Hach Phosphorus (Reactive and Total) TNTplus Vial Test
For determination of Reactive (ortho) and Total Phosphorus (phosphate) in wastewater, drinking water, boiler water, surface water and process water.
- Easy and safe handling
- No reagent blank necessary
- Automatic method detection
Phosphorus TNTplus chemistry and your Hach spectrophotometer are engineered to simplify water analysis for accurate results, every time.
For determination of Reactive (ortho) and Total Phosphorus (phosphate) in wastewater, drinking water, boiler water, surface water and process water. TNTplus phosphorus reagents can provide an Orthophosphate or Total Phosphorus result.
Ascorbic Acid Method is Equivalent to EPA 365.1.
Phosphorus TNTplus chemistry allows you to test for reactive or total phosphorus with each vial. Follow the easy to navigate procedure printed on the lid of the box and then insert the TNTplus vial into your Hach spectrophotometer for an immediate result. Measurments are reported in the low range of 0.15 - 4.50 mg/L as PO4. If you are required to digest your phosphorus sample, performing this step in the sealed vial eliminates loss to evaporation and allows up to 30 simultaneous digestions depending on which DRB200 Reactor Block you are using.
Phosphates present in organic and condensed inorganic forms (meta-, pyro- or other polyphosphates) are first converted to reactive orthophosphate in the total phosphorus procedure. Treatment of the sample with acid and heat provides the conditions for hydrolysis of the condensed inorganic forms. Organic phosphates are also converted to orthophosphates in the total phosphorus procedure by heating with acid and persulfate. The reactive phosphorus procedure measures only the reactive (ortho) phosphorus present in the sample.

The value of multi-lake studies is well understood by international organizations like the Global Lake Ecological Observatory Network (GLEON) and the scientists who work tirelessly to provide data to the larger network. Rebecca North, an associate professor at the University of Missouri-Columbia , is one of many researchers involved in multi-lake research initiatives and conducting research locally in her home state.
Having been born and raised on the shore of Lake Ontario, North grew up in a community that revolved around water. She also saw firsthand one of the worst water quality bodies of the world, the Bay of Quinte, decline throughout her lifetime.Read More
It is no secret that in today's world, most scientists do not stick exclusively to science–they must be educators, communicators, and advocates. The looming threats facing the planet's climate and the growing distrust in science by the public have forced scientists to expand and improve their capacity for science communication to the world.
From repeatedly testifying before the U.S. Congress to winning an Emmy as the Chief Scientific Advisor for an award-winning nature documentary, marine ecologist James W. Porter has been thrust into the public eye.Read More
Historically, water quality monitoring during the winter has been difficult and often avoided altogether—however, monitoring throughout the year can highlight the influence of various environmental stressors and track the changes systems undergo during the winter. In particular, long-term monitoring efforts in systems like Mohonk Lake can underline the effects of climate change and acid rain.
David Richardson, a professor of biology at the State University of New York (SUNY) at New Paltz , spends his time outside of the classroom monitoring the nearby watersheds. After getting his engineering undergraduate degree, Richardson realized he wasn't interested in the typical job offerings and applied to an ecological science graduate program at the University of Maryland.Read More
