ABSTRACT
Reports of analyses are the written records of analytical work. The content of the report should include all of the necessary information and should be clear and understandable for the end-user. All documentation used to approve and defend reported data must be collected and should be available and referenced so it can be found at any time it may be needed. Numerical data are often obtained with more digits than are justified by their accuracy and precision. Units used to express analytical results depend on the analytical method used, the concentration of the analytes, and the matrices of the sample analyzed. Reporting the calculated confidence interval (CI) of the measurement helps to estimate the reliability of the result. A simple table form is accepted for regular, routine reporting. It should be clear, easy to follow, and should contain all of the necessary information to evaluate the analytical report.
