An automated droplet freezing assay system to study ice formation activities of soil and biogenic particles at warm temperatures


EMSL Project ID
60841

Abstract

Ice nucleation (IN) efficiency of soil and biogenic particles at warmer temperatures (> -15° C) are least understood leading to poor representation of IN in models. We propose to build an automated droplet freezing assay system to study IN efficiency of these particles at warmer temperatures, which is difficult to simulate with current EMSL chambers (e.g., CFDC, IN-ESEM etc.). The system will be suitable for subsequent multi-modal microscopy and mass spectrometry characterization of particles. This new high-throughput capability will benefit EMSL users from aerosol and biogeochemistry fields by providing freezing characteristics of INPs by augmenting other chambers at EMSL to cover broad environmental temperature conditions (0 to -60°C).
