Abstract

Ambient ionization methods, when equipped to portable mass spectrometric (MS) instrumentation, allow the rapid, on-site processing of field-generated samples. Such a coupling could allow field practitioners like law enforcement and environmental scientists the capability to quickly screening pertinent samples at their discretion. However, the performance of portable technologies could be affected by environmental conditions, particularly considering that many ambient ionization sources are open air in terms of design. In this work, the performance of a portable MS system featuring a homebuilt paper spray ionization (PSI) sources is determined across a wide range of environmental factors such as ambient temperature, relative humidity, and wind speed/direction.
