Update of ELPI and DMM instruments from Dekati

Since early 2009, the new version of the DMM instrument (DMM-230a) offers real-time particle number concentration measurements in addition to previous features such as mass concentration and size information (mass median diameter and geometric standard deviation). Since spring 2009, the AK protocol can also be provided as an option for instrument control (e.g. start, stop, flush, etc.) and data acquisition to the host computer. Older DMM units can be upgraded to the DMM-230a version.

A 16-channel PCI board for analogue output of ELPI measurement data is now available for much more convenient data acquisition by external measurement systems. For the “outdoor air” OELPI, used in ambient air monitoring, an USB memory  stick can now be used for simpler data transfer from the instrument to other data storage.

New Topas Aerosol and Dilution System (ADD 356)

To avoid contamination in hospital operating rooms, a laminar clean air flow is applied to the operating table. For verification of this system, a defined test aerosol is distributed at six different positions according to the German DIN 1946-4 and Swiss SWKI 99-3 standards. The Aerosol Distribution and Dilution System ADD 536 was designed to fulfil these requirements. Many other applications, such as simultaneous calibration and alignment of particle counters are also possible. More information is provided in the ADD 356 brochure.

Grimm EDM 180 passes equivalence test

The standard 19" rack Environmental Dust Monitor (EDM) of the series 180 have been tested in Europe at different sites in Austria and fulfilled the requirements in accordance to the European regulation for PM10 and also PM2,5. Therefore, this is the first unit of this optical kind able to report officially both values in 1 min intervals. In addition, this version has also the capability to present the PM1,0 value as well as the Tc Value (Total Count, a new way to explain the aerosol distribution in the atmosphere). This will help in the understanding of the mass concentration and is a continuous measurement level of the air (aerosols). With the documentation from the Austrian tests mentioned, we hope to receive an approval in Sweden also in the near future.

ExIS starts co-operation with Pegasor

In the summer 2009, ExIS and Pegasor initiated a co-operation. Pegasor is based in Tampere, Finland. The Pegasor Particle Sensor (PPS) is based on novel technology. Exhaust is sampled by using a built-in ejector. The operating principle of PPS is based on particle charging and electrical detection. PPS does not collect particles and the charger is shielded by clean air, implying an extremely long time between cleaning. Its sensitivity is high enough for measurements after a particle filter (DPF). PPS has a potential sampling rate of up to 100 Hz. Besides stand-alone operation, PPS will be used in the future as a component in integrated measurement systems in, e.g., for particle number measurements according to PMP requirements and for on-board PM measurement systems.

Interesting results with the Dekati DMM instrument in the heavy-duty PMP programme

Phase 3 of the UN-ECE Particulate Measurement Programme (PMP) comprise an inter-laboratory correlation exercise. Besides mass and particle number measurements, two additional instruments, i.e. the AVL Micro Soot Sensor (MSS) and the Dekati DMM, were used to characterize particle emissions. Since MSS measure soot mass and DMM measure solid particle mass, the results are complementary and thus, can provide new insights. Over the cold start WHTC test cycles, both instruments measured mass concentrations ~10% of those determined gravimetrically. This fraction is similar to that determined for cold NEDC tests during the light-duty inter-laboratory correlation exercise. In the hot start test cycles, DMM shows that the contribution of solid particles was only 0,5% of the gravimetrically determined PM, i.e. volatile particle mass contributed to total PM by ~99,5%. For more details we refer to the draft report and the summary of DMM tests compiled by ExIS. Links to the mentioned documents are provided below.

Dekati DEED new golden standard in PMP

A Volatile Particle Remover (VPR) system based on the Dekati Engine Emission Diluter (DEED) has been announced to be the “golden” standard for the UN-ECE Particulate Measurement Programme (PMP) VPR calibration. The calibration study will consists of round robin measurements at several test laboratories in Europe. The low particle losses of the DEED in comparison to all other dilution systems is certainly a significant advantage for VPR calibration. A summary of the VPR test results is provided by ExIS in a separate document, accessible below and in addition, a link to the draft heavy-duty PMP report is also provided. Further information on this topic is also found under the heading about the DMM tests below.

The Pegasor PPS sensor has been launched

The Pegasor Particle Sensor (PPS) has been launched. Production started in March and the first batch of some 10 sensors was delivered to various customers by end of March. Demonstrations at customer sites have already been made and more of these activities are planned during spring/summer 2010. Please contact us if you are interested for a demonstration.

PPS measure directly in raw exhaust and thus, it need no external sampling and dilution. The simplicity and robustness of the PPS has been specifically developed to provide environmentalists, hygienists, and authorities to develop realistic management strategies. At a sampling rate of up to 100 Hz, PPS provides exceptional time response.

The Pegasor particle sensor operates by electrostatic charging of particles passing through the sensor and then measuring the current caused by the charged particles leaving the sensor. The flow-through design keeps the sensor clean for extended operation and low maintenance. The particle charger is only exposed to clean air. More information is provided in the brochure and our latest newsletter.

New Topas instruments

Three new instruments from Topas have been launched.

PAP 610. The Process Aerosol Photometer Topas PAP 610 was developed for in-situ-concentration measurement of blow-by aerosols. This measuring instrument is an addition to the Gravimetric Measurement System GMS 141, which is also provided by Topas. The GMS 141 is used for calibrating the PAP 610.

GMS 141. Oil mist separators are basic components of a crank case ventilation system. The Topas gravimetric measurement system GMS 141 allows the comfortable detection of oil content in blow-by after oil mist separators with a filter blank sheet or filter cartridge directly on engines or engine test stands. The measuring device combines a simple and rugged assembly with an economic low-cost manual application and handling. The device is controlled via visualisation in a web browser.

MBP 116. Performance of filter media is essentially defined by parameters such as differential pressure, gravimetric filtration efficiency and dust holding capacity. The Topas Manual Filter Media Test Rig MBP 116 can be applied to determine these filter parameters at flat sheet materials. This test rig has been designed as universal testing equipment. It combines a simple and robust setup with a manual and therefore cost efficient handling and operation.

Car brakes just as big an environmental problem as studded tyres

Research at the Royal Institute of Technology (KTH) shows that particles from vehicle brakes are so small that they could cause the same respiratory diseases as studded tyres. Car brakes contribute as many particles as studded tyres and the car’s exhaust gas emissions do. The particles from a car's brakes are less than 10 µm in size and even go down to nano sizes, which means that they can enter the human body. Particles are generated both during braking and when brakes are not used, since brake pads rest against the discs to keep them clean in the latter case. To date, five publications in Scientific Journals and at International Conferences have been made from this research.

In the research at KTH, several particle instruments from ExIS partner Grimm Aerosol has been used to generate test data.

More information is provided in the press release (both in English and Swedish) from KTH (25 May).

Dekati’s new ELPI+ instrument gain much interest at the IAC conference

The new ELPI+™ (pronounced ELPI plus) instrument from Dekati was launched at the International Aerosol Conference (IAC) in Helsinki on Monday, August 30. The interest from the conference delegates is great and the Dekati booth has hardly ever had so many visitors before. Two scientific papers on the ELPI+ will be presented at IAC on Thursday and Friday, respectively.

Construction of the ELPI+ has been simplified, yet maintaining the unit as robust as the previous ELPI model to endure operation even in harsh conditions. At the same time, the weight of the ELPI+ unit has been reduced to 22 kg, making it more easily transportable. ELPI+ has more measurement channels, improved sensitivity, higher time resolution (10Hz) and several new features compared to the “old” ELPI. The impactor has fewer parts and is much more convenient to handle and easier to clean.

During the development phase of more than two years, ELPI+ has been field tested thoroughly by Dekati. This has been accomplished by conducting several measurement campaigns, where ELPI+ and the previous ELPI have been used in parallel.

ELPI+ is now ready for ordering. The first units will be delivered by end of 2010. Delivery time is currently about three months but will be shortened when production is ramped up. Under a transitional period, the “old” ELPI will be produced in parallel with ELPI+. Supply of spares and support for the old ELPI will continue for many years to come.

Grimm EDM 180 approval in Sweden as equivalent method for measuring PM10 and PM2,5

So called “reference methods for sampling and measurement of particles smaller than 10 and 2,5 micrometres respectively (PM10 and PM2,5) according to Swedish and EN/ISO standards (SS-EN 12341:1998 and SS-ISO 10473:2000) imply that particles pass through a selective inlet and are collected on a filter for weighing. This is a labour-intensive and complicated method that, in addition, does not provide any opportunity for real-time measurements. In order to achieve real-time measurements of PM10 and PM2,5 (and other size classes), gravimetric measurements cannot be made but other measurement principles must be used. Therefore, instruments that do not use the reference method are classified as an “equivalent method” by the Swedish Environmental Protection Agency (SEPA). In order to obtain an approval for an instrument as equivalent method, comprehensive correlation measurements and documentation of the results are necessary.

Our partner Grimm Aerosol in Germany has developed an instrument, “Environmental Dust Monitor” (EDM 180 and similar instruments in this family), which previously has obtained approvals for measurement of air quality in several countries in, among others, Europe. Based on an assessment conducted by the Reference Laboratory for urban air at the Department of Applied Environmental Science at the Stockholm University, the Swedish EPA is now recommending the EDM 180 as an equivalent method to the reference method for control of environmental quality norms for ambient air according to NFS 2010:8.
