| Popis: | The paper presents preliminary results for online measurement method of isopropanol concentration in the ultrasonic nebulization process using BW-Tek compact UV/Vis spectrophotometer. The experimental setup with nebulization vessel was constructed with a probe for on-line measurements. The tests were performed using a standard mixture of isopropanol and water with the volume isopropanol concentration in the range 19% to 83%. The results of on-line spectrophotometric method were verified using stationary spectrophotometer and a gas chromatography method. Linear calibration for the obtained data was performed and measurement uncertainties for the tested method were evaluated as confidence intervals. |
