An analytical instrument device is provided which can be used for analyzing industrial gas and air emissions. The device is operative to accumulate aerosols from gases and includes an atomizer connected to a gas pumping system, a needle, and a high-tension power supply. The atomizer includes a hollow cylinder provided with a dosing hole which is arranged in the central part of a lateral surface thereof. The gas pumping system includes a dosing hole of the atomizer with a needle arranged therein. The needle is provided with a movable platform for moving it in relation to the atomizer. An orthogonal system used for introducing the gas flow through the dosing hole of the atomizer makes it possible to essentially increase (by 6 times) a pumping speed and correspondingly to reduce the time of a sample accumulation.
