6. SAMPLE PREPARATION
Note: Please see Table 1 for weight and loading volume for different product range.
Slurry may be used wherever product heterogeneity is expected.
Slurry: Reconstitute the 25g powder with warm water (~50ºC) to a total weight of 200g. Mix
thoroughly on a horizontal shaker for 15 minutes and then sonicate at 50
0
C for 10 minutes.
Cool to room temperature.
1. Weigh sample / slurry into a 100mL amber glass screw cap bottle. Refer to Table 1.
2. Add 0.15 M sodium phosphate buffer to a volume of 50mL.
3. Swirl gently to mix.
4. Autoclave the sample preparation at 121
0
C for 25 minutes.
