文摘

Evaluation of arsenic preservation during sampling, storage and speciation analysis in sulphidic, low iron hot springs. Liquid nitrogen freezing and oxygen-­scrubbing sachets in secondary containment prevent arsenic species artefact generation. Separation and quantification of thiomethylated arsenic species requires the use of an Atlantis C18 over an IonPac column.
