Sample uptake

9.11.2

Method: Select sample feeding

9.11.3

Method: Select intermediate cleaning

1. Access the method with intermediate cleaning selected under Tab Cleaning.
2. Start the cleaning via SERVICE > Tab Functions > Function Cleaning.
The cleaning selected in the method will be performed.
To work with the autosampler, the sample uptake, type of sample uptake, intermediate
cleaning and final cleaning must be defined. All autosampler settings are specific to the
method.
The speed and time of sample uptake are defined with the pumping parameters.
The factory setting values for the pump are as follows:
• Revolution speed: 50 rpm
• Pumping time: 10 s
• Counter-clockwise rotation
The pumping time and revolution speed should only be modified where required (e.g. for
very viscous samples).
1. Access the required method via METHOD.
2. Select under METHOD > Tab Sampl. > EDIT.
3. Select Sample feeding autosampler.
The factory setting values are displayed.
With factory setting values, complete filling of the frequency oscillator is usually
guaranteed. The pumping time and revolution speed should only be modified where
required (e.g. for very viscous samples).
If the frequency oscillator requires cleaning between individual measurements,
intermediate cleaning must be selected in the current method.
1. Access the required method via METHOD.
2. Select under METHOD > Tab Sampl. > EDIT.
3. Select Sampler mode > Intermediate cleaning .
4. Select the required intermediate cleaning from Intermediate cleaning procedure .
