Figure 1
(a) Plots showing the equilibrium RH for salt solutions commonly used as precipitants or additives in macromolecular crystallogenesis measured using the HC-Lab. (b) The measured vapour pressures above solutions of ammonium sulfate (Wishaw & Stokes, 1954BB41) and sodium chloride (Robinson, 1945BB30). The lines show the calculated RH from Raoult's law (Wheeler et al., 2012BB40). The measurements made using the HC-Lab [panel (a)] more accurately reflect the predicted values from Raoult's law.
