PURPOSE This SOP establishes the process for identification and quantitation of Aloe Vera in products by proton NMR spectroscopy. SCOPE This procedure applies to dietary supplements and ingredients that contain Aloe vera. 1.0 PROCEDURES 1.1 Safety and precaution 1.1.1 The instrument possesses very strong magnetization. Even though the instrument is shielded, the stray field still exists and it is important to take precaution when getting near to the instrument. 1.1.2 Ferromagnetic objects or person with the pacemaker should not be getting into the stray zone. Figure 1 illustrates the stray zone and cautions that should take when entering the stray field. 1.1.3 Items such as smart phone, ATM cards, watch, and other electronic devices may get damaged by the magnetic field.
