1. A method, comprising:
conveying a downhole tool in a borehole penetrating a subterranean formation; obtaining, using the downhole tool while the downhole tool is positioned downhole, a mass spectrum of a sample subject to a combined chemical and electron ionization process; and determining a concentration of a component of the sample by utilizing a chemical and electron ionization model and the obtained mass spectrum. |
