The GC/MS experiment was designed to detect organic compounds, which are the fundamental keys of life. In this process, Martian soil samples were heated to vaporize any organic …

However, some scientists haven’t been satisfied with the conclusion and have questioned the ability of the Viking GC/MS to detect organic ma-terial. The questioning finally snowballed this …

It was intended to detect evidence of bological material in the Martian soil. It took a small soil sample, separated volatile elements using a gas chromatograph, and analyzed their …

Conducting gas chromatography and mass spectrometry in the laboratory was hard enough. In the early 1970s, building such an instrument as even a lab model required experts who could …

The Gas Chromatograph/Mass Spectrometer (GCMS) instrument was designed for NASA's Viking Martian lander. It analyzed Martian soil, pyrolyzing samples in search of organic content.

Diagram and photo of the GCMS and associated equipment. The Viking gas chromatograph-mass spectrometer (GC-MS) was a device carried aboard each of the Viking spacecraft landers in …

Over the past decade, reports occasionally appeared suggesting that the Viking GCMS experiment may not have been able to detect certain organic compounds or low levels of …

Jun 1, 1978 · The Mars viking gas chromatograph–mass spectrometer is described. The system is designed to determine the composition of the Martian atmosphere and detect and identify …

To rebut this assertion, the Viking experiment, test data, and results on Mars are reviewed, and the fallacies in the design, execution, and interpretation of the new experiments presented by …

Jan 1, 2004 · With these methods, the detection limit for amino acids, carboxylic acids and nucleobases is several orders of magnitude more sensitive than the Viking GCMS instruments …
