Real-Time Conductivity Monitoring Estimates Chloride Levels In Minnesota Watershed By Using The Aqua TROLL 200
Monitoring deicing chemical levels can help researchers, city governments, and regulatory agencies understand runoff impacts on surface water, groundwater, and surrounding environments.
The Importance Of Measuring Total Organic Carbon
Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.
Organics Monitoring (TOC)
Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.
Application Note: Miami Conservancy District Uses Nitrate Screening As Conjunctive Management Tool
Tasked with monitoring a watershed covering nearly 4,000 square miles, almost 2,300 miles of rivers and streams, and a huge aquifer that provides drinking water for more than 1.2 million people, water quality monitoring specialists at the Miami Conservancy District (MCD) in Dayton, Ohio, have their hands full.

Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS
QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
The Ipswich and Parker Rivers watersheds lie only a short
distance north of Boston, MA. The first settlements in these
watersheds began in the early 1600s. Since that time, residents
have relied heavily on the natural resources of the Parker and
Ipswich Rivers, their coastal estuaries and Plum Island Sound,
which is known as the Great Marsh. This ecosystem has been
designated and protected by the Commonwealth of Massachusetts
as an Area of Critical Environmental Concern (ACEC).

Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution
The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.
Monitoring Nitrates In Drinking Water And Wastewater
Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system.
Analyzing Total Organic Carbon In Sea Water
The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.
