few analyses to be performed. As far as the photometer is concerned, it is preferable to use a spectrophotometer such as the Hydrocheck or Spectronic Genesys, as filter photometers give less reliable and accurate results and always require the construction of a calibration curve.
