Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS
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.

Total Nitrogen New Method For Analysis: Webinar
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.

Phosphate In Groundwater And Surface Water: A Rapid And Reliable Determination Method Using The Photometric Spectroquant® Test
Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO4-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.
Sensitive Determination Of Iron In Drinking Water, Mineral Water, Groundwater, And Spring Water Using Rapid Photometric Tests
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.

New Data Management Capabilities Help Labs Run Smoothly
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.
Maximizing Speed And Accuracy In Microbiological Testing
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.
Identifying Accurate Reference Materials For Water-Testing Confidence
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.
Simplified Testing For BPA In Source Water
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.
Fine Tune Your Lab Testing Accuracy With Compliant Proficiency Testing (PT)
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.
Smartphone App Delivers Reproducible And Precise pH Analysis
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.
Are Test Strips Still Relevant For Water Analysis?
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?
What's Faulty — Your Treatment Or Your Testing?
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.
Evaluating Field-Testing Options For Nutrients In Streams
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.

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.
Easier, Faster, And Safer Option For Measuring Total Nitrogen
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.
