Ambient Aerosol Research & Monitoring
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 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.
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 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 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.
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
The Time of Flight Mass Spectrometer (infiTOF) is a high-performance, small footprint time-of-flight mass spectrometer. Portable, yet sensitive. It does not sacrifice resolution.
The infiTOF may be used in the following applications:
- In-field analysis
- Forensic analysis
- First response to environmental hazards
Nanosampler Model 3182
A low pressure impactor (LPI) is usually used for sampling PM0.1, however, an LPI requires a low pressure vacuum or it will cause a change in particle composition. The Nanosampler can be used to sample a greater amount of PM0.1 particles at ambient pressure without causing a distortion in particle composition.
Enabling the use of a higher sampling flow, 40L/min, shortens the sampling time needed for the weighing or analysis of particle matter.

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 Aerosol Particle Mass Analyzer (APM 3601) classifies particles by mass, based on the balance between centrifugal force and electrostatic force. This desktop unit classifies aerosol particles of 0.001 to 1000 femtograms.
The APM can be used in the following applications:
- Mass distribution measurements
- Particle density research
- Monodisperse aerosol generation
COMING SOON - Drift Tube Ion Mobility Spectrometer (DTIMS Model 3006)
The DTIMS performs high-resolution ion mobility measurement of large molecules and nanoparticles in the gas phase or within aerosol processes, such as combustion systems. The DTIMS couples an aspirating drift tube with a fast-response, condensation particle counter, achieving the following:
- Particle measurement range from 2.0 to >40 nm
- High resolution (Zp/ΔZp) >20 up to 10 nm
- Ultrafast measurement (<10 sec) for sub-10 nm aerosols, 60 seconds for up to 40 nm
Fast Condensation Particle Counter Model 3650
The 3650 has the fastest response time of any commercially available condensation particle counter on the market, with a 10-90% response time (~ 35 ms time constant (Ʈ) ~20 ms) and a 50% detection efficiency at 2.4 nm.
Black Carbon Monitor, Model 3130
The Black Carbon Monitor Model 3130 is a fully automated, continuous soot monitoring system that provides real-time measurement of light absorption by black carbon aerosols. It can be used in a variety of applications, including:
- The measurement of health hazards in ambient air

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
Kanomax NanoAerosol Generator Model 3250
The NanoAerosol Generator Model 3250 is a pneumatic-type nebulizer that produces an ultrafine aerosol. In addition to general aerosol research, the Model 3250 can be used in place of an electrospray generator for many applications due to the small particle size it generates.
Diluters & Conditioners
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).
An EPA-standard cyclone for removal of large particles from a sample stream.
