The efficient and simple way to obtain reliable particle analysis

An unbeatable combination: determining particle sizes as per ISO 13320 with the robust PSA series and Kalliope software.

Anton Paar GmbH

TPSA by Anton Paar can be operated with a sample changer for liquid dis-persions and dry powders.

Results from Anton Paar for BAM ring test 2019. The PSA series with Kalli-ope software achieved the maximum points total.

Particle size distributions can be resolved best by improved calibration processes. This is of particular significance when measuring powder mixtures. Measured with a PSA device from Anton Paar (dispersed in water, analysis as per Mie).

Determine particle sizes at the highest level

Particle size is a decisive parameter for product quality wherever powder or dispersions are produced or processed. Many companies rely on a quick and robust method for this: laser diffraction.

The 2019 ring test for determining particle sizes was passed with a score of 100 %

How well measuring devices perform is assessed by means of independent ring tests as well as validation with certified standards. This year's ring test, RV BAM-5.5-2019, was undertaken by the Federal Institute for Material Research and Testing (Bundesanstalt für Materialforschung und -prüfung, or BAM) with three powder samples and 43 participants worldwide.

The recorded D-values (e.g. D90 means 90 % of the sample volume forms particles with a smaller diameter than this value) of the samples were evaluated for the analysis with regards to a defined tolerance range. Anton Paar fulfilled all 9 criteria and subsequently passed the test with a score of 100 % (see image gallery).

Optimized sensitivity and resolution

Key factors for many users are the comparability between different devices and outstanding reproducibility, time-efficient measurements thanks to an increased automation level and fast support. These factors are what the tried-and-tested hardware of the PSA series and the new Kalliope software by Anton Paar have in common.

PSA laser diffraction instruments are aligned with calibration standards in order to achieve good comparability and high reproducibility. With Kalliope, Anton Paar has improved both comparability and the calibration process, and combined these with more efficient use of established algorithms. This means that small fine portions are detected more efficiently, and the resolution of widely distributed powder mixtures is increased.

The image gallery shows the particle size distribution of various quartz powders, and a measurement of mixtures of these. The result shows that both the very fine particle fraction (quartz powder 1), and the rough portion of 'quartz powder 3' are resolved efficiently.

Intelligent software & automation

As well as incorporated databases for methods, solvents, and materials, Kalliope also offers full 21 CFR Part 11 conformity and streamlining, such as the intelligent automatic selection of input parameters. The hardware can also be automated with a sample changer.  This can pre-disperse the samples and prioritize urgent samples. This means that resources can be saved and user errors reduced.
