HCK Spectratest Sulphates

Precipitation of the Sulphate ion, with barium chloride, in an acid medium, so as to obtain a uniform barium Sulphate in terms of particle size, and consequently a homogeneous suspension.

- HYDROCHECK SPECTRATEST kits (which can be purchased directly) require the use of a photometer and allow for many precise analyses at a very low cost per analysis. HYDROCHECK MONOTEST kits are preferred because of their greater convenience and safety of use.
The cost per analysis of MONOTESTs is higher, but the analysis is simpler because the samples to be analyzed are introduced into optical glass tubes containing the predosed reagents that can be used directly in the appropriate photometers.
MONOTEST kits are especially recommended when there are few analyses to be performed. As for the photometer, it is preferable to use a spectrophotometer such as the Hydrocheck or Spectronic Genesys, since filter photometers give less reliable and accurate results, as well as always requiring the construction of a calibration curve.
