Resolution enhancement of field asymmetric waveform ion mobility spectrometry (FAIMS) by ion focusing
BACKGROUND Field Asymmetric Waveform Ion Mobility Spectrometry (FAIMS) is a material analysis technology which develops very fast in recent years. Resolution is an important factor used to estimate the performance of this technology. With greater resolution, it's always easier to separate complex mixtures. RESULTS A method to increase the resolution of FAIMS is put forward which focuses ions ...
متن کاملAutomatic Phase Advancing in a Stand-Alone Switched Reluctance Generator at Different High Speeds for Desired Output Voltage
The switched reluctance motor is a singly excited, doubly salient machine which can be used in generation mode by selecting the proper firing angles of the phases. Due to its robustness, it has the potential and the ability to become one the generators to be used in harsh environment. This paper presents an energy conversion by a Switched Reluctance Generator (SRG) when bifilar converter ci...
متن کاملA High Gain Bipolar Pulse Generator with Low Voltage Input Source
This paper proposes a pulsed power generator which consists of two types of switched-capacitor booster modules. A doubling mode module employed to elevate the input voltage to a specified level and, constant mode module is used to increase the elevated voltage into the finally intended bipolar output voltage. Also, the proposed modular structure does not utilize any switches across the load. Ot...
متن کاملAsymmetric Rectangular Waveform in Stimulation with High Frequency Alternating Current Reduces the Threshold for Neural Conduction Block
Introduction Abnormal neural impulses in the nervous system may lead to various diseases and disabilities. High frequency alternating currents (HFAC) has been used to block the propagation of such impulses and improve the symptoms or disabilities. The technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...
متن کاملWaveform Generator Fundamentals
Test equipment applications require signal stimuli varying from advanced communication signals to the playback of captured real-world analog signals. Signal source instruments generate the signal stimulus that is applied to a device under test (DUT). Consequently, signal sources comprise an important class of test instruments. This article describes applications of an arbitrary waveform generat...
