Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA –...
Monitoring of liquid matrices by Gas Chromatography using a simplified and enhanced headspace sampling system
Chromatotec® presents a headspace sampling system designed to extract representative samples from the liquid phase. The vaporized sample can be preconcentrated using a trap to achieve quantification at very low concentration levels (ppb and/or ppm). Then, it is injected automatically and in continuous mode into the auto-GC analyzer. Speciation of sulfur compounds or VOCs is done with a MEDOR®...
Inert gas blanketing is a process used to protect volatile, combustible or perishable products from undesirable reactions such as oxidation or explosion. Gases such as nitrogen, helium or argon are used due to their non-reactive properties. These gases are introduced to purge the oxygen within a chamber, storage container, tank or any headspace within an area containing materials that require protection.
As food safety concerns raise globally, Teledyne Tekmar offer solutions for not only safety but quality as well. Whether you need to profile aromas, investigate off-odor, qualify water for ingredient processing, or measure pesticides for produce safety. Our world class instrumentation can help you feel confident and assured in your analytical results.
Ion Science leading PID sensors are recognised around the world by original equipment manufacturers for their longevity, stability and critically their resistance to humidity, so are ideal for deployment across a wide range of testing environments and diverse applications.
Aroma real-time quantification with PTR-MS. Rapid screening for complex aroma systems. Rich chemical fingerprints due to soft ionization. Real-time sampling: high throughput. Ideal for chemometric data-mining methods.
Teledyne Tekmar is the laboratory`s choice for the analysis of gasoline additives, sight evaluation to determine underground storage tank integrity, and oil profiling. The complex processes involved in the petrochemical industry result in the production and management of Volatile Organic Compounds (VOCs) and Total Organic Carbon. Teledyne Tekmar is there to make sure the measuring and monitoring of these compounds is indisputable, accurate and reliable.
Bacteriological biodegradation is used to treat certain waste water streams however excesses of some solvents will poison the bacteria reducing their efficiency. Consequently there is value in being able to quickly measure concentrations of these critical solvents so they can be pretreated/diluted to protect the bacteria.
Our purpose built environmental laboratory provides accurate and efficient analysis, specialising in the determination of gaseous pollutant concentrations. Other processes can also be performed to meet the specific needs of our customers.
Carbon dioxide and oxygen headspace analysis for food and pharmaceutical applications. To ensure product packaging integrity and shelf life, many food and pharmaceutical products are packaged using MAP Modified Atmosphere Packaging. Systech Illinois headspace gas analyzers offers fast, accurate MAP analysis of headspace in gas flushed food and pharmaceutical products.
The OVT container is an innovative product and a highly effective tool for the preliminary testing of media/soils that have been impacted by a wide variety of volatile organic contaminants of concern (COC’s).
• No preparation or modification needed prior to use in field
• Air tight OVT lid has built in sealed sampling ports of varying sizes to accommodate different size OVA probes.
• Lids snap together so all samples from one well/boring can be easily grouped together.
• Reduced potential for injury to...
Control Asphalt Odors Naturally: The production of hot mix paving asphalt generates odors that can be strong, persistent, and a nuisance to employees and neighbors alike. Controlling and abating these odors can be a challenge.
