Title: Innovations of Alejandro Casado
Introduction
Alejandro Casado is a notable inventor based in Boecillo, Spain. He has made significant contributions to the field of atmospheric analysis through his innovative patents. With a total of three patents to his name, Casado's work focuses on improving the detection of atmospheric vapors and gas phase ions.
Latest Patents
One of his latest patents is a method for detecting atmospheric vapors at parts per quadrillion (PPQ) concentrations. This invention enhances the detection of atmospheric vapors by ionizing them near ambient pressure and analyzing them as ions. The method achieves the lowest detection limits of parts per quadrillion concentrations through various improvements, including the use of a filter to eliminate intense signals from explosive particles. Additionally, it identifies sources of chemical background and presents solutions for their reduction or elimination. Gains in response time are possible by operating at elevated temperatures, and the use of high boiling point solvents is indicated when the ionizer is an electrospray source. Furthermore, increased selectivity is achieved by operating a differential mobility analyzer (DMA) in series with a mass spectrometer, although achieving PPQ sensitivities requires several enhancements in the DMA system.
Another significant patent is a method and apparatus to accurately discriminate gas phase ions using several filtering devices in tandem. This invention allows for fast and accurate recognition of species contained in trace amounts in complex mixtures, such as ambient air or biological fluids. The method employs one or more differential mobility analyzers and possibly a mass spectrometer, all arranged in series. By operating the two DMAs in different regions of the ion drag versus drift velocity curve, it separates ions based on multiple independently discriminating parameters. This process enables very high discrimination, even with a single stage of mass spectrometric separation.
