Re-Weighing the Samples
1. Measure and record the dry mass using the balance (See "Measuring Mass" p. 19)
Note: the dry mass measurement is required for MAD property
calculations.
2. After the dry mass measurement, the dry volume (method “C”) can be taken. Use the
MAD software to operate the pycnometer (See "Measuring Volume" p. 22).
Note: at least one of the three volume measurements (A, B, or
C) must be taken. The dry volume measurement is the preferred method of operation.
Storing the Samples
1. Place the sample in a plastic bag with the corresponding barcode label.
2. Matching the beaker number on the barcode label with the number on the beaker identifies
the bag.
Note: this step is very important as these residues are often used
by other scientists for analysis.
Exporting Sample Data to Janus
Once samples are analyzed and the data recorded, they are ready to be uploaded to the central
Janus database. See "Appendix B. File Formats" p. 29 for details on uploading.
