Phoenix's detection was made by performing chemistry experiments directly on martian soil, and it was made by two different instruments: TEGA, which
heated soil samples and sniffed for released gases, and MECA - WCL, a wet chemistry lab.
In the first run of the Thermal and Evolved - Gas Analyzer (TEGA), described in a press conference, Phoenix
heated a soil sample to 95 degrees Fahrenheit (35 degrees C) and then to 350 degrees F (175 degrees C).
It slowly
heated a soil sample, and then measured the gases released at different temperatures.
