The Hach Ammonia ISE Analysis Package includes the Hach Ammonia Electrode which measures ammonia gas or ammonium ions in aqueous solutions that have been converted to gas by the addition of a strong base. The electrode is a complete electrochemical cell consisting of a glass pH electrode and a reference electrode.

The gas-permeable membrane separates the sample from a thin layer of electrolyte that is pressed between the pH bulb and the membrane. At high pH, ammonium is converted to ammonia gas. The gas diffuses through the membrane and causes a pH change in the thin layer of electrolyte. The potential across the pH glass changes as a result of the pH change and the electrode measures the change in potential. The measured pH change is proportional to the ammonia concentration in the solution.

The ammonia electrode will measure ammonia gas or ammonium ion (converted to gas by strong base) in a variety of aqueous samples. Applications include water, wastewater, boiler feedwaters, fertilizers, biological samples, fish tanks, and more.

Digital Mayfly Data Logger Sensor Stations Monitoring Watersheds

For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed. “ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.

Solar and Wind-Powered, Algae Tracking Boat Trialed in Florida

Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat. "This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.

CICHAZ Biological Field Station Provides A Unique Educational and Research Experience in Mexico’s Huasteca Region

The story of the Centro de Investigaciones Científicas de las Huastecas "Aguazarca" (CICHAZ) Biological Field Station, a member of the Organization of Biological Field Stations ( OBFS ), starts with Dr. Gil Rosenthal, Professor of Biology and Chair of Ecology and Evolutionary Biology at Texas A & M University . Rosenthal has worked in the Huasteca region of Mexico since 1994 and for years kept his research equipment at a local ranch/hotel with the dream of one day having a field station where he could run experiments with collaborators and students. Since 2005, Rosenthal has been the Co-Director of the field station along with his wife, Dr.
