Ninhydrin Test for Soil Testing

Purpose:
The purpose of the ninhydrin test is to determine the presence of amines or α-amino acids in a given sample. This is applicable to the science mechanism of the rover because the presence of these amines or α-amino acids can indicate the presence of extant life within a soil sample.

Interpreting Results:
After the initial experiment is conducted, the samples must be observed for colour changes. If a yellow-orange colour develops, this indicates hydroxyproline and proline in the sample. Blue-Purple indicates ammonia, primary/secondary amines, and/or amino acids in the sample. A brown colour indicates
