White Paper: Gravimetric Analysis in Emissions Testing
Authors: Dr. Thomas Pertsch, Dr. Holger Densow | Last updated: May 2021
Overview
Diesel engines generally emit less CO2 than combustion engines, but they emit more nitrogen oxide and particulates. The danger to human health posed by these extremely small particulates has led to a significant reduction of regulatory limits on particulates emissions in the last decades.
Tighter limits on particulates emissions translate into the need for increasingly sensitive detection methods to reliably determine the smallest quantities of particles. Gravimetric measurement has become the standard method of legal exhaust measurement and is only method which offers both direct traceability and calibration.

Key Takeaways
- With gravimetric analysis, a sought constituent is converted into a substance of known composition that can be separated from the sample and weighed.
- The Sartorius Cubis II ultra-microbalance, with readability of 0.1 micrograms, is suitable for applications requiring extremely accurate measurements.
- The Sartorius Cubis II ultra-microbalance, particularly suited for gravimetric filter-weighing in emissions testing, but it is also adaptable to various other analytical and research applications requiring precise weighing
