  • Fluorophenyl LC Phases- what you should know

     They may be called PFP, PFPP, pentafluorophenyl, fluorophenyl or F5 phases. What they all have in common is the structure shown above (the pentafluorophenyl  group) attached to the silica particles. Most modern phases contain a propyl spacer between the above group and the silica, so that the phase looks something like this: ...

  • Making a TO-15 Working Standard and the Super Standard Calculator – V2.01

    We already learned how to calibrate our TO-15 system, what our concentration units mean, and how to properly read our vacuum gauge while pressurizing samples. We are clearly going out of order here, because I have never covered how to prepare a working standard (necessary for ...

  • Case study - TPH in produced sand for overboard discharge

    Customer uses TD-500D to measure TPH concentrations in produced sand on an offshore oil platform in Malaysia.  The sand contains high levels of crude oils and must be treated on-site prior to dumping it overboard.  The TD-500D was calibrated to Sitelab's TPH calibration kit, product CAL-056.  Methanol solvent was used to extract the samples.  For comparison, samples were also ...

  • Measurement Science and Technology Paper - Potential for improved radiation thermometry measurement uncertainty through implementing a primary scale in an industrial laboratory

    A primary temperature scale requires realising a unit in terms of its definition. For high temperature radiation thermometry in terms of the International Temperature Scale of 1990 this means extrapolating from the signal measured at the freezing temperature of gold, silver or copper using Planck's radiation law. The difficulty in doing this means that primary scales above 1000 °C require ...

  • Case study - Texas crude oil in soil sites

    Sunset Well Service, Inc. is an environmental contractor located in the Midland/Odessa area of Texas. They use their UVF-3100D analyzer to help excavate and remediate soils contaminated by produced water and crude oil. Laboratories in Texas test TPH using the TX 1005 GC-FID Method. This method is similar to U.S. EPA Method 8015M, but reports the GRO, DRO and ORO fractions separately. Soils from ...

  • Environics - Full-scale error vs. Setpoint error

    A flow controller's accuracy is typically expressed as a percent of Full-Scale flow (%FS). This means that the flow controller is most accurate when operating at its rated full-scale flow rate. This also means that its accuracy, expressed as a percent of Setpoint, drops off significantly when operating at lower flow rates. For example, a 1000 cc/min flow controller with a +/- 1%FS accuracy, ...

  • Free-field calibration in China

    Practically all reference microphone calibrations that are performed by national metrology institutes are pressure response calibrations. This is the case even if most practical measurements are carried out under free- or diffuse-field conditions. Fortunately, for measurement microphones, there are essentially fixed ratios between the pressure-, free- and diffuse-field responses. Therefore, the ...
