    Oct 24, 2007 · Metal spheres are used as a standard in determining detector sensitivity capabilities because: A sphere is the only object without orientation, that is, it appears the same from every angle, and no matter which direction it goes through the detector, it should have the same effect. In addition, tests run with spheres are duplicable and measurable.

  • Detection limit - Wikipedia

    In analytical chemistry, the detection limit, lower limit of detection, or LOD, often mistakenly confused with the analytical sensitivity, is the lowest quantity of a substance that can be distinguished from the absence of that substance with a stated confidence level. The detection limit is estimated from the mean of the blank, the standard deviation of the blank, the slope of the calibration plot and a defined confidence factor. Another consideration that affects the detection limit is the acc

  • 9 Methods to Identify and Detect Microbial Contaminants in

    RisksPurposePrognosisInfluencesAssessmentApplicationsSignificanceCauseToxicityEnvironmentEvolutionOther animalsControversyDiagnosisPreparationPropertiesIntroductionScopeTypesAdvantagesMechanismVariationsConstructionSynthesisOthersUseThe transmission of infectious diseases via contaminated water continues to be a risk to public health in the United States and throughout the rest of the. world. Source and finished drinking waters are vulnerable to microbial pathogen contamination from a variety of sources of human and animal fecal wastes and from the introduction and proliferation of nonfecal pathogenic microbes. Throughout most of the modem history of drinking water supply, concerns about pathogenic microbes have focused on enteric bacteria of human fecal origin. These concerns led to the development of criteria and standards for bacteriological quality intended to protect against excessive risks from enteric bacterial pathogens such as Salmonella typhi and other nontyphoid Salmonella spp., Shigella spp., and Fibrio cholerae. The infectious disease risks in drinking water supplies from enteric viruses (such as hepatitis A virus), enteric parasites (such as Entamoeba histolytica and Giardia lamblia), and nonfecal bacterial pathogens (such as Legionella spp.) were not recognized until more recent times. These risks were recognized initially by the occurrence of waterborne outbreaks of disease mused by these pathogens. animals, often asymptomatically, and some, such as the Legionella spp., the Mycobacteria spp., and the heterotrophic plate count bacteria, have abiotic environmental reservoirs. For many of these bacteria the role of waterborne transmission has been documented by waterborne outbreaks, or it is strongly suspected because the bacteria have been detected in drinking water and its sources (see Table 9-2). In the case of some of these waterborne bacteria their risks to human health from ingestion or inhalation of water or contact with water are uncertain because they have not been conclusively documented by outbreaks or other epidemiological evidence of waterborne disease. However, their presence in drinking water and the uncertainty of their risks to human health from drinking water exposure suggest the need for further investigation and analyses. The risks posed by various bacteria potentially present in drinking water differ among the various genera and species as well as within the same genus and species of a bacterium. These differences in risks to human health pose considerable challenges to the detection and identification of these bacteria in water. Similar concerns apply to the protozoan parasites, algae, and fungi. Strains or variants of the same genus and species of bacterium can differ dramatically in their ability to cause disease because this ability is largely dependent on the presence of virulence factors or properties.

    Aug 06, 2012 · Total and faecal coliforms have been used extensively as indicators for many years to determine sanitary quality of surface waters. However, because of the great diversity of microbial pathogens, current indicators of water quality may not detect all types of microbial contamination. Some pathogens do not co-occur with faecal pollution and bacterial indicators have greater sensitivity to disinfection.

IT is a techniquethat produces an image of invisible (to the human eye) infrared light emittedby objects due to the heat, or lack thereof, in the object called its"thermal condition." The most typical type of thermography cameraresembles a typical camcorder and produces a live television picture of heatradiation. More sophisticated cameras can actually measure the temperatures ofany object or surface in the image and produce false color images that makeinterpretation of thermal patterns easier. An image produced by an infraredcamera is called a thermogram or sometimes a thermograph.2 To understand IT as a tool it is necessary to understand how it works.Thermal or infrared energy is light that is not visible to humans because itswavelength is too long to be detected by the human eye.
