Why conditions make your job easier
The intelligent Titrator
The DL70 family of titrators do more than just automate the titration process. They are able to make decisions as to what should be done next, what sequence should the steps in the method follow, and even whether a result is within specifications or not. What should the operator do if a result is outside specifications? Report the violation to his supervisor, repeat the analysis, or even make some changes in the production process. These are just some examples of typical messages the instrument could display when a result is outside specifications.
How is this possible with an automatic titrator?
The answer lies in the way a DL70 method is made up of individual tasks the titrator should perform, for example, STIR, DISPENSE, TITRATION, CALCULATION, REPORT, to name a few. For almost all of these functions a condition can be attached which must be satisfied before the task should be performed. Does it make sense to perform a calculation and report a result even when no equivalence point was detected? One of the functions or tasks the titrator is capable of is to display an instruction for the user. This so called instruction can also have a condition attached to it so that it will only bedisplayed if the condition is met. This condition could be, for example, that the sample has a certain pH, the result of a titration is outside a certain range, the sample is too hot or too cold or numerous other possibilities.
The possibility of having these if...then... conditions in the DL70 family makes it the intelligent titrator of choice!

Typical use of this decision making ability:
An analyst wants to determine the acidity or basicity of a sample but has no idea whether the sample is in fact acidic or basic. No problem for the DL70 family. When analysing the sample the first thing the instrument does is measure the sample pH. Based on this result the titrator decides whether to titrate with an acid or a base and automatically selects the appropriate titrant and proceeds to titrate. At the end of the titration the titrator then decides whether it should calculate the result as acidity or basicity and reports the result. Its as simple as that.
