Short summary
The first set of studies illustrates that the liquid/liquid phase separation relative humidity (SRH) does not depend strongly on molecular weight. The second set of studies shows that for most particle types and temperature range studied, SRH does not depend strongly on temperature. SRH did depend strongly on temperature for particles containing α,4-dihydroxy-3-methoxybenzeneacetic acid mixed with ammonium bisulfate due to a combination of low temperature and low water content.
The first set of studies illustrates that the liquid/liquid phase separation relative humidity...
