PROBLEM TO BE SOLVED: To accurately determine a liquid volume of a droplet, and to collect only the droplets of stable liquid volume, in a liquid droplet weighing collection device for bringing a sample liquid into the fine droplets to be dropped from a tip of a nozzle, and for collecting the droplets. SOLUTION: In this device provided with a metering feed pump 12 for the sample liquid, the liquid dropping nozzle 22 connected to the metering feed pump, and a collecting pipe 24 for collecting the droplets dropped from the dropping nozzle, a droplet sensor 60 is provided to measure the number of the droplets and a dropping time interval. The droplets when the dropping time interval is stable are collected out of the droplets dropped from the dropping nozzle by the collecting pipe, an average value of the liquid volume of the droplets is computed based on the amount of the sample liquid fed from the metering feed pump to the dropping nozzle, and based on the number of the droplets dropped from the dropping nozzle, and the average value of the liquid volumes of the droplets is determined as the liquid amount of the collected droplets collected by the collecting pipe.
