With a total of 180 samples from both Ghana and the Belgium markets, 10 g was weighed from each sample into a 50 mL tube using the Sartorius analytical balance.
The details are given in table 8. Putting values in above from table 8 the combined uncertainty due to HVS; The analytical balance used is Mettler Tolledo AX 204 with accuracy ± 0.1 mg.
(4) After the core slug cooled down, the sample was suspended on the analytical balance.
The analytical balance (BT 124S) was from Sartorius.
The analytical balance has a scale capable of measuring within 0.001 g.
In addition, to analyze coupon weight loss coupon surfaces were cleaned (washed in acid, neutralized with sodium bicarbonate, rinsed in water and acetone, and dried in an air stream) and coupon weight loss was determined by measuring the weight of the coupon using an analytical balance (Sartorius AG model TE214S, Goettingen, Germany) as previously described (Marques et al. 2012).
Each tooth was coated using a separate microbrush, which was dipped in the DSF and weighed before and after the application using an analytical balance (Model S2000, Kern & Sohn GmbH, Balingen, Germany).
The weight, the hardness, and the thickness of the tablets were measured using an analytical balance (model M-220, Denver Instruments, USA), hardness tester (Dr. Schleuniger 8M, from Pharmatron/Sotax, Switzerland), and a digital thickness gauge (number 093, Mitutoyo, USA), respectively.
