PROGRAMMABLE ATMOSPHERIC SAMPLING SYSTEMS AND METHODS

摘要

A sampling system controller includes a control unit for interfacing with a collection chamber module having a plurality of sampling chambers. The control unit controls the times at which the sampling chambers acquire samples of a fluid flow and control flow rates into the sampling chambers. The timing of the sampling chambers and the flow rates may be programmed by a user. The control unit measures the flow rate of the fluid flow to be sampled and controls the flow rate through each sampling chamber. The flow rates through the fluid flow and through the sampling chambers are recorded on a data module. The control unit may be equipped with a portable weather station and with a global positioning system. The weather and location information may be recorded on the data module. The flow rates through the sampling chambers are controlled by a flow assembly that is easily removed and replaced.
