Special Considerations:(Continued)
»
If the dextrose concentration in your sample exceeds the sucrose concentration, the
subtraction of a large dextrose “signal” from a smaller sucrose “signal” may result in
significant errors in the sucrose reading. An alternative method involves using two
different , and appropriate dilutions of the sample to first measure free dextrose, then
treat one sample with invertase and analyze for dextrose liberated from the sucrose.
