... Spectrometry, isothermal, wet-needle injection, gas-tight syringe, extraction, hydrocarbon ladder standard, carbon strip, substrate, ignitable liquid Gas Chromatography-Mass Spectrometry (GCMS) is an analytical method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample. Gas Chromatography is used for separating components in a mixture, and ... Mass Spectrometer is used in the qualitative and quantitative analysis of each component that was separated by the GC. The combination of these two highly applicabl...

... the contents through a filter, the liquid organic layer was separated from the solid insoluble layer. The resulting liquid organic layer is set aside to be tested. The resulting solid insoluble component is put through a similar process, only this time, instead of ethyl acetate, distilled water is used. The distilled water is a polar solvent, so it will be able to extract and ... it is highly likely that the two organic compounds in our unknown soil sample is m-nitroaniline and naphthalene. Since we believed that our soil had naphthalene and m-nitroaniline, we created a method to separa...
