Aerosol Measurement

DLPI+

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 also be heated up to 180 °C for high temperature measurements.

Dekati

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

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®e-Filter™

The Dekati®e-Filter™ adds real-time PM detection into a standard, US EPA 40 CFR Part 1065/1060 filter holder.  The e-Filter™ fits into all existing PM filter sampling systems, including CVS and partial flow tunnels.  This compact unit is battery operated and includes a diffusion charger with electrical detection for real-time measurement.  All data is saved to a micro-SD memory card.

Dekati

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.

Dekati

High-Temperature ELPI+

The Dekati® High Temperature ELPI®+ is a version of the ELPI®+ that allows for the direct measurement of heated aerosol samples up to 180° C.  The high temperature measurement avoids changes to the sample that can occur during cooling and dilution.

Dekati

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.

Dekati

M-Sensor

Pegasor’s M-Sensor can directly measure raw, hot combustion emissions without the need for dilution or conditioning.  The resulting measurement is expressed as mass concentration and/or number concentration.  The M-Sensor can be used in a variety of applications, including:

  • Engine and after-treatment development
  • On board diagnostics
  • Stack emissions monitoring
  • Outdoor and indoor air quality monitoring 
Pegasor

Mi3

The Mi3 is a cost-effective, turnkey system for automotive PM measurements in engine dynamometers, chassis dynamometers, and on-board applications.  Utilizing Pegasor M-Sensor technology, the Mi3 can directly measure raw, hot engine emissions without the need for dilution or conditioning, reducing cost, complexity and uncertainty.

Diluters & Conditioners

Dekati Thermodenuder

The instrument makes detailed studies of soot particles possible by removing volatiles from automotive exhaust. Removal of the volatiles eliminates unwanted sample transformations. The high flow rate of the instrument makes it an ideal tool for use with ELPI™ (Electrical Low Pressure Impactor) and DMM (Dekati Mass Monitor). 

Dekati

Dekati Cyclone

An EPA-standard cyclone for removal of large particles from a sample stream.

The cyclone can be used in high temperatures due to the all-stainless steel construction. The Dekati cyclone is manufactured according to EPA standard 201A. 

Dekati

Dekati Axial Diluter DAD-100

A simple and cost-effective dilution tool for any dilution task.

Especially designed for use with Dekati instruments, the DAD-100 is very simple to install into any sampling or measurement system. All-stainless steel design makes it also possible to heat the diluter up to 500°C. 

Dekati

Dekati® High Pressure Diluter DEED-300

The Dekati® DEED-300 is an aerosol diluter capable of sampling from pressures of up to 1 bar in standard configuration, and up to 10 bars in custom configurations.  Available as a single-stage 4:1 diluter, or as a two-stage 40:1 diluter, it features low losses and good time response.  The DEED-300 can also be heated and is often used in front of additional dilution and sample conditioning devices such as the DEED-100 when measuring high temperature combustion processes.

Dekati

DEED

The Dekati® Engine Exhaust Diluter (DEED) is a simple, easy-to-use engine exhaust conditioning and dilution system.  It meets all the requirements of EURO 5b/6 legislations for solid particle number count applications, but offers the flexibility to be used for traditional, particle mass measurements as well.  

Dekati

Dekati Diluter DI-1000

A low-cost, simple and easy-to-operate device for diluting aerosol and gaseous samples from any source.

The simplicity and robustness of the all stainless-steel design have made it a widely renowned choice for dilution of combustion aerosols.

Dekati

Fine Particle Sampler FPS-4000

A sophisticated two stage dilution system for sampling combustion aerosols and other hot gases.

The FPS features hot or cold primary dilution, adjustable dilution ratio up to 200:1 diluted sample flow up to 220 lpm and real time temperature and pressure correction.
