  • 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 ...

  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • Barnett Shale Fault Detection

    OBJECTIVE OF THE PETRO-SONDE SURVEY: To delineate faults within Barnett Shale Barnett Shale deposits within the Ft. Worth Basin produce primarily gas from fracture porosity. Strata in the Johnson county area dip and thicken to the northeast in response to the Central Texas uplift bordering the Ft. Worth Basin to the southwest. Faulting is common in the area and generally trends NW-SE. To ...

  • How Often Should Gas Detectors be Calibrated and by Whom?

    Calibration frequency is one of the most commonly asked questions concerning the use of gas detection instruments. Common factors to consider when deciding how frequently to calibrate are: type of sensor, type of gas detector (fixed vs. portable), the required use and accuracy of the detector, manufacturer’s recommendations, how confident you are about the functioning of your instrument ...

  • Sonic nozzles for gas calibrators, when simplicity provides accuracy!

    Gas analyser’s calibration is a task required in many applications according to either legislation or quality systems management. This is the case for Air Pollution Monitoring or Continuous Emissions Monitoring devices installed in cabinets, for continuous analysis in remote locations. Measurements in traces range are performed and analytical devices specifications need to be validated and ...

  • Gas Monitor Bump Testing vs Calibration

    We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...

  • Detection and measurement of toxic gases from destructive testing of batteries

    Problem Statement New formulations of organic-compound-based batteries for vehicle use must be tested for release of potentially harmful and toxic gases if crushed in accidents. Potential gases include hydrocarbons, fluorocarbons, and hydrogen fluoride, released within seconds of an incident. Actual time-resolved and quantitative data are required from destructive testing to ascertain ...

  • Comparison of three global optimization algorithms for calibration of the Xinanjiang model parameters

    The Xinanjiang model, a conceptual rainfall-runoff (CRR) model with distributed parameters, has been successfully and widely applied to flood forecasting of large basins in humid and semi-humid regions of China. With an increasing demand for timely and accurate forecasts in hydrology, how to obtain more appropriate parameters for CRR models has long been an important topic. These models have a ...

  • CFD modelling of sampling locations for early detection of spontaneous combustion in long–wall gob areas

    In this study, computational fluid dynamics (CFD) modelling was conducted to optimise gas sampling locations for the early detection of spontaneous heating in longwall gob areas. Initial simulations were carried out to predict carbon monoxide (CO) concentrations at various regulators in the gob using a bleeder ventilation system. Measured CO concentration values at these regulators were then used ...

  • Gas Analyser Unit

    Gas Analysers are used in several industries, chemical industries in particualr use gas analysers to monitor their gas emission levels, air quality samples are compared to high purity reference gases to analyse and measure the emissions.  A common practice is to “calibrate” the sample air against clean, dry pure reference gases such as H2, He, Ar, or N2. The ...
