    Analysis of Herbicides in Drinking Water

    Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases that are available. In particular, several HPLC phases are available that provide great retention and peak shapes for polar analytes, such as herbicides, even under mostly aqueous mobile phase conditions. The combination of these factors may possibly eliminate need for time-consuming sample preparation.

    Oil in Water Analysis for Flowback or Produced Water

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote lab results can take several days to a week. InfraCal TOG/TPH Analyzers allow for oil in water testing at the well site in less than 10 minutes. The sampling requires a few simple steps that can be performed by non-technical personnel. The water is mixed with the extraction solvent, shaken, and then presented to the analyze for measurement. The same InfraCal TOG/TPH Analyzer can be used for TPH in soil if a spill or pond leak occurs to determine the contaminated area. The analyzer features: -Results in under 15 minutes -Detect levels as low as 10 ppm -Portable, rugged, lightweight, easy-to-use -Battery operable -Ideal for field or lab use

  • Analysis of aqueous solutions

    IR-Spectroscopy is not limited to gases, solid materials and pure liquids but also facilitates the measurement of solutes in aqueous media. Though, due to the strong and temperature dependent absorption of water, the usage of conventional IR-transmission and ATR accessories is not very suitable for the analysis in water. The CONFOCHECK is a dedicated FT-IR system for the fast, easy and sensitive analysis of aqueous samples. Using this system, preparing, measuring and evaluating any aqueous sample takes typically about 1 minute.

  • Agricultural, Storm and Highway Runoff

    The ability to collect useful data about sediment transport and other pollutants closely coupled to SSC (such as nutrients, e-coli, phosphates and nitrates) is dependent on the timing and frequency of manual grab samples during run-off events. Most sediment and pollutant is transported during a small number of storm events which are infrequent and unpredictable. When they do occur, trained personnel or the proper equipment may not be available to collect grab samples. An automated pump sampler can eliminate the need to sample manually, but for the expense of a rechargeable power system, the autosampler, and possibly a datalogger and a typical turbidity probe, you’re no better off. With an automated pump sampler driven by the DTS-12 digital turbidity sensor and controlled by the Axiom H2 datalogger, you obtain a better understanding of the water’s quality, while taking a minimum number of samples, reducing site visits and saving lab analysis costs.

  • EPR waste minimisation monitoring for wastewater treatment industry

    The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a point scoring system to assess operators under the OMA-3 program and this will be used to identify how well a company is managing their processes and possibly identify areas for improvement. The Environmental Permitting Regulations require industry to install instrumentation (MCERTS approved where available) to report water quality. EPR compliance monitoring may include automatic water sampling, flow measurement, pH, turbidity and TOC water analysis. Industry will need to identify point of source emissions, take steps to correct inefficient control and alarm unacceptable process deviations. Although the legislation focuses on environmental improvement, good housing keeping also makes a lot of sense. Optimisation of process control minimises waste, reduces treatment costs and ultimately saves money.

    Gas monitoring instruments and systems for process NOx measurement

    Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

  • Environmental Monitoring

    Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.

    This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.

    Although applications in this area advance, there is still a clear demand to get new portable and versatile analysis systems for many different application fields such as pollution in environmental or waste waters, monitoring nutrients in agricultural or horticultural water as well as general process control in chemistry industry. Because of the number of enviromental analysis required, there is a need for screening and monitoring measurements of these compounds at contaminated areas.

    Traditional monitoring techniques are typically based on laboratory analysis of field-collected samples that require considerable effort and expense, and the sample may change before analysis. Moreover, the equipment currently available is too large and expensive and it cannot be made portable.Alternatively, microfluidic and electrochemical sensor technologies can contribute to the development of new portable monitoring systems, complementing standard analytical methods for different environmental monitoring applications.In this way, the decentralization and integration of all those typical analyses is the paramount importance in order to reduce cost, simplify the analytical process and make more accessible these technologies to end-users. The development of portable, robust, and accurate Lab-on-a-Chip systems to monitor priority compounds such as contaminants, explosives, chemical warfare agents, inorganic and organic ions is a demand of modern society. Portability allows analyses to be carried out outside of the laboratory, minimizing the risk of contaminating the sample and leading to a faster response time at a lower cost.

    Thus, MicruX solutions and technologies open the gate to develop portable and esay-handly Lab-on-a-Chip devices in order to improve pollutants in-situ analysis in a very economic and efficient way.
