  • Can I measure monochloramine on a palintest photometer?

    Normally, DPD 1 gives free chlorine Addition of DPD 3 (excess KI) gives free and combined chlorine (chloramine) Instead of DPD 3, DPD 2 is used (which has a trace of KI).  This only reacts with monochloramine.  So subtracting the DPD 1 result gives the level of monochloramine.  DPD 2 part code is 1177203 priced the ...

  • Chemical analysis of drinking water from some communities in the Brong Ahafo region

    This study consisted of the determination of the trace metals and some physiochemical properties in drinking water samples from the Brong Ahafo region of the Republic of Ghana, where drinking water samples are not treated before it is consumed. The purpose was to ascertain the quality of water from these sources. Samples were taken from fifteen sampling points and analyzed for the following ...

  • ITS marketing manager quoted in WaterTech

    Professional, ethical testing will start you off on the right foot and will directly determine which services the customer may need. Many substances could be in a customer’s water, but, “It’s not necessary to test for every parameter; that’s what labs are for,” advises Rob Samborn, director of sales and marketing for HM Digital, a Los Angeles-based maker of water ...

  • Chlorine mystery solved

    Following the installation of in-pipe drinking water quality monitoring sondes, distribution engineers discovered an occasional significant disparity between the Intellisondes’ data and results from grab samples tested by a photometer tablet (DPD) method. For most of the time, there was close agreement between the two methods, but periodically, the photometer results varied wildly, whilst ...
