Join ABB and Tarmac / CRH for a 60-minute conversation about continuous emission monitoring systems (CEMS), reviewing their decade-long partnership, how it is evolving to meet changing cement industry needs, and what the future holds. Until recently, high quality CEMS products and responsive field service were what mattered most to plant operators. Nowadays, digital software solutions are helping to maximize hardware up-time and minimize on-site support. And new approaches to delivering...

This eLearning session will discuss the basics of Karl Fischer titration chemistry and the two types of titration, volumetric and coulometric. We will also discuss why one might be preferred over another and the reagents used for both volumetric and coulometric titrations. We will also cover method development and validation strategy. Finally we will provide some tips and tricks to help you be successful with your Karl Fischer titrations.  Participants will learn: An overview of the...

In this 8 minute interview with Dave Worton, science area leader in the Gas Metrology Group at the NPL, Stephen Harrison raises some questions and topics concerning the air quality we all live in. Listen now to get the answers to questions like;- What is the National Physical laboratory’s role in Environmental Science and Air Quality Monitoring? What is the role of the NPL in science and air quality? What chemical species do you deal with and focus on in your role? Do you dea...

Have you got 3 mins and want to know what the future of VOC and NO2 measurement for ambient airquality monitoring will look like? David R. Worton of NPL has a few insights to share. Gas chromatography is an established technique, but we need to wait for the results. There has been a lot of movement towards direct read instruments, online gas analysers, NO2, VOCs, a lot of application potential. What have you and the NPL been doing to evaluate these techniques?Is there a clear winner for...

Spend 5 mins with Dave Worton, science area leader in the Gas Metrology Group at the NPL and Stephen B Harrison and learn about Gas mixtures stability. The NPL make a lot of physical reference standards, gas calibration mixtures and cylinders, NO2, VOC. Stephen asked Dave from the NPL about the challenges of creating precise, accurate, traceable and stable calibration mixtures for these chemicals?   How do you prep a cylinder to ensure its dry? What complexities do you encounte...

Monitoring Nitrogen dioxide as a pollutant in our atmosphere, techniques and reference materials.

This interview with David R. Worton of NPL, conducted by Stephen B Harrison, covers two of the most fascinating applications of gas analysis. Measurement of isotopes to identify the sources of green house gases and finger printing of human breath for clinical diagnostics. Stephen is convinced that analytical science has a huge and positive role to play in medicine and environmental protection. In this short, 6 minute video, Stephen interviews Dave from the NPL asking the following questi...

Due to contaminants complexity and the low amount at which pollutants are usually present in environmental samples, their analytical determination can be particularly challenging. Conventional sample preparation methods make use of large solvent volumes and involve intensive sample manipulation that can lead to sample contamination or losses of analytes. Even modern extraction technologies are expensive and offer limited productivity. To overcome these disadvantages, Milestone developed a rap...

From source water to wastewater, this webcast will outline the importance of tracking carbon levels. The ability to obtain carbon data with an online or laboratory TOC analyzer is critical to understanding the effectiveness of a plant’s treatment process and identifying process impurities. SUEZ will share case studies that highlight how laboratory and online TOC analysis can be utilized to drive optimal performance.

The ability to accurately determine organic loading and organic removal efficiencies go beyond regulatory compliance requirements. By acquiring real-time organic data at upstream treatment steps, immense opportunities to optimize a WWTP’s performance exists. Using TOC data to monitor early treatment steps, empowers operators with the knowledge to make critical process decisions. Decisions that if not made in a timely matter, would lead to an inability to manage varying wastewater influent a...

Organic load is one of the most important parameters for discharge control of municipal and industrial wastewater. Permissible limits are guided through regulations and must be monitored accordingly. However, further opportunity to optimize plant performance exists by monitoring organic loading in upstream treatment processes. The use of on-line controls allows limit values to be adhered to, products to be saved, and plants to be protected against unforeseen events. Total Organic Carbon (T...
