Figure 2
(a) Plots showing the equilibrium RH for PEG solutions commonly used as precipitants or additives in macromolecular crystallogenesis measured using the HC-Lab. (b) The measured vapour pressures above PEG solutions from Sadeghi & Shahebrahimi (2011) and Sadeghi & Ziamajidi (2006). The lines show the calculated RH from Raoult's law modified for polymer solutions (Bowler, Mueller et al., 2015). |
