Durag Group GRIMM SMPS+C 5420 Scanning Mobility Particle Sizer and Counter

The GRIMM SMPS+C 5420 is a 19-inch scanning mobility particle sizer and counter designed for unattended 24/7 real-time monitoring of ultrafine particles (UFP) in ambient air. The system combines electrostatic classification in a DMA with condensation particle counting to provide high-resolution particle size distribution data for ambient air monitoring and research applications. DURAG offers the platform as the SMPS+C 5420 CEN with a size range of 10 nm to 1,090 nm for compliance with CEN/TS 17434:2020, or as the standard SMPS+C 5420 with M-DMA for a size range of 5 nm to 350 nm.

The SMPS+C 5420 is built for precise nanoparticle sizing and counting using an n-butanol based CPC with exchangeable Vienna Reischl Type DMAs. DURAG highlights benefits including harmonized UFP sizing and counting, low particle losses, high size resolution, and easy integration into measurement stations. Integrated pumps for sample and sheath air, critical-orifice flow control, and long-term butanol and condensate tanks support extended unattended operation for ambient monitoring networks and research environments.

Available in Canada through Westech Industrial, the GRIMM SMPS+C 5420 is a strong fit for customers who require detailed ultrafine particle size distribution monitoring as part of ambient air quality programs, research studies, or long-term environmental particle monitoring projects.

PRODUCT FAQ's

What is the GRIMM SMPS+C 5420 used for?
The GRIMM SMPS+C 5420 is used for real-time ultrafine particle size distribution monitoring in ambient air. DURAG lists applications including regulatory monitoring, governmental networks, ACTRIS-compliant use, fundamental aerosol research, environmental aerosol research, nanotechnology process monitoring, and studies on atmospheric nucleation.
What is the difference between the SMPS+C 5420 and the SMPS+C 5420 CEN?
The standard SMPS+C 5420 uses the M-DMA for a size range of 5 … 350 nm, while the SMPS+C 5420 CEN uses the L-DMA for a size range of 10 … 1,090 nm and is intended for compliance with CEN/TS 17434:2020.
How does the SMPS+C 5420 measure ultrafine particles?
The system uses electrostatic classification in a DMA and detection in a condensation particle counter (CPC) to measure particle size distribution as dN/dlogD (1/cm³). This combination allows precise sizing and counting of ultrafine particles in ambient air.
Is the SMPS+C 5420 suitable for unattended long-term monitoring?
Yes. DURAG states that the SMPS+C 5420 supports unattended 24/7 operation for three weeks or more, with integrated pumps, long-term butanol and condensate tanks, and no external vacuum required.
Can Westech help assess whether the SMPS+C 5420 is the right fit for an ambient air particle monitoring project?
Yes. Westech Industrial can help customers in Canada review project goals, monitoring requirements, and installation needs to determine whether the GRIMM SMPS+C 5420 or SMPS+C 5420 CEN is the right fit for their ambient air monitoring program.
