Sample Spinner Option for the BTX II & TERRA

The Olympus TERRA and BTX-II XRD instruments have an optional sample chamber that spins rather than vibrates.

This is useful for a variety of applications: •  The spinner cell can be used when testing some slurries

and gels. It has also been used for some solids that are not in powdered form.

•  The sealed spinner cells are especially useful in testing volatiles, hazardous substances, or air-sensitive materials

•  The spinner cells can be labeled and archived for future reference which is especially useful for possible litigation

Assembly

Step 1: Gather materials to prepare your sample cell

Sample Spinner Assembly

Micro Spatula

Quartz standard

Sample Cell Top Window

Sample Cell Bottom Window

Step 2: Loading the Sample •  Using a micro-spatula, place enough sample to cover the window on the bottom

sample plate. •  Using the spatula or a straight edge, smooth out the sample inside the spacer

release liner – do not overfill as just a thin film is needed to cover the window.

Step 3: Preparing the sample cell

•  Remove the release liner by grabbing the tab and pulling away from the sample plate to reveal the adhesive spacer.

•  Align the label of the top window to cover the sample. Press firmly to seal. •  The sample can be named and archived as a representative sample for future use.

Step 4: Loading the Sample •  Place the sample cell with the label window facing up inside the spinner

assembly and screw in (finger-tighten) the sample locking back of the sample spinner holder.

•  Insert the sample spinner assembly into the TERRA or BTX-II

Step 5: Create a spinner mode on your TERRA or BTX-II If your instrument did not come originally equipped with the spinner assembly you will need to set up the spinner mode. Navigate to the Settings tab on the user interface and click on the “Add New Mode” button on the right side of the screen.

Step 6: Adjust your default settings

•  Name this new mode “Spinner” and scroll down the list to change the Piezo parameters. To change parameters, unclick the defaults check box and enter new values for the high and low Piezo Frequency and Piezo Volume as shown below.

Step 7: Create a Set

Scroll to the bottom of the list and click “Create Set.” This will close the active window and add your new Spinner mode to the list of modes at the start of an acquisition.

Step 8: Start a New Sample

To use the sample spinner, ensure that the Spinner mode is selected from the pull down menu at the start of an acquisition. If adding this mode after you have purchased the instrument you will need to re-calibrate with a quartz standard using the spinner before running your samples.
