Hygienic Applications

Hygienic applications do not necessarily provide any protection to the plastic article itself, although by their nature could do so. They provide protection against organisms that may come into contact or settle on them, thereby limiting transmission of disease.

The availability of the initial material and its relative cheapness make this type of SAH highly attractive from a practical viewpoint. They are manufactured commercially by a number of companies for agricultural, sanitary, and hygienic applications. 

Non-woven fabrics can be produced very economically, which suits them for many singleuse health and hygiene applications, such as the outer cover and body contacting layers of... 

Even in the absence of light a decrease in cell growth was observed compared to unmodified BC. These materials are recommended for use as bactericidal surfaces in medical, healthcare, and hygienic applications [60]. 

Silicone-coated papers and films find their application in many areas where release of an adhesive is needed. By far the biggest application can be found in the label industry. Other applications can be found in graphic art and in hygiene applications, e.g. in diaper tapes. Another big area where these products can be found is that of bakery and food, in which silicone-coated paper can give release against bakery products or act as grease-proof wrapping paper. 

A coated surface-acoustic-wave (SAW) sensor capable of real-time, selective measurement of vinyl acetate vapor in the presence of several olefin and non-olefin cocontaminants is described. The coating film en loyed consists of the solid platinum-ethylene Ji-complex, trans-PtCl (ethylene)(pyridine). occluded in a polyisobutylene matrix. Exposure to vinyl acetate results in displacement of ethylene from the cott lex and formation of the vinyl acetate-substituted complex. Subsequent regeneration of the original reagent is possible by treatment with ethylene gas, in situ. A lower detection limit of 5 ppm of vinyl acetate is achieved for operation at 46 C. The industrial-hygiene applications of the sensor are discussed.

A device that detects the presence of various gases within an area, usually as part of a system to warn about gases that might be harmful to humans or animals. Various types of gas detectors are used to detect primarily combustible, toxic, and oxygen levels (i.e., deficiency), and carbon monoxide and carbon dioxide gases. They are typically used in confined spaces, utilities and chemical plants, industrial hygiene applications, and air quality testing. They can be fixed devices or portable devices worn by an individual. See also Combustible Gas Detector.

A review of the diverse food hygiene applications of impedance microbiology has recently been published [243]. The detection of Enterohacteriaceae, particularly Salmonella spp., the determination of total bacterial counts, and the examination of antibiotics and food additives for an-timicrobiological effects are important. Another short review describes a model explaining the effects of microbial growth and metabolism on capacitance at electrodemedium interfaces [244]. 

At present, four companies provide specialized impedance measurement instrumentation for chnical microbiology or food hygiene applications. BioMirieux manufactures the Bactometer, which can monitor conductance, capacitance, or impedance in up to two temperature-controlled incubators, each containing 256 samples. Malthus Instruments produces... 

In previous chapters we mainly discussed solid electrolyte gas sensors designed for application at increased temperature. In the present chapter our attention will be focused on the ambient-temperature liquid and polymer electrolyte gas sensors which are used mostly for medical and industrial hygiene applications. As shown in Chap. 1 (Vol. 1), electrochemical gas sensors usually include filter, man-brane (or capillary), electrolyte solution - in which the two or three electrodes (working or sensing electrode, WE, reference electrode, RE, and counter electrode, CE) are immersed, and manbrane. The electrochemical gas sensor produces a current or voltage when exposed to a gas/vapor containing an electroactive analyte because the analyte diffuses into the electrochemical cell, to the working electrode surface, and thereon participates in an electrochanical reaction that either prodnces or consumes electrons (i.e., a redox reaction) (Stetter et al. 2011).
