A semi-volatile particulate matter detection device is disclosed for detecting semi-volatile particulate matter in a gas flow. The device has a first filter stage for receiving the gas flow, the first filter stage being configured to capture particulate matter and to be heated to a temperature of at least 150° C. to volatilise semi-volatile particulate matter to produce semi-volatile vapour for passing through the first filter stage with the gas flow. The device also has a conveyance section downstream of the first filter stage to convey the gas flow and the semi-volatile vapour. A second filter stage is configured to receive the flow from the conveyance section. The temperature of the conveyance section and/or of the second filter stage is controllable so as to cause condensation of at least some of the semi-volatile vapour and collect it on the second filter stage. A detector is provided for detecting at least one characteristic of the condensed semi-volatile vapour on the second filter stage.

A particle sensor for measuring size and concentration properties of particles in a gas includes a bipolar diffusion charger configured to charge particles within a received gas sample by the collision of the received particles with and transfer of charge from both positive and negative ions concurrently. At least one electrometer detects the charge of received particles thereby charged. The net, positive, negative or total charge on the bipolarly charged particles has a low sensitivity to variations in the absolute rate of charge generation in the bipolar diffusion charger. A sensor for a ratio of ion charge mobilities in a bipolar diffusion charger employs an ion trap between the bipolar diffusion charger and at least one electrometer.

Particle sensor and sensing method

An apparatus for the production of nanoparticles is provided. The apparatus includes a main tube that is closed at a bottom, an inlet channel arranged within the main tube and includes a first opening to the outside of the apparatus and a second opening to the main tube, and a main opening in the main tube. The main tube includes a sample position at the bottom, the cross section of the main tube at the sample position is smaller than at other positions of the main tube, and the second opening of the inlet channel is arranged closer to the sample position than the main opening. Furthermore, an arrangement for the production of nanoparticles and a method for producing nanoparticles are provided.

A thermodenuder having a main tube with an outer wall, and a heater () arranged within the main tube. The heater is arranged in the center of a cross section through the main tube and is spaced apart from the outer wall of the main tube. The main tube has a main axis of extension, and the heater extends parallel to the main axis. The main tube has two openings that are arranged at opposing side faces of the main tube. A channel for an aerosol is arranged within the main tube between the heater and the outer wall and between the two openings. Furthermore, a method for removing semi-volatile material and semi-volatile particles from an aerosol is provided.
