  • Page 34 4.6.2.1 Linear titration In the case of linear titration, the step size remains identical over the entire titration cycle. Linear titration is often used for complicated or unknown samples. Complicated examples include, for instance, chloride in the trace range (-> very flat curve pattern) or titrations in non-aqueous media. If one would use a dynamic titration control in these cases, this would not yield any benefit.

  • Page 35: Result

    4.6.2.3 End-Point titration The goal of End-Point titration consists in titrating as precisely as possible to an end point given in terms of pH, mV or µA. In the case of pH und mV you can also titrate to two end points. Consumption in the end point will be used as a result.
  • Page 36 One inflection points can be analyzed (Fig. 63). Fig. 63 With «only total consumption» the consumption at the last measured pH/mV value will be used. With «1 EQ» the calculated equivalence points of the titration curve will be used. «Formula» (Fig. 62) offers the following settings (Fig. 64). Fig.

  • Page 45: Titration Parameters

    Titration parameters 4.6.4 The «Titration parameter» submenu is used to determine the actual parameters of the method (Fig. 87 and Fig. 88). Fig. 87 Fig. 88 4.6.4.1 Generally applicable titration parameters Depending on the titration mode (dynamic, linear, End-Point titration), it is possible to enter a variety of parameters.

Fig. 90 «Measuring speed» or drift will determine the span of time after which the measured value will be accepted following a titration step (Fig. 91). Fig. 91 Drift-controlled acceptance of the measured value in terms of mV/min is set by selecting «normal», «fast» or «user-defined»...
  • Page 47 Fig. 92 If normal or fast drift was selected before, the values will be defaulted for user-defined drift. In the present case, for instance, 20 mV for normal drift: (Fig. 93). Fig. 93 Drift-controlled acceptance of the measured value is used in most applications. However, there are applications in which the setting of a fixed holding time for measured value acceptance following the titration step is recommendable.
  • Page 48 After the start of titration, it makes frequently sense to have the sample stirred over a defined period of time, for instance, to allow for the sample to be dissolved. The waiting time to be observed prior to the first addition of titration solution can be set using the <Initial waiting time>...
  • Page 49 4.6.4.3 Linear titration If linear titration control was selected, you have to define the step size (Fig. 97). Fig. 97 Linear step size can be set from 0.0005 to 5.000 ml (Fig. 98) Fig. 98 Linear step width can also be set for End-Point titration (pH, mV and dead stop). In this type of titration, linear step width is used after the first continuous titration stage.
  • Page 50 4.6.4.5 Pretitration If the titration agent consumption is roughly known, you can set a pretitration volume. In this process, a defined volume is dosed (= pretitrated) following the initial waiting time. After the addition of the pretitration volume, another defined span of time is observed as the waiting time before the next titration step is added. The pretitration volume is automatically added to the titration agent consumption.
  • Page 51 Fig. 102 Automatic detection of the equivalence point (EQ) can be switched on and off for linear or dynamic titration (Fig. 103). Fig. 103 If automatic EQ detection is off, titration will continue to the predefined end value in mV or pH or to the maximum ml value, respectively.

    Setting of the «maximum titration volume» (Fig. 105) should always make sense. It also serves as a safety criteria to prevent excessive titration, i.e. a possible overflow of the titration vessel. The maximum titration volume can be set between 1.000 and 999.999 ml: Fig.

    Dosing parameter 4.6.6 The dosing parameters (dosing speed, filling speed and max. dosing/titration volume) are determined for each method (Fig. 108). Fig. 108 This applies to all types of methods such as manual (Fig. 109) and automatic (Fig. 110) titration and dosing Solution Preparation (Fig.

    Fig. 138 Fig. 139 Replacing the titration solution 5.2.2 If titration solutions are to be changed, since differing analysis methods are used, one should first consider whether the time required for frequent changes is not more expensive than the acquisition of another dosing unit. As a principle and in the case of all piston/cylinder- systems, a substitution of the titration solution by another one involves mixing and carry-over processes.

  • Page 79 Maintenance and Care of the Titrator The preservation of the proper functioning of the device requires testing and maintenance work to be performed on a regular basis. Regular inspections are essential prerequisites for the correctness of the volume and the proper functioning. The accuracy of the volume is determined by all chemicals-carrying components (piston, cylinder, valve, titration tip and hoses).
  • Page 80 Detailed description of the inspection and maintenance work Wipe off using a soft cloth (and some water with a normal household detergent). Leaking connections can be identified by moisture or crystals at the threaded connections of the hoses, at the sealing lips of the piston inside the dosing cylinder or at the valve. If any liquid becomes visible below the first sealing lip, it has to be checked at short timely intervals whether any liquid will build up under the second sealing lip, too.
