Provided is a system for adsorbing a gaseous component comprising nitrogen from a pressurized flow of air containing the gaseous component. The system comprises a first adsorption bed, and a second adsorption bed. Each of the adsorption beds are suitable for selectively adsorbing the gaseous component from the flow of air to produce a product gas having a higher oxygen concentration than that of the air. The system includes an adjustable feed gas supply which alternately supplies the first adsorption bed and the second adsorption bed with the air. The first adsorption bed is supplied with air during a first half cycle of operation of the system, and the second adsorption bed is then supplied with air during a second half cycle of operation of the system. The feed gas supply enables adjustment of at least one parameter relating to the amount or respective amounts of air being supplied to the first adsorption bed in the first half cycle and/or to the second adsorption bed in the second half cycle. A connection and valve assembly is provided between the first and second adsorption beds. The connection and valve assembly diverts a portion of the product gas, produced from the respective absorption bed being supplied with the flow of air during the respective half cycle, to the other adsorption bed. This causes previously adsorbed gaseous component to be released from latter. The released gaseous component then escapes from the system, e.g. to the atmosphere, via a vent. A sensor system determines a measure of the flow rate of waste gas, including the released gaseous component, escaping from the system via the vent. The at least one parameter can be adjusted based on the measure in order to tune the performance of the system. Further provided is a method for operating the system.

An optical particle sensor comprises at least first and second light sources of different wavelength for sequential operation. An optical detector is used to detect light from the light sources emitted or scattered by particles to be sensed. A current injection compensation signal is also provided which is dependent on which light source of the optical arrangement is in use.
