The Hach pH Platinum Series Flat-End Electrode, features improved reference junction designs, provide fast, stable response and accurate measurements. Conventional combination electrodes use porous
frits as the junction between the reference half-cell and the sample. The porous material rapidly clogs with precipitated silver chloride, causing unstable junction potentials. The Flat-End pH Electrode uses a double junction reference half-cell with a free-flowing outer reference junction. The free-flowing junction provides nearly constant junction potential, greater accuracy and reliability than conventional porous junction electrodes, and is ideal for both routine and demanding applications.

The Flat-End pH Electrode contains a silver/silver chloride element in an inner chamber that contacts the electrolyte solution at an inner junction. Electrolyte flows from the free-flowing outer
junction at the electrode tip. This design makes it ideal for use with samples containing sulfide or other substances.

This Hach electrode uses a flat glass membrane that can be used at temperatures of 0 to 45 C, hydrates easily, and has durability at high temperatures. A moderate sodium error occurs at pH levels greater than 12.

Ocean acidification: University of Washington's giant plastic bags help control research conditions

With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

NOAA Alaska buoy network to monitor North Pacific ocean acidification

National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action. “We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks. To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.

Watchful Eyes on One of Maine's Crown Jewels: Jordan Pond

Formed by a glacier, Jordan Pond is among Maine's clearest, most beautiful bodies of water. It's also a critical freshwater resource, and watchful eyes are protecting it. EM spoke with Dr. Rachel Fowler, Friends of Acadia's aquatic scientist, about her work monitoring Jordan Pond. A postdoctoral research scientist at the University of Maine, she is a member of a partnership among the National Park Service, the University of Maine Climate Change Institute, and Friends of Acadia that began deploying the Jordan Pond buoy in 2013. Canon provided the initial support for the project. Friends of Acadia is a nonprofit organization that supports different projects in the park.
