Dekati: Fine Particle Measurement Instruments - Bipolar Charge Analyser BOLAR

The Dekati® BOLAR™ can separately detect positively and negatively charged particles in five different particle size fractions. After the charge measurement, negatively and positively charged particles can also be analyzed enabling measurement of charge to mass ratio in different particle size fractions. This completely new kind of information is needed in the development of inhalable medicine and delivery devices; the positive and negative charge levels carried by particles can vary significantly between different inhaler devices depending on the materials used in the device, the design of the device, carrier and drug particles used in the device and operating conditions. Until now, the measurement of size classified bipolar electrical charge levels has not been possible, which makes the Dekati® BOLAR™ a completely unique tool for inhaler device development.

The two stage dilution system features unmatched versatility with applications reaching from automotive pre- and post after-treatment measurements to nucleation studies.

Dekati: Fine Particle Measurement Instruments - Mass Monitor DMM

DMM, Dekati® Mass Monitor, is a real-time measurement instrument for monitoring PM emissions from diesel and gasoline vehicles. Used either with a tailpipe sample conditioning system or existing CVS tunnel the DMM provides second-by-second information about vehicle PM mass and number emission. In addition to particle mass concentration, DMM also provides information on particle number concentration and particle size distribution (MMD and GSD).

Dekati SAC-65 Cyclone

Dekati® Cyclone is an EPA-standard cyclone for removal of large particles from a sample stream. The cyclone can be used in high temperatures due to its all-stainless steel construction. Dekati® Cyclone is manufactured according to EPA standard 201A. With standard isokinetic nozzles available as accessories, the Dekati® Cyclone is a highly durable addition to any sampling line where removal of large particles is needed.

Dekati Thermodenuder

Dekati® Thermodenuder is used to remove volatile and semivolatile compounds from aerosol sample in order to eliminate unwanted sample transformations e.g. in engine exhaust measurements. The volatile and semivolatile compounds are vaporized when they enter the instrument and then adsorbed into active charcoal which has been designed to the form of mats for ease of use. The Dekati® Thermodenuder is especially suitable for use with the ELPI+™ (Electrical Low Pressure Impactor) and the DMM (Dekati® Mass Monitor), also manufactured by Dekati Ltd, but can be used with any measurement device with a suitable flow rate.

Dekati: Gravimetric Impactor Line - DGI-1570 Gravimetric Impactor DGI

DGI-1570 (Dekati® Gravimetric Impactor) is a high sample flow rate cascade impactor designed for measuring gravimetric particle size distribution of particles < 2.5 µm. In a standard DGI setup particles are size classified into 5 size fractions with impactor stage cutpoints of 2.5, 1.0, 0.5 and 0.2 µm. If detailed information on the size distribution is not needed, some of the impactor stages can be removed from the DGI assembly. The impactor can e.g. be used without the 0.5 and 0.2 to stages to determine only PM2.5 and PM1.0 concentrations. The nominal sample flow rate though the DGI is 70 lpm which enables high sample yield even during short measurement periods. Typical measurement applications of the DGI impactor include engine emission measurements, air quality studies and other applications where high sample flow rate is needed.

Dekati: Gravimetric Impactor Line - Low Pressure Impactor DLPI

DLPI (Dekati® Low Pressure Impactor) is a 13-stage cascade low pressure impactor to determine particle gravimetric mass size distribution. The size classification in DLPI is made from 30 nm up to 10 µm with evenly distributed impactor stages and can be extended down to 30 nm with an additional back-up filter. In each size fraction the particles are collected on 25 mm collection substrates that are weighed before and after the measurement to obtain gravimetric size distribution of the particles. A chemical analysis of the size classified particles can also be performed. Other DLPI characteristics include low inter-stage wall-losses and robust yet easy-to-use operation. The rigid stainless steel construction of the DLPI makes it suitable for a wide variety of applications including power plant and vehicle emission measurements, engine blow-by measurements, air quality studies and pharmaceutical inhalation aerosol device testing.
