Lunar soil studies are planned on-board the Luna-27 polar landing probe of the scheduled Luna-Recourse mission. A sensor, which is called DLS-L, was designed as an additional analytical unit, integrated into a Gas Chromatography GC-L instrument of a Gas Analytical Package, targeted to study products, pyrolytically evolved from soil samples of a close location near the Lunar probe landing point. Gas Analytical Package for direct study of volatiles in the accessible lunar regolith at the landing site is a complex of three instruments: a TA-L thermal analyzer, a GC-L gas chromatograph, and an NGMS neutral gas mass spectrometer. The DLS-L aims in an independent measurement of pyrolytical output dynamics and integral content of H2O, CO2, and in retrieving of isotopic ratios D/H, O-18/O-1(7)/O-1(6), C-13/C-12 for isotopologues of H2O and CO2. The DLS-L sensor data would help for further understanding of physics and chemistry of the Lunar body, as original data of polar Lunar soil first-ever direct study.
