To one per page. Clear tape or glue may be used. Do not use staples. Only one fold in attachments is allowed. Do not cover any notebook entries with attachments. V. Results A. The results of the project, such as numerical values representing analysis results, should be reported in the notebook in table form if appropriate. Otherwise, a statement of the outcome is written, or if a single numerical value is the outcome, then it is reported here. In order to identify what is to be reported as results, consider what it is the client wants and needs to know.

Thus, a mixing procedure and a procedure by which a sample is divided to create the required portions may follow particle size reduction. 3. In addition, to ensure that the solid particles are of uniform size, they may be passed through a sieve (see Chapters 3 and 15 for descriptions of sieves). 3 Solid–Liquid Extraction An analyte may be present in one material phase (either a solid or liquid sample) and, as part of the sample preparation scheme, be required to be separated from the sample matrix and placed in another phase (a liquid).

Any device routinely checked for calibration can be monitored in this way. For example, an analytical balance can be tested with a known weight, the value of the known weight being the desirable value and the expected range of precision dictating the warning and action limits (Experiment 1). A procedure or method may be checked by the use of a quality control solution (often called a control), a solution that is known to have a concentration value that should match what the procedure or method would measure.
