average recovery

Conclusion: This simple, accurate, and high average recovery method is quite suitable for the determination of ferulic acid in wheat bran.

Incidentally, the average recovery percent would increase slightly with increasing column diameter.

Even in those cases, though, the average recovery time was, at 56 years, within a human lifetime.

Content of Nitrofural was determined by UV spectrophotometer with an average recovery rate of 101. 7%.

The total flavonoids determination for the extracts established, and the average recovery of the method was 98. 54% , RSD was 0. 84%.

Results: the three components of the standards was a good linear relationship with linear range, the average recovery are 98%~103%.

Finally, this method was applied to determine Sudan I in hot chili samples, and the average recovery is 97. 8%.

Average recovery rate of the lovastatin mother liquor is 65 %, and average content of lovastatin is 72%.

The method is accurate with the average recovery of standard addition between 95%~105% and the RSD better than 4. 0%.

Results: The spots of thin-layer chromatography were clear and centred, the average recovery was 95. 85%.

Results: The quality of this preparation was stable. The average recovery was 99. 7%, and RSD was 0. 64%.

Results: The separating degree and the linearity were fine with average recovery of camphor 100. 1%, RSD=0. 56%.

Result: The average recovery of ornidazole and cimifi-dine were 99. 81% and 100. 77% respectivery.

The results shows that only 16% of the repeatable uncertainty of an average recovery rate composes the total uncertainty;
