Aerosol Measurement

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.

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.

A cascade impactor with cutpoints of 2.5, 1.0, 0.5 and 0.2 microns and a back-up filter. 

The particles are collected on Ø47 mm filters with sample flow rate of 70 lpm. DGI is typical used in combustion measurements including automotive emission testing, but it is can be applied to any measurements where particles in its operational range exist.

The Dekati® High Resolution ELPI®+ (Electrical Low Pressure Impactor, HR-ELPI®+) is an improved version of the widely used ELPI®+ instrument. Since 2024, the HR-ELPI®+ is offered as the standard ELPI®+ version.

The High Resolution ELPI®+ utilizes a data inversion algorithm that gives real-time particle size distribution in up to 500 size classes 6 nm – 10 μm. Other High Resolution ELPI®+ features include wide particle sample concentration range, robust structure and possibility to characterize chemical composition of size classified particles after the real-time measurement. The latest addition to the HR-ELPI®+ features is a new Data Analysis Tool software that makes data analysis and visualization fast and easy for the instrument operator. This new tool comes with particle number, LDSA and mass concentration (6nm-2.5 μm) calculations for the HR-ELPI®+.

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

Pegasor Airin is a compact standalone monitor for monitoring ultrafine particles in indoor environments. The Airin unit uses the Pegasor PPS-G2 sensor for real-time measurement of particle number (PN), lung deposited surface area (LDSA), particle mass (PM) concentrations and also particle size. The Pegasor Airin is an ideal tool researchers, occupational hygienists, or anyone concerned about healthy indoor air to monitor ultrafine particle concentrations as recommended by the WHO (global air quality guidelines 2021).

Pegasor Particle Counter PPC is a complete, stand-alone measurement system for particle emission monitoring applications. Powered by the Pegasor PPS-G2 particle sensor, the PPC is an easy-to-install system for fast and reliable testing of particle emissions from engine/vehicle tailpipe or other emission source. The system fulfills all requirements and recommendations set in the new European regulations for measuring particle number concentration from vehicle exhaust in PTI applications but it is equally suited for any other exhaust or emission monitoring application.

The PAM 510 Process Aerosol Monitor is an accessory to Topas’ Condensation Aerosol Generator SLG 270, and is used for the continuous monitoring of particle size and concentration of monodisperse aerosols.

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.

The Aerosol Particle Mass Analyzer (APM 3602) classifies particles by mass, based on the balance between centrifugal force and electrostatic force.  This desktop unit classifies aerosol particles of 0.001 ~ 565 femtograms (Equivalent to approx. 12 ~ 1,008 nm for particle density of 1 g/cm3).   

The APM can be used in the following applications:

• Mass distribution measurements
• Particle density research
• Monodisperse aerosol generation

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 Airam is a standalone ultrafine particle monitor ambient, outdoor air quality measurements. The Airam system is powered by the Pegasor PPS-G2 sensor that provides real-time and accurate information on particle number (PN), lung deposited surface area (LDSA), particle mass (PM) and particle size. The Airam goes beyond traditional PM10 and PM2.5 measurements, aligning with the new European Union Ambient Air Quality Directive, setting stricter limits on key air pollutants, including ultrafine particles (UFPs). The new directive aligns more closely with the World Health Organization’s (WHO) air quality guidelines, aiming to reduce pollutants which are known to cause respiratory and cardiovascular issues.

The GMS 141 Gravimetric Measurement System is a heated filter collection system designed to measure oil content in crankcase blow-by aerosols.  A by-pass line allows separators to be brought up to operating conditions prior to filter collection, and a pressure drop measurement across the filter allows consistent mass loading for uniform results.
