Workflow Guidance (10 cm3)
Adding inserts and
cups to a nominal 10 cm3 chamber.
Upon initial
installation
- Make sure correct gas is selected.
- Perform Chamber Verification with two reference spheres
(about 6.37 cm3) and NO CUP.
- If Failed,
proceed to Calibration and then repeat step 2.
- If Passed,
proceed to next step.

- Navigate to Settings
> Inserts > Volume Standard. Manually enter
the volume reference values from the insert kit by clicking the plus
symbol.
- 3.5 cm3
reference (2.42 cm3), Tungsten Carbide (WC)
- 1.0 cm3
reference (0.72 cm3), Tungsten Carbide (WC)

For 3.5 cm3
insert, cup and cap
- Place 3.5 cm3 insert with no cup and no
cap in chamber.
- Navigate to Settings
> Inserts > Measure Volume. Select Insert
and measure.

- Place 3.5 cm3 cup with 3.5 cm3
reference sphere in 3.5 cm3 insert in chamber.
- Navigate to Settings
> Inserts > Measure Volume. Select Cup, then
choose Reference (2.42 cm3) and Insert (3.5 cm3),
then measure.

- Repeat steps 3 and 4, but include Filter Cap.
By the end, you
should have an insert volume and two cup volumes (one with cap and one without
cap).
For 1.0 cm3
insert, cup and cap
- Place 1.0 cm3 insert with no cup and no
cap in chamber.
- Navigate to Settings
> Inserts > Measure Volume. Select Insert
and measure.

- Place 1.0 cm3 cup with 1.0 cm3
reference sphere in 1.0 cm3 insert in chamber.
- Navigate to Settings
> Inserts > Measure Volume. Select Cup, then
choose Reference (0.72 cm3) and Insert (1.0 cm3),
then measure.

- Repeat steps 3 and 4, but include Filter Cap.
By the end, you
should have an insert volume and two cup volumes (one with cap and one without
cap).
For 0.1 cm3
cup
- Place 0.1 cm3 cup in 1.0 cm3
insert in chamber.
- Navigate to Settings
> Inserts > Measure Volume. Select Cup, then
choose Reference (-----------) and Insert (1.0 cm3), then
measure.

- Repeat steps 1 and 2, but include Filter Cap.
By the end, you
should have two cup volumes (one with cap and one without cap).
For 10 cm3
cup with filter cap
- Place 10 cm3 reference (6.37 cm3
Tungsten Carbide [WC] spheres) in 10 cm3 cup and cap in chamber.
- Navigate to Settings
> Inserts > Measure Volume. Select Cup, then
choose Reference (6.37 cm3) and Insert (-----------), then
measure.

- After measurement, label descriptively to distinguish
between standard cup and cup with filter.
Note: The
cup with filter is slightly shorter than the standard cup. If the filter is placed on the standard cup, the AccuPyc
chamber may not close and seal properly.
By the end, you
should have one cup volume (cup with cap).
Set up methods
- Create your methods and select the appropriate insert
and cup.
- When using a 10 cm3, 3.5 cm3,
or 1.0 cm3 sample cup, you can analyze the reference spheres as
samples and compare the measured volume to the certified values.

Acceptance criteria
Micromeritics tolerance is:
0.02% x (nominal
chamber volume + volume of reference)
For example, a nominal 10 cm3 chamber
with a 2.4250 cm3 sphere:
0.0002 x (10 +
2.4250) = 0.0025 cm3
Acceptable volumes would be 2.4250
± 0.0025 cm3.
End user may establish internal
acceptance criteria based on internal needs.
