• The indophenol method, relatively modern, offers excellent sensitivity. The classic Nessler method, which is less sensitive, is preferred in the case of possible interference.
• The HYDROCHECK MONOTEST kits (which can be purchased directly) require the use of a photometer. Despite having a higher cost per analysis compared to SPECTRATESTs, HYDROCHECK MONOTEST kits are preferred because of their greater convenience and safety of use. The analysis with MONOTESTs is very simple because the samples to be analyzed are introduced into optical glass tubes containing the pre-dosed reagents that can be used directly in any photometer capable of accepting 16-mm diameter round tubes, such as Hydrocheck or Spectronic Genesys spectrophotometers. SPECTRATEST kits, which offer a significantly lower cost per analysis, are recommended when it is necessary to perform a number of analyses, to be repeated frequently. 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 precise results, as well as always requiring the construction of a calibration curve.
