Ion Mobility Spectrometry of Heavy Metals
Analytical Chemistry, 2016A simple, fast, and inexpensive method was developed for detecting heavy metals via the ion mobility spectrometry (IMS) in the negative mode. In this method, Cl(-) ion produced by the thermal ionization of NaCl is employed as the dopant or the ionizing reagent to ionize heavy metals.

Hadamard Transform Ion Mobility Spectrometry
Analytical Chemistry, 2005Traditionally, 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 ...

Ion Mobility-Mass Spectrometry of Glycoconjugates
2019Glycoconjugates are diverse biomolecules that are dynamically assembled to regulate and fine-tune numerous cellular processes. Their biosynthesis is nontemplate-driven, achieved stepwise in discrete locations within the cell, giving rise to a range of complex branched structures that pose a significant challenge in structural biology. Mass spectrometry

Hadamard Transform Ion Mobility Spectrometry
Analytical Chemistry, 2006A detection scheme that makes use of the Hadamard transform has been employed with an atmospheric-pressure ion mobility spectrometer fitted with an electrospray ionization source. The Hadamard transform was implemented through the use of a linear-feedback shift register to produce a pseudorandom sequence of 1023 points.

Voltage Sweep Ion Mobility Spectrometry
Analytical Chemistry, 2011Ion mobility spectrometry (IMS) is a rapid, gas-phase separation technique that exhibits excellent separation of ions as a standalone instrument. However, IMS cannot achieve optimal separation power with both small and large ions simultaneously. Similar to the general elution problem in chromatography, fast ions are well resolved using a low electric ...

Surface Ionization Ion Mobility Spectrometry
Analytical Chemistry, 1998A surface ionization (SI) source was designed and constructed for ion mobility spectrometry (IMS). Compared with a conventional (63)Ni source, the surface ionization source is as simple and reliable, has an extended dynamic response range, is more selective in response, and does not have regulatory problems associated with radioactive ionization ...

Fundamentals of Trapped Ion Mobility Spectrometry
Journal of the American Society for Mass Spectrometry, 2014Trapped ion mobility spectrometry (TIMS) is a relatively new gas-phase separation method that has been coupled to quadrupole orthogonal acceleration time-of-flight mass spectrometry. The TIMS analyzer is a segmented rf ion guide wherein ions are mobility-analyzed using an electric field that holds ions stationary against a moving gas, unlike ...
