Note: All Sprint protein
methods are created in the
CEM Corporation laboratory
by trained laboratory
personnel. If a sample
produces incorrect protein
values, a bias (correction
factor) can be entered to
assist in obtaining proper
results.
To obtain a bias, test the
sample by both an AOAC
approved method and
the CEM Sprint method.
Perform at least 5 or more
tests to check repeatability.
Average the results of the
fi ve tests by each method.
Subtract the average of
the Sprint results from
the average of the AOAC
approved method. Enter
the resulting number as the
bias.
Bias = Sprint Avg. - AOAC
avg.
9. Use the “right”
arrow key to select
“Edit.”Press the “Enter”
key.
10. Use the arrow keys and
the “Enter” key to select
and enter the desired
bias. Once the bias
is entered, press the
“Accept” key to store
the bias for the method
in memory.
