Spatial Ion Peak Compression and its Utility in Ion Mobility Spectrometry

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 ...

Ion Mobility-Mass Spectrometry

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...

Development of atmospheric pressure ionization ion mobility spectrometry and ion mobility spectrometry mass spectrometry

Hadamard transform ion mobility spectrometry.

Traditionally, the spectrum acquired using ion mobility spectrometry (IMS) is an average of multiple experimental cycles. Each cycle is initiated by passing a short burst of ions into a drift tube containing a homogeneous electric field. Prior to starting the subsequent cycle, all ions in the system must arrive at the detector or spectral overlap may occur. To maximize resolution, the ion pulse...
