Abstract

This review explores some of the design choices made with single particle mass spectrometers. Different instruments have used various configurations of inlets, particle sizing techniques, ionization lasers, mass spectrometers, and other components. Systematic bias against non‐spherical particles probably exceeds a factor of 2 for all instruments. An ionization laser tradeoff is the relatively poor beam quality and reliability of an excimer laser versus the longer wavelengths and slower response time of an Nd‐YAG laser. Single particle instruments can make special demands on the speed and dynamic range of the mass spectrometers. This review explains some of the choices made for instruments that were developed for different types of measurements in the atmosphere. Some practical design notes are also given from the author's experience with each section of the instrument. Published 2006 Wiley Periodicals, Inc., Mass Spec Rev 26:150–165, 2007

## Abstract A small high‐irradiance laser ionization time‐of‐flight mass spectrometer (LI‐TOFMS) with orthogonal sample introduction was described. High irradiance of 6 × 10^10^ W/cm^2^ at 532 nm from a Nd : YAG laser was applied in the experiment to get a high ionization degree in plasma and to di
