Laser Ablation Sampling With Low-Power Plasma: A LA-MIP-MS Instrument for Spaceflight. [PDF]

open access: yesRapid Commun Mass Spectrom
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.
