An automated vibrating-tube densimeter for measurements of small density differences in dilute aqueous solutions.
Original language description
Automated sampling device for a vibrating tube densimeter is described. Two sampling sections are connected in series in the filling line of the densimeter. One of them is employed for manual filling of the measured sample into a sampling loop using a syringe. The other section allows fully automated measurement of up to 12 samples in one run. A set of 12 storage bottles is connected to the 1-to-12 switch-over valve. The liquid sample is pumped by a peristaltic pump to the sampling loop through a systemof two sampling valves (3x2) that inserts the loop content into the filling line of the densimeter. The pump and valves are controlled by a computer program that also stores the measured data (period of vibrations of the tube, temperature, and pressure vs. time) along with necessary information on the measured samples in a data file. The automated measurement of a set of 12 sample solutions (each being measured three times) can be completed within about 18 hours. The recorded data are ev
