DETECTION AND MEASUREMENT OF ACETONE IN THE BREATH OF DIABETICS BY ION MOBILITY SPECTROMETRY METHOD

Background: The ion mobility spectrometry (IMS) is an analytical technique that is widely used due to its high sensitivity and speed for the detection of ionized molecules in gas phase and under atmospheric pressure. Breath analysis is a new method for obtaining information about person's clinical conditions that is considered by researchers. Human exhaled air contains a variety of components s...

Breath acetone monitoring by portable Si:WO3 gas sensors.

Breath analysis has the potential for early stage detection and monitoring of illnesses to drastically reduce the corresponding medical diagnostic costs and improve the quality of life of patients suffering from chronic illnesses. In particular, the detection of acetone in the human breath is promising for non-invasive diagnosis and painless monitoring of diabetes (no finger pricking). Here, a ...

Influence of Ethanol on Breath Acetone Measurements Using an External Cavity Quantum Cascade Laser

Broadly tunable external cavity quantum cascade lasers (EC-QCLs) in combination with off-axis integrated cavity enhanced spectroscopy (OA-ICOS) provide high molecular gas sensitivity and selectivity. We used an EC-QCL in the region of 1150–1300 cm ́1 in both broadband scan mode, as well as narrow scanning mode around 1216 cm ́1, respectively, for detection of acetone in exhaled breath. This wavel...

Micropreconcentrator in LTCC Technology with Mass Spectrometry for the Detection of Acetone in Healthy and Type-1 Diabetes Mellitus Patient Breath

Breath analysis has long been recognized as a potentially attractive method for the diagnosis of several diseases. The main advantage over other diagnostic methods such as blood or urine analysis is that breath analysis is fully non-invasive, comfortable for patients and breath samples can be easily obtained. One possible future application of breath analysis may be the diagnosing and monitorin...

Carbon Nanotube Based Chemical Sensors for Space and Terrestrial Applications

A nanosensor technology has been developed using nanostructures, such as single walled carbon nanotubes (SWNTs), on a pair of interdigitated electrodes (IDE) processed with a silicon-based microfabrication and micromachining technique. These sensors have been exposed to nitrogen dioxide, acetone, benzene, nitrotoluene, chlorine, and ammonia in the concentration range of ppm to ppb at room tempe...
