Introduction

1.Introduction

The DL15 Titrator is the ideal solution for all requirements in the food industry, water/ wastewater analysis, and the chemical industry when all that is needed is an endpoint titration or a pH measurement. The DL15 is mainly used to determine the acid and base content of a sample.

It features easy-to-understand intuitive user guidance so that, for example, pressing the Run button twice starts the method you last ran.

The user can assign three other methods to individual function keys, making methods easy to find and start.

The keys used for the most frequently used manual functions are identified by pictograms. Titrants and sensors can be selected from the instrument’s database.

Alphanumeric input is easily entered by means of a special keypad, just like with a mobile phone. There is no need to connect an external keyboard.

The DL15 calculates the analytical results in predefined units and sends an analysis report to commercially available printers.

—The new titrant appears in the list.

• You can discard the changes you have made by pressing Esc to quit the selection. In this case, the titrant is not stored.

•Determine the titer of the new titrant using the automatic titer determination (Titer key) if you have not already entered it manually. See «5.2.5 Titer determination from the Titrant setup».

•In any case, first change the name of the titrant. Otherwise the changes you made for

the existing titrant will be effective on pressing the Save key, and no new titrant will be stored in the titrator!

5.2.2Modifying a titrant

—Press Setup to open the Setup menu.

—Select «Titrant» using the arrow keys and press OK to confirm. The list of the titrants stored in the titrator appears.

—Select the titrant whose parameters you want to change.

—Press Modify.

—The list of parameters of the selected titrant appears and the individual parameters can be selected and changed.

—Press Save to accept your changes and quit the menu, or press Esc to discard your changes and quit the menu.

All titrants contain the following parameters:

	Setup

Name	The name of the titrant.
Conc. [mol/L]	The concentration of the titrant in [mol/L].
Titer	The titer can be automatically determined using a titer determi-
	nation, or manually entered. If the titer is determined through a
	titer determination, the current date and time are stored.
Minimum	The «Minimum» parameter lets you define the lower limit for the
	range within which the titer must be.
Maximum	The «Maximum» parameter lets you define the upper limit for the
	range within which the titer must be.
Titer	This parameter indicates whether the titer determination was
	automatically determined («Determined») or manually entered
	(«Edited»).
Standard	Here you can select one of the standards defined in the titrator
	to determine the titer of your titrant.
Burette	Using this parameter you can define the burette volume. Pos-
	sible values are 1, 5, 10 and 20 mL.
Charge	With this parameter you can record information about the batch
	from which the titrant originates.
Fill rate [%]	The «Fill rate» indicates how quickly the burette is filled with
	titrant. Filling the burette at the highest rate corresponds to a fill
	rate of 100%, and at the lowest rate to a fill rate of 30%. The
	preset value is 100%
Check after [day]	This value is used to calculate the expiration date for the titrant.
	A period of 0 to 100 days can be defined. If the parameter has
	the value 0, no expiration date is determined.
Expiry	If the value 0 is entered for the «Check after» parameter, no
	expiration date is calculated.
Date	The date of the last titer determination. Each time you store the
	titrant, the date is set to 00-00-0000.
Time	The time of the last titer determination. Each time you store the
	titrant, the time is set to 00:00.

Setup

•If you change the name of a titrant and save your changes, a new titrant is created under the new name.

•If the value for the titer determined by a titer determination or the manually entered value is outside the range defined by «Minimum» and «Maximum», an error message appears and the titer must either be determined or entered again.

•When you use a titrant of higher viscosity, it is advisable to reduce the fill rate in order to prevent air being sucked-in when filling the burette.

•If, at the start of an analysis, the titant has expired (the expiration date has been exceeded), a message appears to draw your attention to this. If you still want to perform the determination, you must confirm the message. In the report, a corresponding line appears that notes that the titrant has expired.

5.2.3Deleting a titrant

—Press Setup to open the Setup menu.

—Select «Titrant» using the arrow keys and press OK to confirm. The list of the titrants stored in the titrator appears.

—Select the titrant you want to delete.

—Press Delete.

—In the dialog that follows, you are asked whether you really want to delete the selected titrant. Confirm deletion by selecting «Yes» and pressing OK, or terminate deletion by selecting «No» and pressing OK to confirm.

•You can only delete titrants that have not been used in a method.

•Titrants referenced by METTLER methods cannot be deleted.

Setup

5.2.4Printing a titrant

—Press Setup to open the Setup menu.

—Select «Titrant» using the arrow keys and press OK to confirm. The list of the titrants stored in the titrator appears.

—Select the titrant whose parameters you want to print.

—Press Print.

—The parameters of the selected titrant are printed on the printer as soon as you confirm by pressing OK.

5.2.5Titer determination from the titrant setup

The accuracy of the results of your analysis depends on the accuracy with which you determine the concentration of your titrant.

When you prepare a titrant, a number of errors can occur that cause the actual concentra-

tion (Cactual) to deviate from the desired concentration (Cnom) of your titrant.

The quotient of the actual concentration of the titrant and its desired concentration is called the titer of the titrant:

t = cactual cnom

In the ideal case, Cactual = Cnom and the titer, t, is 1.

If the concentration of the titrant is too high, t is > 1.

If the concentration of the titrant is too low, t is <1.

The titer enables the titrator to calculate the results of your analyses corresponding to the actual concentration of the titrant used. It is therefore essential for you to accurately determine the actual concentration of the titrant against a reference substance before you first use it.

The titrator can store the corresponding titer as a parameter for every titrant defined in the titrator. As long as the titer for a titrant has not been determined, the default value 1 is used.

You can determine the titer yourself, enter the value for the titrant manually in the Setup menu, or to determine it through automatic titer determination with the titrator.

Before doing this, you should make sure that a suitable standard is already stored in the titrator for the primary standard you want to use. If this is not the case, you must first define a new standard in the instrument. See «5.5.1 Adding a standard».

5.3.5Sensor calibration from the sensor setup menu

Zero point and slope

The calibration parameters of a pH electrode are the zero point pH0 (pH at a potential of 0 mV) and the slope.

The theoretical values of a pH electrode are stored in the titrator:

•Zero point = 7.0 [pH] and

•Slope = -59.16 [mV/pH].

The pH calculation is performed according to the following equation:

pH=pH0+ mV signal slope

The slope is corrected for temperature in the calculation of the pH.

The sensor should be calibrated in order to obtain correct values for your electrode. The theoretical values are then automatically overwritten with the calculated calibration data during the calibration.

If you only calibrate your electrode with one buffer solution, only the electrode zero point is recalculated. (Not possible with the titrator.)

Power ManagementThe devices have a power management system which prevents the titrator from switching off unexpectedlyin the event of a power overload. Tasks which would cause a power overload, because a number of pumps,stirrers and burette drives are already in use, cannot be started at all. A notification brings the start attempt tothe attention of the user. It is advisable, if possible, to connect pumps and stirrers directly to samplechangers or other devices which have their own power supply, such as a TBox, instead of to the titratoritself.
