  • 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 ...

  • Techniques for Oil in Water Analysis

    The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a ...

  • Solvent-free oil-in-water analysis

    Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

  • Comparing Oil in Water Analysis Methods

    Wilks Enterprise has published a new White Paper that discusses various oil in water methods and their correlation with regulatory methods. While the amount of oil in water is highly regulated -- it can also be a challenging measurement.  It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method.  When EPA 1664 is ...

  • How to make top-down and bottom-up sustainability converge

    Fits and starts are all too common in the sustainability world. One year you have budget for initiatives; the next you don’t. Management hails cost savings on individual projects, but they miss the big picture and fail to link progress across departmental boundaries. Bottom-up progress and top-down directives pass each other like proverbial ships in the night. But it doesn’t have to ...

  • The climb to the top

    Back in the late 1980’s when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both aeration equipment manufacturers and plant operators. As production plants got away from in-ground basins, one of the more simple innate operational checks became more challenging; ...

  • Importance of Inspecting Reservoirs

    Inspecting Reservoirs – what is the importance of them, why they are inspected, and how ROVs help pave the way for low-cost, regular maintenance. What is a Reservoir? Deriving from the French word réservoir meaning “storehouse,” a reservoir is exactly that – a storage place for water. More often than not, these bodies of water are ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • Water analysis

    A complete tap water analysis includes the determination of the pH value, the alkalinity and the total water hardness. Both the pH measurement and the pH titration by means of a standard pH electrode suffer from several drawbacks. First, the response time of several minutes is too long and, above all, the stirring rate significantly influences the measured pH value. Unlike these standard pH ...

  • Will your oil in water analysis method match the regulatory method?

    Anyone involved in field analysis of oil in water will continually get the question “Does your equipment match the regulatory method?” While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the ...

  • Oil-In-Water Analysis. Verification of Particle Counter results by optical microscopy

    For my research work, which concerns separation of liquid/liquid dispersions, I selected the Spectrex PC2200. It covers the whole range of droplet sizes which are of interest, i.e. from 0.5 to 100 microns. The procedure for analysis is very simple and results are obtained in less than a minute. This makes the Spectrex instrument very handy for use in the lab as well as for field measurements (A ...

  • New Oil Analysis Handbook

    Third edition contains more How To articles and more case studies It has been more than two years since we published the first edition of the Oil Analysis Handbook. Our original goal was to compile a comprehensive reference book of common in-service oil analysis techniques to help readers understand and choose the right technique and instrumentation for their needs. Each edition brings us ...

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • Methods of oil/fuel analysis

    PC GlobeCore can propose you to make a reclaiming test of yours example of fuel (oil) to verify the possibility of clean it. If the oil is contaminated and not suitable for use, filtration can be recommended. Or, you can also make this test by yourself using our laboratory/test-bench transformer oil vacuum regeneration system UVR. The regenerated samples exceeded yours expectations. Average ...

  • Understanding Oil-in-Water Instrument Specifications

    The measurement capabilities of oil-in-water analysis methods are described by several analytical figures-of-merit. Examples are: Range (Linear and Dynamic) Limit of Detection (LOD) Limit of Quantification (LOQ) Precision (Repeatability and Reproducibility) Sensitivity Accuracy Response Time Some or all of these are often specified by customers in the bid packages issued when selecting a ...

  • Surfactant-assisted oil-in-water monitoring

    A variety of common surfactants have been used to reduce fouling and enhance the performance of fluorescence-based oil-in-water monitors. Among the most effective are the alcohol ethoxylates with HLB values close to 12. Examples are SurfonicTM L24-9 (Hunstman, USA, HLB 13) and TergitolTM 15-S-7 (HLB 12.1). These surfactants readily convert heterogeneous oil/water mixtures into homogeneous, ...
