20.6. Determining Density Using Pycnometer
Prior the procedure start, it is necessary to set process-related parameters:
−
Pycnometer weight (if pycnometer weight is known, the measurement is carried out
once when the pycnometer is filled with substance).
−
Pycnometer volume.
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
Procedure 1 – when the pycnometer weight has been entered
1. In order to record density value for a particular product in products database, go to
<Settings> menu, set <Assign density to product> parameter and press <Product>
quick access button to make the product active.
2. Press < Pycnometer> button.
3. Respective menu is displayed, using it set the following parameters: pycnometer
weight, pycnometer volume.
4. Press < START> button.
5. Process of density determination begins.
6. Fill in the pycnometer with tested substance, follow the pycnometer guidelines.
7. Load the pan with a pycnometer, wait for a stable measurement result and press
< > button.
8. Density result is displayed.
9. Press < > button to complete the procedure.
CAUTION:
Press < > button to start new density determination process with the same settings.
Procedure 2 – when pycnometer weight has not been entered
1. In order to record density value for a particular product in products database, go to
<Settings> menu, set <Assign density to product> parameter and press <Product>
quick access button to make the product active.
2. Press < Pycnometer> button.
3. Respective menu is displayed, using it set the following parameters: Pycnometer
volume.
4. Press < START> button.
5. Process of density determination begins.
