Abstract. Polar ice contains chemical impurities, which can be used as a proxy for the past climate, using state-of-the-art chemical methods. Despite its capability to access critical physicochemical parameters of insoluble particles, such as number concentration, mass and size distribution, and elemental composition, single particle inductively coupled plasma-time of flight mass spectrometry (SP ICP-TOFMS) has yet to be fully utilised to study polar ice. We demonstrate the largely qualitative S
