This article describes an environmental monitoring data study for clean rooms. Two
parameters were compared in order to investigate the possibility of correlation between …

We present, in detail, the (microbiological) environmental monitoring programme for
cleanrooms that is in use at the RIVM†. The parameters that are measured are: Total …

A comparative study was done among available assessment methods to measure airborne
viable particles in controlled rooms. Active methods were compared (sieve/nozzle impactor …

Hazard Analyses and establishing of Critical Control Points (HACCP) using a method with
Limitation of Risks, known as the LR Method are described. This method has a concept …

This paper presents results from a comparative study of different impaction air samplers
under simulated operational conditions in a controlled environment. Furthermore …

Aims To assess the different operational states within a biopharmaceutical grade clean
room, using a rapid microbiological method. The method was a novel system, based on …

Ambient particles, potentially carrying microbial contaminants (viable particles), and
nonviable particles can spread from surfaces to the surrounding air volume of a proposed …

By means of sophisticated analytical techniques, accurate research results can be obtained
even when concentration values are very low. Work must be performed in a contamination …

Introduction. Recent discoveries in cell therapy research present new opportunities for
cellular products to be used to treat severe, and as yet incurable, diseases. It is therefore …

The purpose of this presentation is to describe the theoretical relations for the dispersal of
airborne contaminants and to illustrate the validity of these equations occuring during factual …
