    Improved Reproducibility and Reduced Sample Preparation Time for the HPLC Analysis of Aflatoxins in Raw Peanut Paste

    The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often necessary. Preparation of matrix samples prior to chromatographic analysis typically requires extraction and purification. Commonly, immunoaffinity columns (IAC), which employ a multi-step bind and elute mechanism to concentrate and purify aflatoxins, are used to purify matrix samples for subsequent analysis. Solid phase extraction (SPE), an alternate method which may use interference removal, can also be employed.

    Measurement of methane, methanol and ethanol for the biomass monitoring for biofuels.

    The Series 8900 provides direct measurement of methane, methanol, and ethanol for the biofuel industry. The Series 8900 GC employs a flame ionization detector (FID). The methane, methanol, and ethanol in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the MME and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Methane, methanol, and ethanol are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

    Mercury monitoring for mercury flux measurement

    The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.

    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

  • Automated System for High Throughput PCR Setup

    Modern genomics labs are looking for high-throughput, quality-data workstations to perform PCR reactions at a reduced cost. PCR reaction setup is a tedious and time consuming process as it requires mixing multiple reagents in specific ratios to achieve the proper master mix for amplification. Moreover, the exact volumes of the reagents and buffers depend upon the total number of samples to be amplified and the desired final concentration of sample DNA. Automation of such procedures eliminates both human error and contamination problems generally associated with manual process. To provide an automated solution to such a cumbersome protocol, Aurora Biomed’s VERSA 110 PCR Setup Workstation was developed for the preparation of reagents and samples used in an amplification protocol in 96-well format.

  • 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.
