MilliporeSigma's water offerings are focused on providing fast, reliable and accurate testing capabilities through spectrophotometric analysis, including both bench top and handheld instruments as well as prepackaged chemistry to speed up analysis.
The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.
In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.
Currently the US EPA has not promulgated a single method for the analysis of Total Nitrogen (TN). Most states that have TN regulations require permitee's to measure TN as the composite of TKN, Nitrate and Nitrite. This approach is costly, time consuming, and susceptible to variability based on the methods used for the individual analytes. We are excited to announce the introduction of a Total Nitrogen Test Method consisting of a single spectrophotometric test kit. The method has been evaluated in a multilab study and this webinar will present the results of that study as well as an overview of the savings made possible by utilizing this new method for testing Total Nitrogen.

The quality of drinking water is regulated by a variety of guidelines, such as the EU Council Directive 98/831,2 and WHO guideline. The key principles used to define these limits consider both health hazards and sensory and technical reasons. Iron, for example, does not exhibit a risk for health in concentrations usually found in drinking water.
Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.
Utilities using ozone for disinfection must meet strict regulatory requirements for bromate. MilliporeSigma has been in the business of improving analytical equipment to make life in the lab more efficient and cost-effective for many years. Water Online spoke with MilliporeSigma about a new method for measuring bromate in drinking water.
Many industries use laboratory analyses to help with process control and regulatory compliance. However, process operators often need real-time results to make adjustments. Mobile testing methods are critical for troubleshooting problems and optimizing performance.
Many treatment facilities test for chemical oxygen demand on a regular basis. Some laboratory test methods can be time consuming and expose technicians to toxic chemicals. In addition, interference from components in the samples may affect the test results. MilliporeSigma is a global leader in the life science industry and has produced test kits to measure numerous analytes. Water Online spoke with MilliporeSigma about advances in measuring chemical oxygen demand
The primary reason for laboratory testing at a water or wastewater plant is to determine if the facilities are meeting regulatory limits. Both proper operation and accurate testing are of utmost importance to ensure compliance. However, regulators and operators must consider limitations of the test methodology, as they may affect analysis results. The last thing any plant manager wants is unwarranted problems as a result of faulty analysis.
Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
Today’s environmental laboratories are audited and accredited companies where quality control (QC) and quality assurance (QA) reign. Advanced technology is needed to measure parameters for regulatory compliance down to parts per billion. In a world of regulatory mandates, can test strips still be used for water analysis?
Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused. Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle is crucial. Whether in lakes, pipes, or bottles, we can accompany you with our range of instruments, test kits and applications for your water and wastewater needs.
Aside from having to deal with weather, mud, and the occasional slippery rock, there are key issues related to sample quality that can make testing water specimens from the field a bigger challenge than lab testing. That is why, when it comes to confidence and accuracy in onsite testing for nitrates, nitrites, phosphates, pH, and more, there’s nothing like using the right tools to do the job on the spot. Here is a quick checklist of trials, tribulations, and potential solutions for streamside sampling.
