- Designing the measurement cell of a swept-field differential aspiration condenser A.A. Solis E. Sacristán Física, Astronomía y Matemáticas ionization spectrometry gas monitoring ionic mobility Tammet transform We present the description of a small-size and low-cost sensor based on the aspiration method that can be used as an ion-mobility spectrometer:the planar swept-field first-order differential aspiration condenser. A mathematical model for the measurement cell of the condenser hasbeen developed, and in this paper a design strategy based on the model is described. A measurement cell has been constructed following thisstrategy and was used in a prototype aspiration condenser device. Some collector-plate ion-current curves have been measured for gas sampleswith several different anesthetic gases in different concentrations in order to evaluate the model and the design of the measurement cell.The inverse transform via the truncated singular value decomposition (TSVD) has been applied to the data to obtain ion-mobility spectra.The results suggest that, although the model simplifies the actual physical behavior of the ions, thereby causing some inconsistencies in themobility spectra, it is still useful in the aspiration condensers design process. The proposed device is an attractive small-size, cost-effectivealternative for ion-mobility gas analysis applications. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065204 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
