A method using Laser Induced Breakdown Spectroscopy (LIBS) for calcium (Ca) determination in breakfast cereals was evaluated. To perform the calibration curve, seven commercial cereals containing Ca in a range of 16.00?3734 mg kg1 were considered. The Ca amounts provided by the manufacturers were evaluated by using inductively coupled plasma optical emission spectrometry (ICP OES). The precision of the LIBS measurements was of 8% and the accuracy, observed by using a corn bran standard reference material was higher than 99%. The method was successfully applied to predict the Ca concentration in a set of commercial samples dispensing the sample pre-treatment, with the potential to be used in production. lines. |
