Validation spreadsheet: A new tool for estimating the analytical figures of merit for the validation of univariate methods

This work presents the VALIDATION SPREADSHEET, a public domain tool that can be used to evaluate the figures of merit for univariate analytical methods. A real example of BTEX determination in environmental samples is included to illustrate its use. The spreadsheet has been developed for Excel (R) and Open Office (R), and is available on the internet at http/lqta.iqm.unicamp.br.
