Abstract
Disclosed are a laser ablation system and method for determining the presence of trace elements in liquid samples such as oils, and/or in powder samples. A sample containing microporous membrane is utilized to prevent 'splashing', 'splattering' and/or 'scattering' of liquid and/or powder sample when laser contained sample effectively 'nebulizing' energy is applied. The present invention is typically used in combination with an inductively coupled plasma and a detector system, such as an Atomic Emission Spectrometer or Mass Spectrometer.
