| Zusammenfassung |
| The Russian spacecraft Luna-Resurs will be landing on the lunar south pole in 2019. One of
the scientific instruments on board the spacecraft is the gas chromatographic mass
spectrometric complex (GC-MS), dedicated to analyse the volatiles in the lunar
soil.
For this instrument we combined our compact time-of-flight mass spectrometer (TOF-MS)
with a chemical pre-separation of the species by gas chromatography (GC). Coupled
measurements with both instruments were successfully performed with the prototype
of the mass spectrometer and a flight-like gas chromatograph. The system was
tested with two test gas mixtures, a mixture of hydrocarbons and a mixture of noble
gases. Due to its capability to record mass spectra over the full mass range at once
with high sensitivity and a dynamic range of up to 106 within 1 s, the TOF-MS
system is a valuable extension of the GC analytical system. The prototype of the
combined GC-MS complex is able to detect concentrations of volatile species in the soil
sample of about 2 -
10-10 by mass for hydrocarbons and 2 -
10-9 by mass for noble
gases. |
