| The gas chromatograph separates the substances present, and then each substance is broken into molecular fragments by the mass spectrometer. |
| The spectrometer was modified to incorporate an Oxford cryostat at the sample compartment. |
| The gamma ray spectrometer suite is unique in that it senses the composition below the surface to a depth as great as one meter. |
| Sojourner analyzed the chemical composition of fifteen rocks using its alpha proton X-ray spectrometer. |
| This is a flash artifact and is observed also when the flash is ignited in the empty spectrometer. |
