Note: To make sure that always the latest calibration file is ta-

ken for the calculation, the path of the calibration file defined

for the parameter Calibration curve on the Determination tab (of

the window EDIT WORKING METHOD PARAMETERS with cali-

bration

"DT Suppressors with calibration curve", must match

with the path defined for the parameter Data folder (for the cur-

rently logged-in user) on the tab User Directories of the window

USER RIGHTS.

Sample table

In the Sample table, list (according to the arrangement on the sam-

ple rack) for every Suppressor standard solution a method with

Calibration technique "DT Record calibration curve" and for every

sample a method with Calibration technique "DT Suppressors with

calibration curve":

Start determination.

Suppressor Analysis with 838 Advanced Sample Processor and RC

Following installations and settings are recommended for the au-

tomated Suppressor determination with the 838 Advanced

Sample Processor and the "response curve technique":

Note: The "response curve technique" is used for Suppressor de-

termination in electroplating baths, if the “dilution titration techni-

que" is inapplicable.

Instruments

Install the 838 Advanced Sample Processor, two 800 Dosi-

nos and a 732 Relay Box with two 823 Membrane Pump

Units (see Hardware Manual 797 and 838 Instructions for Use).
