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...

Make the right decisions faster during your disinfection control and hygiene monitoring processes for food & beverage manufacturing. Hygiene monitoring, in-process testing and disinfection control – regardless of what you call this step it remains critical in ensuring the safety of your product. Join our webinar to learn the importance of Disinfection control of your production sites. Attention to hygiene during the manufacture of food and beverage products is paramount due to the eve...

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...

Having the support of a data management solution with intrinsic flexibility enables laboratories across all industries to increase productivity and efficiency. As the largest refiner in the U.S., Marathon Petroleum Corporation (MPC) needed a LIMS capable of centralizing the laboratory operations of multiple locations over three North American time zones.  At the same time, they needed a system that could meet the unique configuration needs of each site without sacrificing upgradability.  In...

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.
