Aerosol Measurement

Dekati® Low Pressure Impactor DLPI

The DLPI is a 13-stage cascade impactor used for the measurement of gravimetric particle size distribution. It has the ability to classify particle size from 10 µm down to 30 nm, with an optional filter stage accessory enabling the collection of particles below 30 nm. Currently, the DLPI is only available with a sample flow rate of 30 lpm.


Dekati® PM10 Impactor

A three stage cascade impactor for determining particle gravimetric mass size distribution. 

The PM10 impactor provides information on the PM10, PM2.5 and PM1 mass size fractions. The PM10 impactor is available in 10 lpm or 30 lpm versions and complete setups can be provided for different applications including airl quality monitoring and combustion flue gas measurements.



The DLPI+ (Dekati®Low Pressure Impactor) classifies particles into 14 size fractions, from 10 microns down to 16nm.  A chemical analysis of the size classified particles can also be performed. The DLPI+ impactor can be used in various particle measurement applications and can be heated up to 180°C with the DLPI+ Temperature Kit.  The kit includes a heating jacket for the impactor and integrated temperature control unit.



The ELPI®+(Electrical Low Pressure Impactor) is an improved version of the widely used ELPI® system. This instrument enables the measurement of real-time particle size distribution and concentration in the size range of 6 nm – 10 μm, with up to a 10 Hz sampling rate.  The ELPI®+ can also be used for real-time particle charge distribution and for gravimetric impactor measurements.  Chemical analysis of the size-classified particles may also be conducted post-measurement.  

Benefits of the ELPI®+ system include:

  • Real-time stand-alone operation
  • Wide sample concentration range 
  • Wide particle size range
  • The ability for post-measurement chemical analysis of size classified particles  
  • Real-time particle charge distribution and gravimetric measurements

High Resolution ELPI®+

The High Resolution ELPI®+ operates in the same manner as the ELPI®+ but features a data inversion algorithm that provides the user with real-time particle size distribution in up to 500 size classes in the size range of 6 nm - 10 µm.  The data inversion software may be purchased separately and used with the traditional ELPI®+. 


Dekati® DePS™-GO

The Dekati® DePS™-GO (Dekati® electrical Particle Sensor) is a miniature sensor for determining real-time particle lung-deposited surface area (LDSA).  The measurement signal can also be correlated to particle number or mass concentration.  The DePS-GO is a versatile device that can be controlled and monitored either by touch-screen display or external I/O data communication.  Power is provided by a built-in battery or the USB-power socket, making it perfectly suitable as a portable or stand-alone measurement tool. 


Aero Select

The ANCON Aero Select is a portable, wide-range aerosol sampler that detects fine aerosol particles from 2nm to 20µm in size. Particles are collected simultaneously and separated into 12 sample stages.  The Aero Select is portable and is built for field use, with the accuracy of an in-house laboratory instrument.  Sampling can be continuous or segmented for optimal data collection. 


Aero Particle Sizer

The ANCON Aero Particle Sizer is a portable nanoparticle spectrometer that operates in one of two modes: 

  • Spectrometer Mode - combining data from a scanning mobility particle sizer (SMPS) and optical particle counter (OPC), which covers the size range of 10nm to 17µm with over 100 channels
  • Condensation Particle Counter (CPC) Mode - for particle number concentration measurements

The built-in computer allows unattended operation, data storage and processing.
