Reportable data or final results are generated from raw data by mathematical or statistical calculations. Final results may be produced by direct readings from the instrument or calculations based on readings or instrument output. Before starting calculations make sure that all readings or outputs are correct and the selected formulas used in calculations are appropriate. Formulas and calculations should be recorded in the laboratory notebook or on the work sheet. In all records calculations are entered in ink and mistakes are never erased just cross through the error with a single line and date and sign. Generation of raw data and all related calculations and complete record keeping are the responsibility of the analyst. RESPONSIBILITIES OF THE ANALYST The following list contains the duties of the analyst from the selection of proper samples for a particular analysis through analytical performance including QC checks documentation calculations recognition and correction of problems and giving the accurate defendable result. Analytical work should be planned and organized so that laboratory time is used efficiently. The analyst should be familiar with the test method described in the laboratory SOP standard operating procedure . If samples require pretreatment drying digestion extraction etc. start as soon as possible because pretreatments are usually time-consuming procedures. If sample preparation is the duty of another laboratory section the analyst must be certain that sample preparation was correct collect all information required to calculate the final results volume or weight of the sample used for treatment final volume after treatment moisture of soil dilution or concentration etc. . Carefully select the accompanying pretreated QC check samples duplicates spiked samples laboratory control samples preparation blank equipment blanks .
