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...

Application of Ion Mobility Spectrometry for Determination of Morphine in Human Urine

In this study, a rapid, simple and sensitive ion mobility spectrometry (IMS) method with corona discharge as ionization source was described for the morphine determination in human urine. Morphine was extracted and purified from urine samples using solid phase extraction procedure with C18 column. It can offer the clean extracts which no extra peaks were observed in IMS. Under operating experim...

Ion Mobility Mass Spectrometry

for more complex analysers for automated sample processing and plant control. The separation time will continue to decrease; in the past there has been limited interest in fast separations but this could change as automated sample processing is developed. Increasing use of coupled techniques such as GC-GC, liquid chromatography-GC, and supercritical Suid chromatography-GC for the separation of ...
