Abstract

The invention discloses a sampler for multi-channel gases and particulate matters and a using method of the sampler. The sampler comprises a sample gas inlet, a first multi-way pipe, a sampling head, a flow sensor, a display screen, a keyboard, a USB interface, a singlechip, an ambient temperature sensor, a pressure sensor and an atmosphere pressure sensor, wherein the sample gas inlet is connected in parallel with the sampling head through the first multi-way pipe; a gas outlet of the sampling head is connected with the flow sensor, the pressure sensor and an air exhaust device; the flow sensor, the air exhaust device, the display screen, the keyboard, the USB interface, the ambient temperature sensor, the atmosphere pressure sensor and the pressure sensor are electrically connected with the singlechip. The invention provides the sampler, so that operations of multiple samplers can be finished, several samples are simultaneously collected according to the types of the selected sampling head. Therefore, according to the sampler for multi-channel gases and particulate matters and the using method of the sampler, the labor cost and transportation cost are reduced, and the purchase cost and operating energy are saved.

Description

technical field [0001] The invention relates to the technical fields of environmental protection monitoring and aerosol monitoring, in particular to a multi-channel gas and particle sampler and a use method thereof. Background technique [0002] Existing gas or particulate matter samplers can only collect one sample at a time, while environmental monitoring needs to collect many types of samples, including TSP, PM10, PM5, PM2.5, PM1 and other particulate matter; metal dust, microorganisms, SVOCs; and Radioactive aerosols, iodine-131 and other radioactive aerosol samples; also include fluoride, volatile organic compounds and other harmful gases and aerosol samples. The device for collecting the above samples is hereinafter referred to as the sampling head. Such as PM2.5 cutter and filter membrane, SVOCs sample collection device, etc. are referred to as sampling head for short. When collecting two or more gas or particle samples at the same time, two or more samplers are req...
