    A New GC-MS Method for Mycotoxin Analysis Using 13C-marked Mycotoxin Derivatives

    Andreas Breidbach [1] and Wolfgang Brodacz [2,3,4] developed a new GC-MS method using fully 13C isotopelabelled analogues of T-2 toxin and HT-2 toxin that allows for the detection of these toxins at concentrations as low as 2–5 ppb.

    Laboratory Weighing - Filter Weighing

    Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.

    Monitoring petroleum hydrocarbons in wastewater

    The economic advantage of continuous discharge could only be achieved at this location by meeting strict discharge limits for the level of hydrocarbons present in the discharged water. Local ordinances required continuous monitoring for continuous discharge of the company’s treated wastewater.

    Waste water treatment plants Personnel Safety & H2S filter management

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

    Air quality monitoring

    To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.

    Aqua M300 Intelligent Geophone

    With the Aqua M300 leak detectors have a multifunctional tool to Pinpoint or Pre-locate leakages and to trace pipes in conjunction with a PWG. The biggest advantage compared to other related products are the 256 analogue and digital filters which enables the user to shut off disturbing noises very precisely. Also the extension for H2 tracer gas comes without competition and makes this device a essential tool for leak detectors.

    Monitoring solutions for the process monitoring

    Maintain specification in your process stream or bench top setup with a Cerex process analyzer. Cerex UV3000 F Series analyzers accurately detect gases from ppb level to percent level concentrations via a fiber coupled probe for precise control of a process stream. The F series are also well suited to fiber couple to a custom cell for laboratory analysis, and feature user programmable alarm levels to control process functions or give warning when a process filter needs replacement. Cerex analyzers are also available customized to customer specification.
