Since 2002 Cambustion have offered a range of aerosol instruments designed for aerosol science & laboratory applications.
The 2016 launch of the Aerodynamic Aerosol Classifier (AAC) adds a unique and novel measurement technique to Cambustion's range of aerosol instruments.
The Centrifugal Particle Mass Analyser (CPMA) has been adopted worldwide since its launch in 2012, offering researchers the ability to characterise particle density and morphology.
The flexible sampling capabilities and and rapid response times of Cambustion's established DMS500 and SCS systems make these highly suited to aerosol laboratory work, an application which has grown significantly as the research community seeks to update older equipment (e.g. SMPS).

Electrical Mobility Size Distribution Measurements
The SMPS (Scanning Mobility Particle SizerTM) by TSI is an example of a scanning instrument offering electrical mobility measurements, using a Differential Mobility Analyzer (DMA) and Condensation Particle Counter (CPC). Such a system offers excellent sensitivity, but requires around 60-90 seconds to make a single measurement.
Cambustion's DMS series instruments offer real-time electrical mobility based particle size/number spectra. The Engine Exhaust Particle Sizer (EEPSTM) and Fast Mobility Particle Sizer (FMPSTM) instruments made by TSI operate on a similar principle.
The DMS500 offers excellent sensitivity at the small end of the size range. High charging efficiency and low diffusion losses through the use of sheath flows and high sample flowrates make the DMS500 particularly attractive when particles smaller than 50nm are to be measured.
Since the purpose of real-time instruments is to study rapidly changing particle spectra, Cambustion’s DMS series products are carefully designed to achieve the fastest possible fluidic response time and fast data rate (As low as 200ms T10-90% response time, and 10Hz sampling / 0.1 second resolution).
Together these make the Cambustion DMS500 the solution for studying transient aerosol phenomena. The fully integrated dilution system and classifier interface seamlessly, with full control, measurement and data correction of all flows.
With optional integrated dilution for sampling high concentration aerosols, heated sampling systems for sampling wet aerosols and high sensitivity for ambient measurements, the DMS500 is used in laboratories around the world for aerosol measurement, offering particle size distributions in the range 5 nanometres - 2.5 microns.
The DMS software offers unique real-time lognormal fitting, a feature which is of particular use when sampling artificial aerosols with narrow gsd.

Filtration Efficiency Studies
Many aerosol experiments involve comparing the input and output of a piece of equipment.
The unique Dual Sampling Accessory for the DMS series allows electrical switching of the sampling location between two points- for example upstream and downstream of a filter.
Aerosol Diffusion Dryer
Many laboratory aerosol experiments require the removal of moisture from aerosols, often with a requirement to avoid reduction of particle concentration during the process. (This can make dilution an unattractive solution.)
The Aerosol Diffusion Dryer uses silica gel to remove water from an aerosol, while maintaining high transmission efficiency of the remaining particles.
PSL Particle Size Check
Verifying the sizing accuracy of aerosol instruments is more difficult than for gas analyzers, since aerosols can not be stored. The commercial availability of Polystyrene Latex Spheres as NIST traceable size standards offers a comparatively convenient solution.
The PSL Size Check Kit offers a standalone means of nebulizing and drying PSL, allowing it to be presented directly to an aerosol sizing instrument.
Many aerosol experiments require a means of removing pre-charged particles from the aerosol flow, either to prevent interation with downstream measurements, or to quantify the proportion of un-charged particles to allow compensation in data processing.
The Aerosol Precipitator uses an electrical field to precipitate pre-charged particles out of the flow, while allowing uncharged particles to pass through. It is often used in general lab work, or with the CPMA.
Cambridge Particle Meeting
Cambustion also sponsor the annual Cambridge Particle Meeting which is attended by aerosol and particle researchers from around the world.
