<b>A comparison of Radiative Energy Attenuation and Titrimetric methods for the analysis of ethanol in blood</b> - DOI: 10.4025/actascihealthsci.v25i2.2165
Abstract
The alcohol determination in the blood was evaluated through the comparison of two analytical techniques, the method of radiative energy attenuation (REA) and the chemical titration method (TIT). The sensibility of REA was 0.4g/L and of TIT was 0.1g/L. The curve standard of etanol was linear up to 2.5g/L and 4.0g/L for methods REA and TIT, respectively. The coefficient of variation was 1.5% to 3.9% and 0.6% to 3.2% in the same day, and day-to-day coefficient of variation was 2.5% to 12.8% and 0% to 3.3% for methods REA and TIT, respectively. The tests of recovery presented the following results, 105% for REA and 88% for TIT. In 70 studied samples, the coefficient of correlation (r) was 0,9681 and the result of the test-t of Student was -1,294.Downloads
