“…The transparency measurement technology provides the smallest value of MSZW, which is believed to be the most accurate measurement technology among the three technologies (Kubota, 2008). Kadam et al (2012) observed that the MSZW was not a reproducible point at small volumes but was a spread that roughly increased inversely proportional to the volume in their experiments. Many literature studies reported the development of the analysis theory and technology of MSZW on increasing the measuring accuracy in recent years (Chaitanya and Sarkar, 2014;Peng et al, 2014;Sangwal et al, 2014).…”

“…Thirdly, the volume of the crystallizer and the stirring rate also had great influence on MSZW. It has been stated that the MSZW is not a reproducible point at small volumes but a spread which increases roughly inversely proportional to the volume (Kadam et al, 2012). In addition, MSZW is influenced by the detection method and sensitivity.…”

L-arabinose is widely used in food, medicine, chemistry, and biology fields; however, solubility and seeded metastable zone width (MSZW) of L-arabinose have not been reported in the literature. In this paper, solubility and MSZW of L-arabinose in aqueous solution were determined. Solubility of L-arabinose was measured in the range of 20-68 °C by a conventional equilibrium solubility method and quantitation was determined using the ion chromatography technique. Seeded MSZW was determined in the range of 51-73% by the calorimetric method. The effect of two salts (potassium chloride and calcium chloride) on the solubility and MSZW of L-arabinose were also evaluated. Results showed that both potassium chloride and calcium chloride increased the solubility of L-arabinose, and this increase was intensified with temperature rise. The MSZW of L-arabinose was not constant but a spread. Potassium chloride increased the MSZW of L-arabinose. However, the effect of calcium chloride on MSZW of L-arabinose was concentration dependent. Conclusion: the L-arabinose solubility increased with the increase in temperature, and both potassium chloride and calcium chloride increased the solubility of L-arabinose in aqueous solution. The seeded MSZW of L-arabinose is not a constant; it increases in the presence of potassium chloride and varies with the change in calcium chloride concentration.

Abstract. There has been much recent interest in the role of solution chemistry and in particular the importance of molecular self-assembly in the nucleation of crystalline phases.Techniques such as FTIR and NMR have highlighted the existence of solution phase dimers which in many cases mirror the structural synthons found in the resulting macroscopic crystals. However there are no reported examples in which this new insight into the solution phase has been linked directly to the kinetics of crystal nucleation. Here for the first time, using a combination of solution FTIR, computational chemistry and measured crystal nucleation rate data, such a link is demonstrated for p-aminobenzoic (PABA) and benzoic acids nucleating from polar and nonpolar solvents. Solute dimerization and desolvation are found to be rate determining processes in the overall nucleation pathway.
