Improvement of Ammonium Sulfate Crystal habit by Admixtures.

Role of solvents in improvement of dissolution rate of drugs: crystal habit and crystal agglomeration.

Crystallization is often used for manufacturing drug substances. Advances of crystallization have achieved control over drug identity and purity, but control over the physical form remains poor. This review discusses the influence of solvents used in crystallization process on crystal habit and agglomeration of crystals with potential implication for dissolution. According to literature it has ...

Getting the improvement habit

To cite: Lucas B. BMJ Qual Saf 2016;25:400–403. Improving healthcare services can all too easily become synonymous with the use of certain in vogue tools for improving quality. Trigger tools, run charts and driver diagrams are just three examples of techniques used by frontline staff who are undertaking improvement work. Educators seeking to teach improvement are similarly faced with long lists...

Isolation of urinary 17-ketosteroid conjugates by ammonium sulfate precipitation.

Ammonium sulfate precipitation of urinary 17-ketosteroid conjugates is a rapid, effective method for isolating and purifying them. Negligible quantities of pigment are produced during acid hydrolysis of solutions of the precipitated conjugates. Despite elimination of nonspecific chromogenic material, colorimetric determinations of Zimmerman chromogens with use of the Allen correction of absorba...
