METHODS
5.7 Bromine Index
The
HI 904
is capable of performing Bromine Index/Bromine Number determinations. Bro-
mine Index/Number is a measure of the unsaturation of hydrocarbons, expressed as the
amount of bromine required to react with 100 g of sample. Bromine Index is expressed as
mg Br/100g; Bromine Number is expressed as g Br/100g. The
HI 904
can be set up to
perform Bromine Index determinations by following the steps:
(1)Prepare the titrator according to Section 2 of the manual, except remove all desiccant
from the desiccant cartridges. Bromine Index reagents contains water and will rapidly
saturate desiccant.
(2)Fill a GL45 bottle with Bromine Index reagent. Consult a standard method for preparation
instructions.
(3)Connect the Bromine Index reagent bottle to the titrator and fill the vessel according
to Section 2 of the manual.
(4)Set a method to “Bromine Index” mode by either selecting a bromine index standard
method (e.g.:
HI 9901EN
), or by creating a custom method:
• Go to the
Select Method
screen. Create a new user method for Bromine Index
determinations. Select this new method.
• Go to
Method Options
section, then
Type:
.
• Select
Bromine Index
.
• Exit
Method Options
. Remember to save the changes to the method.
(5)Press
.
There are several changes to the user interface while running a Bromine Index method:
• “Drift Analysis” mode has been removed.
• “Relative Drift” and “Absolute Drift” termination criteria have been removed.
• All calculations are as
µ
g (or mg) Bromine.
• Result units have been changed to appropriate Bromine Index units.
