As the world is continuously faced with environmental challenges, compliance standards and regulations must be met along with them. Soil analysis, drinking water analysis, sewage water and wastewater analysis are all required to protect the environment and our public health. Environmental contaminants to be analyzed may include inorganic anions, cations, heavy metals, organic pollutants and nutrients. The United States Environmental Protection Agencies (USEPA) Safe Drinking Water Act (SDWA) and the Clean Water Act (CWA) are the two important environmental laws governing water regulations. Clean Water Act Methods Update Rule for the Analysis of Effluent 40 CFR part 136 andmany of the regulatory bodies, such as the ASTM, ISO, DIN recommends wet chemical methods waste water analysis.
Wastewater surveillance of COVID-19 is a rapidly evolving area of research that holds great promise as an early, cost-effective, unbiased community-level indicator of the presence of COVID-19. Persistence of the genetic signal will be impacted by: pH, ammonia, phosphate and other nutrients. Other water quality parameters can provide information about the operational status of the water resource recovery facility. This can be useful in identifying the occurrence of events that may impact the strength of the genetic signal.
Manufacturing industries consuming large volumes of water produce both hazardous and non-hazardous wastewater. Treating this wastewater and reusing it is a key challenge for companies seeking to maintain a profitable operation while protecting the environment. Reclaimed or recycled water is produced by conversion of wastewater into water that can be reused for other purposes. These waters are adequately treated to meet “fit-for-purpose specifications” for next use. Wastewater testing serves two purposes:
EPA sets legal limits on over 90 contaminants in drinking water. National primary drinking water regulations (NPDWR) includes inorganic and organic chemicals, disinfection byproducts and disinfectants determination by wet chemical and ion chromatography methods.
Traditional water testing involves – multiple wet chemical instruments for multiple parameters such as Nutrient analysis, pH, Conductivity, alkalinity and hardness etc. Each test requires a separate sample and often multiple sequential steps which extends the testing process. With slow processes and the need for specialist staff to run and monitor equipment, water quality testing is labor-intensive, time-consuming and inefficient. Routine water testing can be costly and time consuming for a laboratory that performs routine nutrients, ground water, drinking water and wastewater analysis while experiencing increased demand for the routine analytical services.
Traditional wet chemistry methods like titration or ISE sequentially measure individual test parameters. For each parameter, dedicated ISE are necessary and have limited shelf lives. Each titration parameter needs a dedicated burette and sensor, as the number of parameters per sample increases, the overall system complexity increases, resulting in long hands-on sample and response times.
Consolidated multiparameter discrete analysis now offers a solution to these difficulties and offers high throughput wet chemical analysis workflow. Discrete analyzers, which consolidate and simultaneously test for up to 20 parameters — using a single instrument with a single operator. Gallery and Gallery Plus discrete analyzers are easy-to-use, automated systems that allow laboratories to simplify their testing with dual benefits: time and cost savings. All necessary analysis steps are automated, providing true walkaway time for the operator. Both Gallery and Gallery Plus instruments provide an integrated platform for two measurement techniques, photometric and electrochemical (pH and conductivity), which can be run simultaneously. Parallel determination of several analytes from a single sample as well as the presence of several automated features ensures analytical efficiency.
pH and conductivity for 100 samples can be tested simultaneously in less than 90 minutes, while the system is measuring alkalinity, hardness and other parameters. While traditional analysis requires multiple wet chemistry methods and, therefore, multiple samples, the Gallery discrete analyzer consumes a maximum of 300 μL of sample per test, can test for up to 20 parameters per sample, and runs up to 200 tests per hour.
Our discrete analyzers automate photometric and electrochemical analysis provide fast, reproducible results that allow laboratories to measure multiple analytes simultaneously, while reducing total analysis and operator time.
The Thermo Scientific Disc-IC system is a package of two independent techniques from Thermo Fisher Scientific—discrete analysis and ion chromatography for comprehensive water analysis. Unique and fully automated, the Disc-IC system combines the power of direct measurement, discrete analysis with ion chromatography to support a comprehensive water analysis workflow that offers the highest flexibility and sample throughput to reduce overall cost per analysis.
The Thermo Scientific Gallery discrete analyzer provides an integrated platform for two measurement techniques, photometric and electrochemical (ECM), which can be run in parallel. Discrete cell technology allows for simultaneous measurement of several different tests for the same sample, eliminating method changeover time. The Gallery system can achieve very low detection levels, and its sophisticated dilution features help to manage a wide concentration range without user intervention.
ECM is an integrated unit into the Gallery discrete analyzers and supports the automated pH and conductivity measurements. It is capable to simultaneously measure both pH and conductivity alongside the photometric testing. ECM is suitable for raw water, ground water, sea water, rainwater, municipal water, drinking water and waste water.
Save time by eliminating reagent preparation with the Thermo Scientific Gallery system reagents for environmental testing, such as water (clean water, waste water, soil and sludge digests, effluents, and saline) and industrial (process water) analysis. With over 40 ready-to-use gallery system reagents for environmental analysis, the kits include 1 to 3 reagents in 20 mL barcoded vials, allowing the necessary identification data, such as lot and expiration date, to be read automatically by the discrete analyzer's barcode reader. Automated dilutions make it possible to apply methods for a wide range of analyte concentrations and the test applications are based on recommended standard water and waste water methods used in most countries. Save time and reduce errors by simplifying your analysis with the Gallery system reagents for environmental analysis.
Thermo Scientific reagents are ready to go, saving the technician’s time and reducing errors. The unique low volume cuvette design guarantees small reagent volumes, minimizes reagent waste, and as a result, reduces reagent costs. Optimized kit sizes and on-board stability further minimize the amount of waste produced and increase cost efficiency.
Ensuring confidence in the quality of results, the methods used for analysis in the Thermo Scientific discrete analyzers are well known enzymatic and colorimetric chemistries optimized to the result levels established in international reference methods, US EPA, ISO, DIN, ASTM and other standard methods.
Thermo Scientific Gallery discrete analyzer with ready to use system reagents are optimized for speed, flexibility, and precision for drinking water and waste water. The unique discrete cell technology allows laboratories to measure multiple analytes simultaneously while reducing total analysis and operator time. The unique low volume cuvette design accommodates small reagent volumes, minimizes reagent waste, and as a result, reduces reagent costs.
