The influence of mineralogy on recovering organic acids from Mars analogue materials using the “one-pot” derivatization experiment on the Sample Analysis at Mars (SAM) instrument suite

► The search for organics on Mars is important to find the existence of a biological activity. ► This search will require a chemical extraction and derivatization step. ► We have developed a one-pot extraction using MTBSTFA and DMF for the SAM experiment on MSL. ► MTBSTFA-DMF extraction of martian analogs materials facilitated the detection of organics.
