9.12 Internal Sample Dilution
Complex sample matrices and/or very high salt concentrations can have a strong impact on the sample
properties and the system, and/or seriously load individual components - something which can entail
higher maintenance effort. The “Internal sample dilution” option can be of assistance in these cases.
Here the sample is diluted with deionised water at an adjustable ratio. If ordered, the internal sample
dilution will be factory-preconfigured in the analyser.
9.12.1 Software Settings for the Internal Sample Dilution
The setting for the internal sample dilution can be configured in the “Measurement Parameters” display
(Chapter 7.7.1 on page 101) with User Level 3.
Notice
• With „Internal Sample Dilution“ the position for vessel V6 is used for the sample
dilution vessel. The pump GP7 transports the deionised water in this vessel.
Another position (Vx) is occupied with the rinsing vessel. Thus, when using this
option a maximum of 4 sample streams will be measured/are realized in the
analyser.
Notice
For appearance of this option in the software, it must be activated by LAR or
an authorized partner.
Users wanting to use the functions on User level 3 must have undergone training be-
forehand at LAR. If you are interested in technical training, please contact the Tech-
nical Support of LAR (Chapter 15 on page 283).
