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
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.
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
