New PDF release: Differential Ion Mobility Spectrometry: Nonlinear Ion

By Alexandre A. Shvartsburg

ISBN-10: 1420051067

ISBN-13: 9781420051063

Over the decade, medical and engineering pursuits were transferring from traditional ion mobility spectrometry (IMS) to box uneven waveform ion mobility spectrometry (FAIMS). Differential Ion Mobility Spectrometry: Nonlinear Ion delivery and basics of FAIMS explores this new analytical know-how that separates and characterizes ions by way of the adaptation among their mobility in gases at low and high electrical fields. It additionally covers the unconventional issues of higher-order differential IMS and IMS with alignment of dipole direction.

The publication relates the basics of FAIMS and different nonlinear IMS ways to the physics of gas-phase ion delivery. It starts with the fundamentals of ion diffusion and mobility in gases, protecting the most attributes of traditional IMS which are correct to all IMS ways. development in this starting place, the writer reports various high-field shipping phenomena that underlie differential IMS. He discusses the conceptual implementation and first-principles optimization of FAIMS as a filtering method, emphasizing the dependence of FAIMS functionality metrics on instrumental parameters and houses of ion species. He additionally explores ion reactions in FAIMS brought on by box heating and the results of inhomogeneous electrical box in curved FAIMS gaps.

Written through an entire scientist within the box, this cutting-edge ebook provides the basis to appreciate the hot know-how of nonlinear IMS methods.
