Verify Operation

Verify operation of the pycnometer by performing an analysis on the calibration standard to ensure that the pycnometer is operating properly.

  1. Go to Unit [n] > Sample Analysis.
  2. Click New to create a new sample file.
  3. Click Replace all and select the refanly.smp file. The values in the current file will be replaced with those contained in refanly.smp. Click OK.

  1. Click Report After Analysis. Select the Report after analysis option, then click OK.

  1. Click Start to begin the analysis.
  2. Compare the value displayed for the average volume to the value recorded on the calibration standards case. These two values should agree plus or minus the tolerance obtained using the following calculation:
  3. Tolerance = (chamber volume * 0.0003) + (Value recorded on Standards case * 0.0003)

    Example: calculate the tolerance for a 10 cm3 pycnometer with a value of 6.372242 cm3 recorded on the case as :
    Tolerance = (10 * 0.0003) + (6.372242 * 0.0003) = 0.003 + 0.0019116726 = 0.005 cm3

If the values do not agree, a leak may be indicated. Check the system for leaks. Then repeat steps 1 through 6. If the values continue to disagree, contact your Micromeritics Service Representative. See Diagnostics using the Software.

  1. Remove the standards and place them back into the case.
