ZETASIZER MANUAL DOWNLOAD

The zeta potential SOP editor menu is: To ensure reliable and accurate measurements proper sample preparation is extremely important. We mentioned earlier that the speed of particles that are being moved by Brownian motion is related to the size of the particles Stokes-Einstein equation. Page Cell type Select the appropriate cell from the list. Page 62 Chapter 3 Making measurements Once these stages have been completed, the measurement proper will start; again the actual measurement sequence will depend upon the measurement being performed. Page 83 Records and Reports - Viewing the Results Chapter 4 Trend measurements including Aggregation Trend measurements can be viewed using the reports: For normal operations both will be at the default setting.

If the viscosity of the sample is known only at certain temperatures select the Prompt operator to enter viscosity button. The picture above shows the size view. Exporting Results Advanced features Chapter 9 Exporting results The Zetasizer software allows any of the parameters from one or more records, as well as graph and table data to be exported to another application such as Excel, Word or Wordpad.

Print page 1 Print zegasizer pages. Page Chapter 13 Zeta potential theory ions within the boundary move with it, but any ions beyond the boundary do not travel with the particle.

Zetasizer Nano user manual (English)

With Manual selected the measurement will use the user defined settings Shape correction model This option allows selection of the shape correction model used for the measurement. Using a report with a well-plate display Page MAN Sample Preparation Selecting and preparing the measurement cell Malvern offers a range of cells and cuvettes for performing measurements with the Zetasizer system. Enter text from picture: Page 86 Chapter 5 Sample Preparation An important factor in determining the maximum concentration the sample can be measured at, is the size of the particles.

The user also has the ability to create their own custom reports to satisfy their individual needs.

The potential that exists at this boundary is known as the Zeta potential. Page Report designer Chapter 10 The parameter Properties window has the same tabs as the text window, plus a General tab to specify what the parameter is, as shown above: Page 74 Size quality report M This is a summary report detailing whether the result meets the Malvern Instruments quality criteria for a size measurement.

To choose a parameter press the Add button, select the appropriate parameter and press OK. Comments on the reasons for editing can be added and viewed in the report views.

Selecting the Sample - Dispersant window and pressing the button, displays the Dispersants properties manager where these properties can be defined. Page Using SOPs Chapter 8 option applies a scroll down list will be available alongside the parameter.

On the General tab click the Select button. Page MAN There are several ways to export the required information: Page 73 Records and Reports - Viewing the Results Chapter 4 Lower values will be obtained for measurements on weaker scattering sample, or in turbid sample where background scattering is significant.

Please see the size description for details about Temperature, and Cell type. Always quote the following information: Page 21 Introducing the Zetasizer Nano Chapter 2 Using this knowledge and the relationship between diffusion speed and size, the size can be manal. Page Chapter 13 Zeta potential theory position in the cell, however there are a number of reasons for choosing to work at the centre.

Please refer to the manuap in the previous section. The report is divided into four areas; these are described below. For small particles in low dielectric constant media f Ka becomes 1.

Undo and Redo — However, in practice, the properties of the sample itself will set the maximum value. Result Averaging Chapter 9 Advanced features Result averaging What is the average result of a selection of records? Kanual Chapter 8 Using SOPs Size Measurement With the Perform a size measurement check box selected a size measurement will be performed simultaneously with molecular weight.

Page Molecular weight theory Chapter 12 The weight-averaged molecular weight Mw is determined from the intercept at zero concentration i. Page Index Append to file Symbols Aqueous, With Automatic selected, the software will automatically determine the measurement duration.
