    Gas analysis & monitoring system for semiconductor

    The Cleanroom is a combined laboratory chemical, mechanical and / or electronic whose main characteristic is the presence of very pure air, that is a very low content of fine dust in suspension. In the process of semiconductor production, the airborne particles (micro-powder) go to irreparably damage the micro-photoetched that form the chip, creating an electronic circuit defective, and then discarded. This process has forced the improvement of industrial production environments, removing particles from the air, for two purposes: to increase the efficiency of production, increasing the yield of quality, and requirement of the manufacturer (of course based on the demand of the market) in shrink increasing the area of etching of semiconductors (just think of the USB storage media in a few years, went from 16 MB to 16 GB without changing the external dimensions).

  • Ambient Continuous Metals Monitoring/ Fence Line Monitoring/ Source Identification

    The Xact® 625i combined with ADAPT software creates the industry's most powerful tool for high time resolution detection of airborne metals. The Xact® 625i measures trace metals at very low detection limits at time resolutions down to 15 minutes. The ADAPT package captures corresponding wind speed and wind direction data, then seamlessly integrates the measurements into wind regression analyses available at the touch of a button. This creates the most single most powerful fence line/ source identification instrument in the industry.

  • Radionuclide Monitoring for Nuclear Power Plants

    The continuing establishment of nuclear power stations around the world pose unique environmental challenges for their operators. Ecotech provides air samplers to nuclear power plants for sampling of radionuclides. A nuclear power plant`s radionuclide monitoring network enables continuous sampling of airborne particles onto sample filters contained within High Volume Air Samplers. These filters are then analysed in a laboratory in order to screen for any radiation releases. The challenge has always been to obtain a sufficiently large volume through the filter in order to exceed the laboratory methods minimum detection limits. Ecotech`s MegaVol Sampler, samples at a flow rate of between 120-150 m3/hr providing a high flow rate in order to collect a sufficient sample mass for laboratory analysis. The MegaVol will maintain volumetric flow rate at a preset volume until the filter is either changed or overloaded. The MegaVol can be equipped with a 3G modem in order to remotely monitor flow rate and other diagnostic parameters such as temperature, pressure and wind speed and direction.

    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.

    Abatement and Remediation

    Containment and safety issues are a critical consideration when working on any mold, asbestos, or lead remediation/abatement projects. Improperly contained, the dust and bio-contaminants released can, be very harmful for both on-site workers and occupants in neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together. In most cases, however, there are four common considerations that will be relevant: -Meeting Containment and Air Change Requirements -Monitoring of Containment Pressure -Sterilization of Filtered Air -Removal of Odors, Mold Spores, VOC’s and other Airborne Bio-Contaminates
