Malvern also informs us that its new Version 2 software for the Mastersizer 2000 particle size analyser is now available. This introduces powerful post-measurement features and new controls and facilities for the measurement itself.

New post-measurement features include a result emulation utility that allows emulation of results from other techniques. A graph zoom enables detailed examination of critical areas of the distribution curve, and a "cut and paste" facility simplifies the transfer of graphs and tables into other software packages. The new configurable records page allows the operator to display a wide range of key measurement parameters, making them available at a glance. This is believed to be an effective way of highlighting differences or identifying "out of specification" material in a production run. All records are numbered and, to comply with good laboratory practice (GLP), there is no renumbering of records following any deletions, so that all deletions are obvious. For extra security, layered access ensures that deletion and other sensitive activities can be confined to authorised users only.

Included in the new measurement utilities is more precise control of ultrasonication in standard operating procedures (SOPs). Also, a new mode of operation called Variflow which reportedly allows better measurement of disk-shaped particles from within a SOP. Measurement of pigments and inks is said to have been further refined by giving the user the ability to input separate refractive indices for both the helium neon red laser and the blue light used to give greater sub-micron resolution.
