Reported amount (mg/g) =
where
is the mean of the triplicate values;
t
,
is the
t
critical value; and
is the size of the
standard error [ =
s/
√n, where
s
is the standard deviation and
n
is the number of replicates].
For triplicate measurements and α=0.05,
t
critical value is 4.303.
H. Typical Chromatograms
Typical chromatograms are shown in Figure
2016.16
for (a) a mixed calibration standard
solution and (b) a turmeric rhizome sample.
