LIMS data entry guidelines are <br />also posted at al! station terminals as a ready reference source for analysts. <br />Analysts must proofread all analytical and quality control data which they <br />enter into LIMS before exiting the system. All data calcwlations, dilution <br />factors, etc. must be verified prior to LIMS data entry. If LIMS data entry <br />requirements are unclear, contact a laboratory section supervisor or the <br />QA/QC coordinator before entering this data. <br />Significant Fi ures <br />Do not report analytical or quality assurance data to more than three <br />significant figures in LIMS. Exceptions to this policy are explained during <br />analytical method training. <br />Do not record analytical or quality assurance data using more decimal places <br />than are specified for the method detection limit. <br />Method Detection Limits <br />Samples which have been diluted due to matrix interference, analyte <br />concentration, or lack of sample must have their detection limit manually <br />changed (increased) in LIMS during data entry. <br />Verify the LIMS default detection limit when entering data. If this detection <br />limit is incorrect, contact a laboratory section supervisor or the QA/QC <br />coordinator. <br />Method References <br />Method references must be changed during data entry if the default LIMS <br />method reference varies from the analytical method which was used for <br />analysis. <br />Units <br />FE VISION NG.
