  • An Easy Guide to Understanding Surfactants

    What is a Surfactant? Surfactants are a primary component of cleaning detergents. The word surfactant means surface active agent. As the name implies, surfactants stir up activity on the surface you are cleaning to help trap dirt and remove it from the surface. Surfactants have a hydrophobic (water-hating) tail and a hydrophilic (water-loving) head. The hydrophobic tail of each ...

  • Ambient Air Sampling Methods

    Pollutants are nothing but any substance that may present in an atmosphere in such a concentration that it may harmful to surrounding, living organism or human being. Sampling and analysis of air pollutants is known as Air quality monitoring and it is major part of environmental monitoring. There are many advanced types of ambient air Sampling methods. we will learn here only which are most ...

  • Containment for Soil, Sediment, and Sludge

    Containment treatments are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards, ...

  • What is a Sanitary Sample Valve?

    As its name suggests, this type of valve is used in processing industries for sampling various products in different states of matter such as liquid and gas. The different types of fluids are examined using various techniques using sampling valves. Some of the main ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • Sampling of Saturated and Unsaturated Sands by Freezing

    A 600-mm-long, 100-mm-wide, and 20-mm-thick steel plate containing a wavey groove carrying chilled ethanol at -40°C was used successfully to obtain undisturbed frozen samples of saturated clean sand. The freezing probe was also used in an unsaturated sand dune to obtain samples at a depth of 3.0 m. For sands above the groundwater level, an imbibition test is, however, required prior to freezing ...

  • Eco-toxicity of oily wastes containing TENORM

    Oily wastes are considered as one of the most hazardous waste types. Additionally to petroleum components, they can contain radioactive elements. This study aimed to estimate the toxicity of four raw and two treated waste samples obtained from petroleum production yard. Eight elutriate bioassays using plants ( Raphanus sativus and algae Scenedesmus quadricauda ), crustacean ...

  • Low-Flow Groundwater Sampling- Techniques Improve Sample Quality and Reduce Monitoring Program Costs

    Ground water is often sampled to determine its water chemistry, to see if the water is acceptable for human consumption, or to sec if industrial activity may have caused contamination. Sampling ground water from monitoring wells has traditionally involved "purging" the well to remove stagnant water that may not be representative of in situ ground water quality. Regulatory guidance often ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Sample preparation for the analysis of secondary fuel in cement plants

    Secondary fuel can be a very inhomogeneous sample, containing all types of polymers, paper, wood and low fractions of metal. Also recycled wood or parts of automobile tires might be used as secondary fuel. Before using it as fuel in the production of cement, several chemical analyses are necessary as quality control. Cement is made by heating limestone (calcium carbonate), with small quantities ...
