11. Analysis
In this part of the main menu distillation and titration are performed.
11.1. Safety instructions
Attention when handling acids and alkalis! Please observe your national safety regulations!
Use gloves when removing the glass digestion tubes as these will be very hot and there is danger of
burning yourself! Also make sure you wear eye protectors!
Be careful whenever handling glass and follow the national safety regulations concerning the hand-
ling of glass parts!
11.2. Before starting with the analysis
Test Run
In order to obtain results which can be reproduced easily make sure you run a distillation without
sample before you distil a sample. To start choose key "Clean" from the initial display of the analysis
program (see chap. 11.3.1. step 10 or chap. 11.3.2. step 12).
Check the chemical reservoirs
Check the connections of the reservoirs regularly.
Turn on tap
If the tap is not turned on the system is not working.
11.3. Single determination or serial determination
Serial determination means that the weights or volumes have already been stored in the main menu
"Sample Input" and can be worked on one after the other.
Single determination means that the weight or volume is entered before each analysis. An average
value of results or blind values cannot be calculated in that case.
