Do you have a question about the Malvern Mastersizer S Series and is the answer not in the manual?

Summary

How the Mastersizer Works

How Does the Mastersizer Do It?

Details the two procedures: capturing scattering patterns and analyzing data via presentation.

How to Make a Measurement

Guides users through the practical steps of setting up, aligning, and measuring a sample.

How to Analyse the Measurement Data

Explains the three steps for analysis: choosing model, presentation, and calculating the result.

Making a Measurement

Sample Preparation

Emphasizes the critical importance of sample preparation for accurate measurements.

Choosing a Range Lens

Guides selection of the appropriate range lens based on sample size and dispersion method.

Sample Dispersion Method

Discusses lens suitability for different sample dispersion methods (air vs. liquid).

Always Measure a Background

Explains the importance of background measurement for subtracting ambient light.

Instrument Preparation

Covers system checks, lens fitting, and beam expander setup before measurement.

Align the System

Explains how to align the laser centrally on the detector for accurate measurements.

Take a Background Measurement

Describes the procedure for taking a background measurement to subtract noise and contaminants.

Add the Sample

Guides on adding sample to achieve correct concentration and monitoring obscuration.

Measure the Sample

Details the final step of performing the sample measurement to obtain scattering data.

Analysing the Measurement Data

Choosing the Correct Analysis Mode

Explains the different analysis models (polydisperse, multimodal, etc.) and their usage.

Choosing the Correct Presentation

Discusses selecting presentations based on sample optical characteristics and the Malvern grid.

Calculating the Result

Explains how to initiate the calculation and interpret the residual for fit quality.

Viewing and Printing the Results

Interpreting the Results

Results are Volume Based

Clarifies that the primary size distribution derived is volume-based, not number-based.

Equivalent Spheres

Explains how irregular particles are represented as equivalent spheres for size measurement.

Derived Distribution Parameters

Details parameters like D[m,n] and span calculated from the fundamental distribution.

Understanding the Tables and Graphs

Explains the meaning of common terms and values in results tables and graphs.

Automating the Process

Setting Up a Sequence

Guides on configuring measurement procedures, number of measurements, and delays.

Process Sequence Setup

Details options for analyzing data, saving results, and performing statistical calculations within a sequence.

Sample Preparation

Representative Sampling

Emphasizes ensuring the sample taken is representative of the whole batch.

Considerations for Dry Samples

Discusses factors for analyzing dry samples, including flow characteristics and cohesion.

Considerations for Wet Samples

Highlights considerations for wet samples, focusing on dispersant choice and preparation.

Choice and Preparation of the Dispersant

Guides on selecting and preparing the suspension medium (dispersant) for wet samples.

Advanced Result Processing

Modifying Results

Explains ways to modify analysis results, controlled via Setup-Result Modifications.

Killing Channels

Details removing data or result channels to exclude noise or contaminants.

Kill Data

Describes removing data channels to limit effects of bubbles, contaminants, or spray issues.

Killing Result Channels

Explains removing result channels to isolate modes or isolate expected distribution characteristics.

Shape Correction - Changing the Size Calibration

Explains how to modify Mastersizer results to match other sizing methods.

Transforming Result Type

Explains converting volume distribution results to surface area, length, or number distributions.

Maintenance

Cleaning the Optics

Explains how to clean cell windows, range lenses, and the beam expander.

Cleaning the Cell Windows

Details the procedure for removing, cleaning, and replacing cell windows and O-rings.

Advice for Continuous Sprays
