Keywords: scanning electric mobility particle size spectrometer, nanoparticle Analyzer, aerosol particle size analyzer, ECAC, calibration certificate
With the continuous development of the nano field, nanoparticles have attracted much more attention in scientific research projects such as optics, electricity, biology, and environment. The differential electrical mobility classification and analysis of aerosol particles is used in the measurement of nano-to-micron aerosol particles in the field of environmental monitoring. Based on its simple physical principles, it has become an important part in the field of aerosols, such as: aerosol instruments, aerosol-based material production, semiconductor industry pollution control, atmospheric aerosols, engineered nanoparticle characterization, etc. At the same time, electromobility fractionation of charged particles produces monodisperse particles of known particle size that can be used to calibrate other instruments.
Recently, Palas® SMPS Scanning electric mobility particle size spectrometer passed the inspection and certification of the National Institute of Metrology, China (NIM), and obtained the calibration certificate from NIM. Earlier, SMPS has passed the test of European Center for Aerosol Calibration and Characterization (ECAC) testing institute TROPOS. The results also show excellent parallelism data.
Accurate sizing and counting
The calibration of NIM refers to the calibration regulations of JJF 1864-2020 aerosol particle size spectrometer. Multiple calibration items are tested from particle size measurement indication error, particle technical efficiency and counting repeatability. Take the measurement of particle size measurement indication error as an example: The standard value of particle size is 72.1nm, the measured value is 74.989nm, and the indication error is 4.0%. In terms of particle counting efficiency: the standard value of number concentration is 1014 particle / cm3, the measured value is 1010 particle / cm3, and the counting efficiency is 99.6%. As shown in the figure below, the NIM calibration results report demonstrates two characteristics of the Palas® SMPS Scanning electric mobility particle size spectrometer: 1. Accurate sizing; 2. Accurate counting.
Earlier test results of SMPS at ECAC testing institute TROPOS also showed good parallelism data. As shown in the figure below, the linearity of the 10 sets of instruments submitted by Palas® were all <±5%. fully compliant and superior to CEN/TS 16976. Palas® is able to provide customers with standardized, stable and excellent service, which provides support for scientific research, quality control and other fields.
Instrument brand that conforms to the specification
Palas® products can meet JJF 1562-2016 “Condensation Nucleus Particle Counter Calibration Specification”, JJF 1800-2020 “Aerosol Photometer Calibration Specification”, ISO 15900:2009 “Differential Electromigration Method for Measurement of Aerosol Particle Size Distribution”, JF 1864-2020 “Calibration Specification for Aerosol Particle Size Spectrometer” and other relevant specifications to assist measurement and testing experts to complete the calibration of particle testing equipment. Palas® SMPS Scanning electric mobility particle size spectrometer has been used by metrology institutes for the calibration and testing of respiratory protection filter efficiency testers, etc., providing technical support for various detection and calibration tasks.
Palas® SMPS Scanning electric mobility particle size spectrometer
The Palas® SMPS, is an advanced nanoparticle measuring system that measures aerosol particle size distributions from 4nm to 1200nm. It provides not only accurate and reliable particle size analysis and counts, but also ensures high resolution in up to 256 size channels.
