Dekati® Low Pressure Impactor DLPI
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.
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.
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®+.
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.
