BOD Analyst for Windows Software

If you seed directly to the bottle, the amount of seed material in each bottle will simply be the
seed quantity. If you seed the blank water, the amount of seed material in each bottle depends on
how much dilution water is in that bottle. Note therefore, that your choice of method will affect
the calculations.
You may, after some time, decide that it would be best to change your seeding method. You can
change the seeding method on the Seed added to: field on the General Setup Form. Furthermore,
because the units for the seed quantity are different for the two methods (ml of seed material in
each bottle vs. ml/L of seed material in dilution water), you must adjust the seed quantity for each
of your seeded samples to reflect the new method.
NOTE: The BOD Analyst software shows only one method of adding seed. Therefore, when you
change the method used for seeding, all previously taken batches will be translated to reflect the
current method. This is for display purposes only and WILL NOT affect your data.
