Ion source with laser triangulation for ambient mass spectrometry of nonplanar samples
31 October 2017
Scientists at IOCB Prague have developed a new ion source for analyzing nonplanar surfaces under open-air conditions using mass spectrometry.
Josef Cvačka and coworkers designed a two-position device where the sample height is measured using laser triangulation, and the target compounds are then analyzed using desorption electrospray ionization or desorption atmospheric pressure photoionization.
Their experiments showed good performance of the ion source, offering rapid and/or high-throughput screening of samples in pharma, food, forensic, or industrial applications.
