21.3. Solids Density Determination
Prior the procedure start, it is necessary to set process-related parameters:
−
Liquid type
o
Distilled water
o
Ethanol
o
Other liquid with determined density
−
Liquid temperature
(required if either distilled water or ethanol is used as liquid for measurement
performance)
−
Liquid density
The parameter is set automatically, after the temperature has been entered, if
either distilled water or ethanol is used as liquid. In case of using liquid other than distilled
water or ethanol, it is necessary to enter its density manually.
The density of solids is calculated using the following formula:
o
B A
A
ρ ρ
−
=
ρ
- density of a sample
A - sample mass measured in the air
B - sample mass measured in liquid
ρ
o
- liquid density
Determination of density for a particular solid consists in weighing the solid in the air first,
and in the liquid next. Upon completed procedure the result is displayed automatically.
Procedure:
1. Install density determination kit.
2. Enter <SOLIDS DENSITY> function.
3. Prepare sample that is to be measured.
4. Start the process by pressing button (Start).
5. Select liquid type intended for the test performance.
6. Enter the liquid temperature (the program displays the most recently operated
temperature value).
7. If liquid assigned to MISC parameter is used, enter its density for the entered
measurement temperature.
8. The following message is displayed:
9. Put your sample on a top weighing pan (sample weight measurement carried out
in the air), wait for a stable indication and press either or key to
confirm
.
10. The following message is displayed:
11. Now put your sample on a bottom weighing pan (sample weight measurement
carried out in the liquid), wait for a stable indication and press either or
key to confirm
.
