MassWorks is a computer software that allows for the recognition of a PFTBA tune gas within a GC-MS sample run. From this one can obtain an accurate mass calibration and apply this calibration to any desired sample. This calibration allows for the calculation of the high-resolution molecular weight and isotope ratio determination for the sample under experimentation. This software was installed onto an Agilent Intuvo Single Quadruple 5977B Gas Chromatograph Mass Spectrometer. The technique of solid phase microextraction (SPME) was utilized for the sampling of bakery products. SPME is an extraction sampling technique that utilizes a polymer coated fiber with an extraction phase to absorb volatile organic compounds. After extraction, the polymer coated fiber is directly injected within the injection port of the gas-chromatograph mass spectrometer (GC-MS). SPME GC-MS is suitable for analyzing small volatile organic molecules because of the lack of solvent interferences and minimal sample preparation. This allows for the accurate analysis of bakery products. In this presentation, cinnamaldehyde and vanillin were quantified utilizing the technique of SPME GC-MS within homemade chocolate chip cookies. In addition, the high-resolution molecular weights were calculated, and the isotope ratios were identified utilizing the MassWorks software.
