Book Description
This report evaluates the methods of analysis that can be used with the Hanby Test Kits for assessing the total petroleum hydrocarbon (TPH) contamination in environmental matrices. This field screening technique is based on the colorimetric analysis of petroleum products in soil and water matrices, following a solvent extraction and a Friedel-Crafts reaction. The methods include visually comparing the sample to reference photographs, and two spectrophotometric (H.E.L.P. Mate 2010 and 2000) systems designed to establish discrete values. To test these field screening techniques, 90 field and quality assurance (QA) samples were obtained. Both of the spectrophotometric methods experienced instrumental problems, so that fewer than 60% of the samples distributed could be analyzed on-site. Ultimately, the H.E.L.P. Mate 2010 was dropped from the evaluation altogether. Furthermore, because of these complications, no TPH values were reported during the field exercise. The results yielded by the visual and H.E.L.P. Mate 2000 methods were compared for the QA samples; the visual technique was more reliable for showing the presence and estimating the quantity of TPH contamination.

Book Description
Ground water sampling and analysis are large efforts in terms of manpower and cost. The primary water contaminants from petroleum sources are the aromatic constituents due to their solubility in water. A commercially available field test kit (Hanby Analytical Laboratories, Inc.) was evaluated for application of on-site detection of low level contamination of water by aromatics. The results obtained using this kit are compared with those obtained in the laboratory using gas chromatographic methods.

Book Description
Handbook of Immunoassay Technologies: Approaches, Performances, and Applications unravels the role of immunoassays in the biochemical sciences. During the last four decades, a wide range of immunoassays has been developed, ranging from the conventional enzyme-linked immunosorbent assays, to the smartphone-based point-of-care formats. The advances in rapid biochemical procedures, novel biosensing schemes, fully integrated lab-on-a-chip platforms, prolonged biomolecular storage strategies, device miniaturization and interfacing, and emerging smart system technologies equipped with personalized mobile healthcare tools are paving the way to next-generation immunoassays, and are all discussed in this comprehensive text. Immunoassays play a prominent role in clinical diagnostics as they are the eyes of healthcare professionals, helping them make informed clinical decisions via confirmed disease diagnosis, and thus enabling favorable health outcomes. The faster and reliable diagnosis of infections will further control their spread to uninfected persons. Similarly, immunoassays play a prominent role in veterinary diagnostics, food analysis, environmental monitoring, defense and security, and other bioanalytical settings. Therefore, they enable the detection of a plethora of analytes, which includes disease biomarkers, pathogens, drug impurities, environmental contaminants, allergens, food adulterants, drugs of abuse and various biomolecules. - Provides a valuable increase of understanding of cellular and biomedical functions - Gives the most updated resource in the field of immunoassays, providing the comprehensive details of various types of immunoassays that need to be performed in healthcare, and in industrial, environmental and other biochemical settings - Discusses all multifarious aspects of immunoassays - Describes the immunoassay formats, along with their principle of operation, characteristics, pros and cons, and potential biochemical and bioanalytical applications - Provides extensive knowledge and guided insights as detailed by experienced, renowned experts and key opinion makers in the field of immunoassays
