Analysis Note
Specific surface area(according to BET; 5-Pt. measurement): 480 - 540 m²/g
Pore volume(N₂-isotherm): 0.74 - 0.84 ml/g
d 50 (laser diffraction, size distribution):9.7 - 11.7 µm
Layerthickness: 80 - 120 µm
Deviation of layer thickness per plate: ≤ 30 µm
A) Cholesterin test
hRf-values
- cholesterin: 35 - 43
B) Steroid test
- methyltestosterone: 14 - 24
- Reichstein S: 28 - 38- hydrocortisone: 40 - 50
Typical value determined on an activated sheet (120°C, 15 min)
Eluent A) aceton/ water (95/5 v/v)
Eluent B) aceton/ water (60/40 v/v)
C) MS suitability test
- Angiotensin II (signal-to-noiseratio 50ng): ≥ 25
measured with 5000 shots
- Caffeine (signal-to-ratio 5ng): ≥25
