Matrix Certified Reference Materials


Code ERM-CZ110, Fine dust (PM2,5-like)
A new Certified Reference Material simulating airborne particulate matter (PM2.5) has been developed by the JRC.
It is available now for laboratories analysing the composition of airborne particulate matter in the frame of air quality monitoring as required in EU legislation.
Airborne particulate matter is a major problem in many densely populated areas of the world. This pollutant is a mixture of particles of different size and composition, originating from different sources.
The finest fraction of these particles, the so-called PM2,5,, is notoriously dangerous because it can penetrate deep into the lungs and may pass into the bloodstream causing respiratory problems and premature death. In response, the European Union has developed an extensive legislation which establishes health based standards and objectives for a number of pollutants including PM2,5. The Ambient Air Quality Directive 2008/50/EC, in particular, also requires EU Member States to make additional measurements on the chemical composition of PM2,5. The chemical species that have to be measured are water-soluble ions (Na+, K+, Ca2+, Mg2+, NH4+, Cl–, NO3– and SO42–), elemental carbon (EC) and organic carbon (OC). The European Committee of Standardization has recently developed standard methods for the measurements of water-soluble ions as well as for OC and EC in PM2,5 (EN 16913:2017 and EN 16909:2017, respectively).
To ensure accuracy and comparability of measurement results, the use and the analysis of Certified Reference Materials is required. The new certified reference material ERM®-CZ110 satisfies this need and will support EU Member States and air quality laboratories to comply with the EU legislation for water-soluble ions measurements.

Our partner myStandards GmbH is a specialist for turning your sample matrix into a homogenous pressed pellet applicable as a reference material for a large variety of microanalytical techniques: 
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)
Laser-induced breakdown spectroscopy (LIBS)
Micro x-ray fluorescence spectroscopy (µXRF)
Secondary-Ion Mass Spectrometry (SIMS)
The pressed pellet is made of nano-particulated powder (d50 of 250 nm) and does not contain any binding agents, making it extremely pure and homogeneous. 
Depending on the microanalytical technique the pressed pellets can be processed in Ø 5, 10, 13, 20 mm and can also be ordered with a mount made out of polymer or aluminium.
