Abstract

Perchlorate (ClO 4 – ) is found in both Earth and Martian surface environments, yet its formation mechanism remains enigmatic. ClO 4 – isotope composition can help to identify the formation mechanism/source, but the conventional gas-source isotope ratio mass spectrometry (IRMS) method requires micromole or larger sample sizes together with tedious mineral precipitation steps. Here, a capable method for measuring δ 37 Cl, δ 18 O, and Δ 17 O values of trace ClO 4 – (
