- Perform pressure testing of microspheres.
- Run X-ray diffraction on a plain safflower oil sample, a plain PVA MW 130 sample, and a PVA 146 microsphere sample that ended up becoming a hydrogel.
- Finish running DSC on a Rhodamine 6G sample(this was unable to be run last time due to lack of gas).
- The general protocol for pressure testing described on 2013/04/17 was followed.
Figure 1. Pressure testing of prepared microspheres.
- Use a Kimwipe and acetone to thoroughly clean the low background sample holder
- Insert Sample into the low background holder. Note: Must make sure that the sample is completely flat and that the particle sample size is very small. If the sample is too large, use a mortar and pestle to completely grind the sample
- Turn on the chiller
- Turn on Miniflex II. This is the white button on the machine
- Turn on X-ray. The machine will be on when the red lights on the button labeled x-ray light up
- Using a Geiger counter, test the radiation from the machine
- Set sample in sample holder and record sample holder number
- Close the door to the x-ray
- Open software on computer
- The samples will be posted when received.
