6.2.7 CONSUMPTION
This section applies to kinetic methods only.
Item Input Comments
Consumption check Check / No Check Check to enable substrate depletion check; reaction
curve will be checked for a excessive initial substrate
consumption
Limit (Abs/min) -999999 to 999999 Given by the manufactorer (approx. Abs/min of the lin-
erarity limit at the point of interest)
First and second point Check / No Check Check and evaluation is performed between the two
first reading points
Time and first point Check / No Check Check and the evaluation is performed before the read-
ing is started
Time before first (sec) 0 to ... Define the time when the check should take place (rec-
ommendation: incubation < 60 sec set to 15; incubation
> 60 sec set to 30)
Behaviour
Conservative Check / No Check Check and during the reading time the system perform
10 readings
Adaptative Check / No Check Check and the system will automatically increase the to-
tal reaction time and the interval between the readings
if the consumption rate is low to optimze precision and
decrease the total reading interval if the consumption
rate is high to preserve linearity; recommended
Initial absorbance
limit -999999 to 999999 Insert the OD limit; if absorbance is below limit in a de-
creasing reaction or above limit in increasing reaction
the sample will be prediluted
Dilution factor 1 to 120 Insert a dilution factor
