	Breath analyzer (Site not responding. Last check: 2007-10-02)
		The breath analyzer is an instrument that detects alcoholic impairment by measuring the concentration of
		The breath analyzer collects specimens of breath and, using any of a number of available chemical laboratory techniques, quickly determines the percentage of blood alcohol concentration (BAC).
		Breath analyzer results are accepted as evidence in all 50 states.

	Volatile Organic Compounds as Breath Biomarkers for Active and Passive Smoking (Site not responding. Last check: 2007-10-02)
		Single breath samples collected in evacuated canisters and analyzed independently with gas chromatography/mass spectrometry confirmed the presence of the target compounds in the postexposure breath of the nonsmokers but indicated that there was some contamination of the breath analyzer measurements.
		The cycles are sufficiently brief that the breath concentrations preceding the 2nd, 3rd, 4th, and 5th puffs are nonzero and are the reason that both the measured and modeled plots show a distinct buildup in breath level with each puff at the upper as well as at the lower end of each cycle.
		Although the breath analyzer may have overestimated the postexposure breath concentrations of the nonsmokers, for the reasons noted above, we nevertheless used the data to compare the background-corrected concentrations of benzene, 1,3-butadiene, and 2,5-dimethylfuran in the breath of the nonsmoker and smoker during each 2- to 2.5-hr smoking session.

	National Motorists Association
		When he first began to look into the accuracy of breath alcohol testing, very few of his colleagues had ever considered staging an analysis of breath testing methodology that would actually reflect conditions that might be seen in the field by law enforcement officers administering such tests to suspected drunk drivers.
		The type of breath analyzer to be used and the type of breath-alcohol simulator used to calibrate the aforementioned device were major concerns, not to mention the great uncertainties stemming from biological variance among test subjects.
		These results led Simpson to conclude that breath tests should not be used for evidentiary purposes unless the results yield a number high enough to make the many uncertainties associated with breath tests a irrelevant.

	Breath analyzer mouthpiece system - Patent 4900514 (Site not responding. Last check: 2007-10-02)
		Breath analyzers such as the portable breath testers used by police for the screening of drivers suspected of driving while under the influence of alcohol require the delivery of a sustained breath sample by the person being tested.
		Another case where breath testing may be performed without direct supervision and where attempts at evasion may be a problem is in a "home arrest" or remote confinement system wherein a prisoner is confined to a designated location and monitored from another location for compliance with behavioral restrictions including abstinence from substances such as alcohol.
		It is a further objective of the present invention to provide a mouthpiece for a breath analyzer which may be adapted to help detect, and therefor deter, attempts to transfer the mouthpiece between the desired test subject and an accomplice or a bogus delivery device such as a balloon or gas bottle.

	Breath Analyzer Accuracy
		Breath analyzers are a major tool in convicting such dangerous offenders.
		Breath analyzers (Breathalyzer, Intoxilyzer, Alcosensor, Alcoscan and BAC Datamaster are common brand names) don't actually test blood alcohol concentration (BAC), which requires the analysis of a blood sample.
		Breath testers can be very sensitive to temperature and will give false reasings if not adjusted or recalibrated to account for ambient or surrounding air temperatures.

	DUI expert witness alcohol
		When one plots the breath alcohol and the venous blood alcohol simultaneously measured shortly after drinking, the breath analyzer curve rises first with the venous blood alcohol lagging behind until it intersects with the declining curve of the breath analyzer.
		The reason for the difference between the breath analyzer alcohol concentration and the venous blood concentration is the buffering effect of the muscles on the amount of alcohol circulated in the blood.
		The breath analyzer measures a disproportionate share of portal vein blood alcohol, which reaches the lung early but does not have sufficient time to equilibrate with the brain cells as it is removed by the muscle and the liver.

	End tidal breath analyzer - US Patent 6544190 (Site not responding. Last check: 2007-10-02)
		Irregular breath patterns can make it difficult to determine the beginning and end of an end tidal phase, and can cause disassociations between carbon monoxide and carbon dioxide measurements due to the different sensor response times, and due to variations in the depth (shallow or deep) or timing of the subject's breathing.
		As explained in the '875 patent, the primary components of the end tidal breath analyzer are the gas sensors, the filters, the pump, the flow regulator, the sampling tube, and the tubing.
		Breath variability, caused by turbulent or excessive irregular breath patterns, can cause high variability in the calculated duty cycles, due to high variations in depth or timing of breath cycles.

	Hurley v. Director of Revenue - Missouri DUI Lawyers (Site not responding. Last check: 2007-10-02)
		Driver was observed for the requisite amount of time and then given a breath analyzer test, which revealed a blood alcohol concentration level of.161%.
		Director's first point on appeal alleges the trial court erred in finding Director failed to prove proper maintenance of the breath analyzer machine in that Director established her prima facie case which driver failed to rebut with any evidence.
		In this point, Director argues she presented evidence that the breath analyzer machine was maintained by a qualified operator within thirty-five days before driver's breath test, notwithstanding the corrections to the report and that driver presented no evidence proving the breath analyzer machine had not been properly maintained.

	Infrared breath analyzer with calibration provisions and related method - Patent 5422485 (Site not responding. Last check: 2007-10-02)
		The present invention relates to breath analyzing instruments utilizing infrared radiation to measure the amount of alcohol in a breath sample, and specifically, an improvement in calibration of such instruments.
		A typical breath alcohol measuring instrument utilizes infrared radiation (IR) to calculate the content of ethyl alcohol (ethanol) in a breath sample, from which blood alcohol content is readily calculable.
		A person being tested blows a breath sample into the chamber and infrared radiation attenuation at at least two different wavelengths is monitored during the residence time of the breath sample in the chamber.
