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.
Application Note: Building A Baseline In Florida
The Florida Department of Environmental Protection (DEP) knows that establishing dissolved oxygen (DO) and nutrient criteria for the state’s water bodies is a challenge – both scientifically and politically
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.
How One Wastewater Treatment Plant Saved Time And Money Measuring Turbidity And TSS
The wastewater treatment plant of a major corporation is designed for a population capacity of 6 million people and is considered a very large wastewater treatment plant.
Application Note: Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography
This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC. By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA
Underground Treatment Of Airport Deicing Fluid
While keeping air flight safe, airports and airlines are also obliged to clean up after themselves and protect nearby streams and water bodies. And due to increasing chemical usage and looming regulations, some airports will need to invest in significant infrastructure upgrades to capture and treat stormwater contaminated with deicing fluid.

2 Applications That Triggered The Rise Of Coriolis Flow Measurement
Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.
Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
Total Kjeldahl Nitrogen: Simplified With s-TKN™
The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance. By Andrew Antonio, Municipal Wastewater Market Manager and Derek Walker, Applications Development Manager
Precipitant Savings Through Optimized Phosphate Elimination With Integrated Predictive Diagnostics
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
