Sequential Volatile Organic Compound Sampler

Sample collection system in absorption tubes for post-laboratory analysis The instrument is intended for the collection of volatile organic compounds in the atmosphere. The collection is carried out by means of tubes with chemical absorbers, of daily sampling, which allow the collection. The equipment has a sequential module in order to be able to carry out several days of continuous field work. Operation, measurement and regulation of the flow controlled by microprocessor and mass flow measurement. Automatic regulation and constant maintenance of the programmed flow rate, with automatic compensation of load loss due to filter clogging or network fluctuations. Communication interface with the user through a 240 x 128 p LCD screen and keyboard.

Technical features
