Maurício, C. Dias, F. Santana] Abstact: The present study was designed to evaluate indirect, non-invasive, on-line measurement of biofilm thickness using an electrical capacitance technique. Several assays were carried out and the results showed that, at a frequency of 1 kHz, electrical capacitance could be used to measure biofilm thickness indirectly (with a correlation coefficient of 0.9495). The reproducibility revealed by the assays was also highly satisfactory. However, in contrast to what was expected, there was an inverse relationship between electrical capacitance and biofilm thickness, i.e. electrical capacitance diminished with the increase in the biofilm thickness. The tests were also carried out at different frequencies (1 kHz, 10 kHz and 100 kHz) Springer Science+Business Media, Inc., 2006 electrical capacitance nationallicence biofilm thickness nationallicence non-destructive technique nationallicence on-line measurement nationallicence Maurício R.
