Other values recorded include ammonia, chlorine, water hardness (calcium and magnesium), dissolved oxygen and organic carbon.
It might also boast signs of organic carbon, thought to be one of the building blocks of life.

Lehmann, the lead author of the paper which is published in the journal Nature Geosciences, said that the black carbon content of soils in the study ranged from zero to 82 percent of soil organic carbon.
But what Curiosity can do is characterise any organic (carbon-rich) chemistry that may be present.
These are known generically as inorganic nanotubes, reflecting the distinction in chemists' minds between organic (ie, carbon-based) molecules, and all the others.
Because it uses organic materials, any carbon dioxide released during the generation of energy is offset by that absorbed during the plant's life, so the process as a whole is broadly balanced, or "carbon neutral".
Soil samples from around the stone's socket will be analysed and any organic material found radio-carbon dated if possible.
An explosives expert told CNN the yellowness of the flame probably came from carbon or some organic fuel such as sugar that contains it.
In some locations, sedimentation created sufficient pressure to convert -- to cook -- the unoxidized carbon in the organic material into oil, some of which was trapped in reservoirs.
In a briefing, Nasa scientists announced that Curiosity had detected organic compounds - complex molecules containing carbon, without which no known life can develop.
And going through the hyper-rational process fits in well with other cultural artifacts of medicine like memorizing a thousand carbon molecules to pass organic chemistry or spending six months studying for the MCATs.

Some kind of organic metallic alloy stronger than titanium or carbon steel, harder than diamonds.
These include the exhaust gases such as nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), and carbon monoxide (CO).
When heating up a chlorine compound with other Martian soils, Curiosity discovered that the compound reacted with carbon to form a simple organic.
UTC's solution: Pass the return air through an aluminum filter sprayed with titanium dioxide that, hit with ultraviolet rays, sets off a chemical reaction that breaks down nasty organic compounds like benzene and formaldehyde into carbon dioxide and water.
It is from a class known as the carbonaceous chondrites - primitive, carbon-rich meteorites that contain organic compounds such as amino acids.
There was even speculation about a dark material on the tiny planet that could conceivably contain the same organic molecules being hunted on Mars, the carbon-based building blocks that are essential to all life.
During photosynthesis -- the process when the plant absorbs carbon dioxide and gives off oxygen -- organic tissue absorbs airborne toxins.
Both involve heating organic materials in a vacuum until they break down into carbon and vapors that can be condensed into a low-grade fuel oil.
In the past year, for example, Dr Seddon and Tom Welton, a chemist at Imperial College London, have shown that one of the most important and difficult processes in industrial organic chemistry, the Diels-Alder reaction (which links carbon atoms together and thus allows big molecules to be assembled) can work better in ionic than in conventional solvents.
This is because the degree of carbonisation of organic material as measured with electron spin resonance is dependent only upon the amount of carbon and not on the time material has been heated for.

One key element in searching for life on Mars is the presence of methane in the Martian atmosphere As a simple carbon compound, methane is often a precursor to the formation of the complex organic chemicals that make life possible.

The Naite even includes an Ecomate application with Carbon Footprint Calculator that shows how much CO2 you're saving while walking your fields of organic tie-dye ink.
