  • This application note demonstrates the suitability of ultrapure water produced by a Milli-Q IQ  7000 water purification system for the IC analyses of inorganic ions and DBPs in drinking water.

  • This application note demonstrates the extraction and subsequent analysis of 25 related analytes from water using Supelco SPE cartridges.

  • The Ascentis Express PFAS HPLC column is designed for the separation of novel and legacy PFAS as per recent EPA methods. A specific PFAS delay column prevents background PFAS contamination from interfering with sample results in quantitative LC-MS methods.

  • In response to environmental testing demands for faster LC-MS analyses, the new Ascentis® Express PFAS HPLC and delay columns allow the highly efficient separation of 33 PFAS compounds in 5 minutes with reduced background contamination.

  • 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.

  • Wastewater is a focal point for public health professionals evaluating levels of COVID-19 community infection. Here are some considerations on the use of membranes for efficient SARS-CoV-2 virus water sample preparation.

  • Here is a look at how synthetic carbon technology makes it easier to design a better filtration medium tailored to the most challenging process demands.

  • Laboratory performance is critical for evaluating water treatment operations — from operational and disinfection efficiency to regulatory compliance reporting to human health and safety. Errors, oversights, or incomplete documentation can plague even the most finely tuned water treatment utilities. Here is a quick review of tools and techniques that can improve workflow accountability.

  • A quality outcome is only as reliable as the components and processes used to create and test it. When it comes to municipal drinking water, food, beverages, wastewater effluent, and other industrial applications, having reliable microbiological testing reference materials to benchmark quality control (QC) processes is essential. Here are some important points to consider when establishing or managing QC programs.

  • Going through the motions of water sample testing for regulatory reporting requirements is only half the battle. It is also important that water operators use appropriately qualified reference materials and procedures to ensure the accuracy and reliability of their results. Here are some insights into reference-material evaluation that can generate the highest confidence in water testing results.

  • It’s common to see “BPA Free” labels on water bottles and other containers, a response to consumers who have grown increasingly wary of the contaminant. However, testing for BPAs that may have found their way into drinking water sources has traditionally been cumbersome and expensive, so municipalities could be exposing their customers to unsafe levels. The good news is that newer advancements are making it easier to use existing technologies to monitor for the pollutant.

  • Proficiency Testing (PT) is the name used by the International Standards Organization for a procedure also known as “inter-laboratory study” or “external quality assessment” or “ring test”. Proficiency testing, in simple terms, comprises a sample sent to a group of laboratories for measurement. The labs know what might be in the sample, but they don’t know exactly what is there or the concentration. Their results are compared with the known or true value and the lab is assigned a “Z” score to show how closely their result came to the target.

  • Traditionally when it comes to analysis, there have been two ways to measure pH. The first is the inexpensive method of using test strips, which requires little time or training. The second requires the use of a pH electrode or probe and because it requires more training, time, and equipment, is far more expensive. However, a hybrid application is now available that brings together the ease of use of test strips with technology to ensure preciseness.

  • 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?

  • 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.

  • 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.

  • 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

  • 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.

  • 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.

  • 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.

  • 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.
