1. Determination of benzene in urine and breath for monitoring of benzene exposure
Sammanfattning : The aim of this work was to develop and validate methods for determination of unmetabolized benzene in breath and urine. The methods were intended for the bio monitoring of benzene to assess both occupational and environmental exposure.A method was developed for the determination of benzene in end-exhaled air. LÄS MER
2. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling
Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract. LÄS MER
3. Practical and physiological aspects of breath alcohol analysis
Sammanfattning : Breath alcohol analysis constitutes sufficient material for the prosecution of drunk driving without the need for blood analysis. However, the prevailing method used for breath analysis lacks standardization of several physiological variables that cause a variation of the breath alcohol concentration (BrAC). LÄS MER
4. High Performance Breath Analysis
Sammanfattning : Alcohol breath testing on a larger scale will save lives. Alcohol abuse is a major contributor to death and disease. Alcohol intake affects the human body by significantly longer response time to external stimuli. In situations where the senses need to be on alert this delay can be the difference between life and death. LÄS MER
