	Urine diagnostic Reagent Test Strips
		The reagent pads react with the sample urine to provide a standardized visible color reaction within 30 seconds to one minute depending on the specific panel screen.
		Depending on the test and specific reagent panel, abnormal levels of specific chemical compounds contained in urine can be easily and readily identified as potential risks factors to overall health and/or indicators of underlying health problems.
		Each of the ten reactive reagent pads on the test strip are compared to the corresponding line of color blocks on the chart.

	Reagent unit intended for microanalyses of standard type and device and method for its production - Patent 4062652
		The reagent dose can be situated either within a limited area on a carrier of band form, for example a plastic strip, or may consist of an exactly cut length of a wire or bead of reagent on such a carrier.
		The apparatus may be such that the reagent dose expelled at the point of the pipette in highly viscous or gelatinous form is separated from the point of the pipette by a knife-edge or a sharp edge, for example the edge of a tubular carrier passing said tip.
		Common to all kinds of chemicals in reagents, and which are exemplified in groups A, B and C, is that the reagent unit must be definitely obtainable in the correct quantity at a given time.

	Reagent - Wikipedia, the free encyclopedia
		For example hydrochloric acid is the chemical reagent that would cause calcium carbonate to release carbon dioxide.
		Similarly, but less obvious, hydrochloric acid is the chemical reagent that reacts with zinc to produce hydrogen, even though in this case the hydrogen comes from the acid and not the metal.
		In another use of the term, when purchasing or preparing chemicals, "reagent." describes chemical substances of sufficient purity for use in chemical analysis, chemical reactions or physical testing.

	OHS - Chemical Waste Management
		When chemicals are received take all precautions to store them according to manufacturers' recommendations such as by refrigeration, under an inert atmosphere or in a dessicator.
		Also get rid of chemicals that tend to form peroxides or become more reactive with time that are approaching the end of their shelf life.
		Reagent grade chemicals are very expensive to dispose of compared to routine chemical wastes generated by research and education.

		Although chemical modification can be defined as any alteration of the covalent structure of a protein via introduction or removal of a chemical group, we use a more restrictive definition in the context of this chapter.
		This is particularly true in cases where chemical modifications are to be used in the construction of hybrid molecules or where loss of biological activity as a result of a modification must be reacquired.
		The reagents discussed here have been selected on the basis of (1) their widespread use, and (2) the purpose behind the modification reaction (i.e., the introduction of a reporter group, the alteration of the charge of a residue, or their reversibility).

	Glucose medical monitoring system - Patent 4637403
		The chemical reagent is sealed inside the Med-Point probe housing or inside a specific housing for the chemical reagent obviating the effects of contamination (from fingers), moisture, and light, thus improving accuracy and precision of measurement by stabilizing the oxidation reduction or chemical reaction of the reagent prior to use.
		The blood sample on reagent strip 94 is processed by chemical reaction inside reagent strip 94, and color change of strip is read from the opposite side of reagent strip 94 by reflection of light from LED 50 to the phototransistor 52.
		The blood sample on the reagent strip 184 reacts with the reagents in the reagent strip 184 and the resulting color change is read from the opposite side by optical sensor 172, whose signals are converted by electronics into a numerical readout on display which reflects the glucose level of the blood sample.

	A Citizen's Guide to Chemical Dehalogenation
		Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous.
		The dehalogenation reaction occurs when several chemicals including sodium hydroxide (a base) are mixed with the condensed contaminants and heated in the reactor.
		Characteristics of the contaminated material that interfere with the effectiveness of chemical dehalogenation are high clay or water content, acidity, or high natural organic content of the soil.

		With a reagent pressure only 1% of a traditional CI source, the contamination from the reagent is all but eliminated.
		Unlike sourced MS detectors, the Saturn GC/MS requires only a very low CI reagent pressure, so a variety of liquids may be used in the place of gaseous reagents.
		For example, methanol is a "hard" CI reagent giving spectra similar to methane CI while acetonitrile provides a "softer" ionization similar to that obtained with isobutane or ammonia.
