Aerosol Measurement


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.


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 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.


Dekati® Low Pressure Impactor DLPI

A 13-stage cascade impactor for measuring gravimetric particle size distribution. 

The DLPI size classifies particles from 10 microns down to 30 nm with an optional filter stage accessory enabling collection of particles below 30 nm. DLPI is available with sample flow rates of 10 and 30 lpm.

Note:  This product is only available for purchase through December, 2019.  It is no longer found on Dekati's website.  If you need additional information, please contact Particle Instruments.


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. 


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®+. 



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

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.


Piezobalace Dust Monitor Model 3521 / 3522

Direct particulate mass measurement based on a piezo-crystal inertial balance.


Handheld Condensation Particle Counter Model 3800

This handheld, direct-reading instrument screens for nanoparticles in the size range of 0.015 - 1 µm, and concentration of 0 - 100,000 particles/cm3.  When accompanied with an extension probe, it is extremely useful for sampling hard-to-reach areas.  The 3800 can be used in a variety of applications, including:

  • Indoor air quality investigations
  • Engine exhaust testing
  • Aerosol research 
  • Occupational health control


The Portable Aerosol Mobility Spectrometer (PAMS) is an electrical mobility spectrometer designed for portable, mobile or hand-held aerosol sampling applications.  This instrument provides the number-weighted diameter distribution of aerosols in the 10-863nm size range.  It can be used in two modes:  single diameter count or size distribution.

The PAMS may be used in the following applications:

  • The measurement of both indoor and ambient air quality
  • Combustion and engine exhaust emission measurements
  • Filtration studies
  • Inhalation toxicology studies
