Abstract
Systems and methods are provided for analysis and/or profiling of petroleum samples. The systems and methods allow for compositional analysis of samples using techniques that can be implemented outside of a laboratory setting, such as in a refinery or even at a petroleum or hydrocarbon source. The techniques are enabled by using desorption electrospray ionization as a method for generating ions for detection by mass spectroscopy. Desorption electrospray ionization can be used to generate ions for detection from a liquid or solid petroleum (or other hydrocarbon) sample with minimal sample preparation. For solid samples, the technique can also be used to identify changes in composition of a petroleum sample relative to a dimension of the solid sample.
