This guide outlines the steps you need to take to set up your Archimedes Resonant Mass Measurement system.
Preparing Standard Solutions
• Ensure all vials to be attached to the Archimedes instrument are polymer-coated (Order RMM0005 from Malvern Panalytical Helpdesk for a box of 24 or contact your local Malvern Panalytical representative). These polymer-coated vials have a mottled polymer coating rather than a clear finish and provide enhanced user safety in the unlikely event of a latent defect in the vial causing a breakage.
• Before use, clean all vials with glass cleaning detergent, ensuring to remove all residue with ultra-pure water. Leave vials upside-down to prevent dust settling inside the vials while drying.
• Ensure liquid-containing vials are only filled to three quarters of their capacity.
|Solution Required||Part Number||Function||Preparation Procedure|
|Standard for Micro Sensors (Serial Number: A----H)||RMM0003||Size calibration of Micro sensors||Sonicate and dilute ~1 µm polystyrene latex in ultra-pure water to approximately 107 particles/ml|
|Standard for Nano Sensors (Serial Number: D----E)||RMM0004||Size calibration of Nano sensors||Sonicate and dilute ~500 nm polystyrene latex in ultra-pure water to approximately 108 particles/ml|
|100% D2O||RMM0008||Calculation of instrument bulk sensitivity||Ensure vial is completely dry before adding D2O|
|Reference Solution||RMM0011||Sneeze profile visualization||Dilute 1ml of 100% D2O in 14ml of ultra-pure water|
Waste vials should be empty
Setting up the Vials
Screw vials into the vial ports as indicated in Figure 1.
