SDCalc FAQ

This page contains answers to common questions, along with some tips and tricks that we have found useful and presented here as questions.

  1. How do I bracket a calibration set?
  2. What is check standard bracketing?
  3. What is point bracket bracketing?
  4. Do I need to dilute the sample volume on a related compound sample?

How do I bracket a calibration set?
  1. Use the default calibration set to calculation the average of 5 using the "Basic" calibration method. 
  2. Then create a new calibration set by pressing Alt+Ins keys.
  3. Select "Point  Bracket" from calibration method in the new set.
  4. Then select the "Bracket With" combo box and select the first calibration set (Avg. of 5).
  5. The group list box on the right will start to show the bracket groupings.  To make the box update use the "Next" navigator key or press the Alt+PgDn keys.

What is check standard bracketing?

Check standard bracketing takes the average response from the calibration pair and averages the bracket averages.  The percent difference check and system use the average as well.  If a calibration set has only one response that response is used instead of the average.

What is point bracket bracketing?

Point bracket bracketing takes the last response from the first calibration pair and the first reponse from the second calibration pair.  The percent difference check and system use these same response values in their calculations.

Do I need to dilute the sample volume on a related compound sample??

No you don't.  On the old GenevaCalc program version 1.0 you did need to do the dilution.  For example, If the method called for 25.00ml as the sample concentration you would format the concentration as 1/25 to get 0.04.  In the new related compound test method just use the 25.00ml in the dilution field.
