    Gas monitoring instruments and systems for fumigation

    Sea cargo containers and wooden packing materials are fumigated to control the spreading of pest animals and micro-organisms. Fumigant gases are toxic and measurements are carried out as a health and safety precaution. Measurements are required by e.g. customs inspectors prior to opening containers, making the shipping companies responsible for carrying out measurements. Products shipped in containers may release VOCs from e.g. solvents and glues used in manufacturing process. The concentrations of vapors may be significant in the confined space of the container. While most containers originate in China and Southeast Asia, cargo container measurements are done in ports across the world, as the same gases are encountered in all ports.

    Monitoring once through cooling water

    The Situation

    Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling water is taken from lakes, rivers, or the ocean and circulated once through the plant to cool processes. Large volumes of water are used to keep the return water temperature low enough to prevent adverse effects on the environment.

    Multiparameter Monitoring for Scientific and Academic Researching

    Research programmes demand both technology and affordable products to cover studies from rivers to full ocean depth.  Valeport have gained significant knowledge through close collaboration with some of the worlds leading institutes.  A clear example of this is our CTD sensor fitted to the seal tags of the Sea Mammal Research Unit (SMRU) of St Andrews University, Scotland as they monitor marine mammal behaviour within their oceanic environment, by obtaining oceanographic quality CTD casts.

    Measurement of sulphur in oil and fuels for oil & gas industry

    There is a continuing and increasing demand for a rapid, simple and cost-effective measurement of sulfur in a wide range of petroleum products including automotive, marine and aviation fuels. Benchtop EDXRF instruments such as the world renown Lab-X3500 and associated X-Supreme8000, can be found in many refinery laboratories/testing houses, with the instrument often operated by production staff on a 24/7 basis, giving accurate results conforming to globally accepted test methods, e.g. ASTM D4294, ISO20847, and the new ISO13032,etc. Both instruments used the analytical technique of Energy-Dispersive X-ray fluorescence (EDXRF) which is well regarded for its excellent performance, versatility, ease of use, speed, and cost-effectiveness.

    Water monitoring technology for coastal & estuary

    Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-bird Coastal offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications.

    Meteorological Sensors for Hydro-Meteorology Industry

    Climate change makes for more extreme weather. The main reasons for this are wind and precipitation.That is why an increasing number of meteorological and hydrological monitoring networks are coming together. Global coverage with hydro-meteorological measuring technology is varied. Very old and very modern (new) measuring networks are used for climate monitoring worldwide. And there are still large gaps, for example on the oceans.

    Gas analysis & monitoring system for soil degassing

    The migration of magma towards the surface in a volcano is usually accompanied by the release of gas that was previously dissolved in the magma itself. In an open conduit volcano, most of the gas escapes through the main conduits of the volcano and then through the craters. However, a significant proportion (approximately 10%) of the total quantity of gas can escape laterally through faults and fractures that are normally present in the flanks of a volcano. Therefore, increases in the amount of gas emitted usually indicate the initial stages of magmatic migration towards the surface.

    Mercury monitoring for ocean cruises

    Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependability and performance. If any repairs are necessary, the instrument is highly user-serviceable and easy to maintain.

    Machine condition monitoring for marine

    Overview

    Machine condition monitoring based on oil analysis has become an important, if not mandatory, maintenance practice by the marine industry. An effective oil analysis program will keep important assets such as engines, gearboxes, hydraulic systems, turbines, compressors, generators and any other oil-wetted machinery in operation by reducing unexpected failures and costly unscheduled down time.

  • Monitoring of Algal Production / Monitoring of Algae Growth

    Over the past 20 years active fluorescence has been widely adopted by the scientific community, ecosystem managers and crop growers as a rapid and non-invasive method of estimating photosynthetic performance within a wide range of organisms, including phytoplankton (microalgae and cyanobacteria), biofilms, benthic autotrophs (corals, macroalgae and sea grasses) and terrestrial plants. The main rational for applying active fluorescence is that changes in key fluorescence parameters can reveal the early onset of chronic and acute degradation of photosynthetic performance and subsequent growth, e.g. resulting from nutrient deficiency or the presence on one or more toxicants.

    Over the past 15 years we have been developing an active fluorescence technique called Fast Repetition Rate (FRR) fluorometry to monitor algae populations in the open-ocean, primarily to support climate and ocean modelling.
