ACTRIS

Calibration of the instruments according to ACTRIS and TC recommendations

QA/QC according to ACTRIS reccommendations and operation guidelines

Measurement guidelines for NFs for instruments dealing with aerosol physical properties (for observational and exploratory platforms)

This service is to calibrate nano-mobility particle size spectrometers, ion spectrometers or nano-CPCs in the size range of ca. 1-10 nm in mobility diameter

Training and capacity-building (possibility to tailor the training depending on the interests of the participants, e.g. usage of high-resolution-DMA calibration setup, operation of PSM or NAIS, sampling of sub-10nm particles)

Provision of two detailed measurement guidelines for NFs. One for the observational platforms, one for the exploratory platforms that will be developed for current and updated for future needs.

The performance of NFs measuring elemental composition of particulate matter samples is evaluated based on: QA/QC outputs, participation in inter-laboratory comparisons, calibration and training workshops, and effective data reporting to ACTRIS DC. Service available to external users

Provision of up-to-date guidelines for measuring the elemental composition of aerosols.

Quality Assurance (QA) and Quality Control (QC) check of compliance with ACTRIS recommendations (instrument type, participation in calibration workshops, operation according to SOPs, operator qualification,  scope of applicability).  Check of measurement data plausibility.

The performance of methods and instruments for measuring the elemental composition of aerosols is evaluated against distributed reference standards.
