  • Continuous Monitoring of BTEX and PAH using Automatic Thermal Desorption-Gas Chromatography

    Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently ...

  • Confirmation of the correlation between membrane fouling in microfiltration and biopolymer concentrations in various Japanese surface waters

    A variety of surface waters used for drinking water sources were collected from different parts of Japan to investigate a correlation between the concentration of hydrophilic biopolymer (e.g. proteins and polysaccharides) in the feed water and membrane fouling in microfiltration. Hollow-fiber membranes made from polyvinylidene fluoride with a nominal pore size of 0.1 μm were used in the ...

  • Glyphosate and AMPA in drinking water

    Carcinogenic or not? The broad-spectrum herbicide glyphosate is used all over the world in agriculture. Alongside farming, the chemical is also used for weed-killing in domestic gardens and in public and private spaces kept free from «vegetal invasion», such as railway tracks. Glyphosate has been used since the 1970s in pesticides and was hitherto thought to be harmless at ...

  • Case study - N°NG1 – Natural gas monitoring – Medor Exp

    Context & Challenges Natural gas used for household consumption typically contains odorant sulfur components for safety reasons. As natural gas is normally odorless, the sulfur components are artificially added. When natural gas is transported between various companies, regions or countries, gas companies have to verify that the sulfur species are present as specified. ...

  • Smart Infrastructure is Key for QA/QC

    Paperless, or more accurately integrated, labs enjoy streamlined operations with better data, while minimizing costs, validation and maintenance. Laboratories responsible for QA/QC are a sum of many parts, but no part is more important than data. Data is THE product, and the integrity of that data is more than critical to today’s pharmaceutical laboratories. So what happens when processes ...
