Contagem de partículas em laboratórios farmacêuticos ou de ciências biológicas

• Wehn sampling a room to do a room qualification with the Lasair II, at what height should the samples be taken? Close to the floor or at working height?
• When performing a room-qualification for 0.5 micron as well as for 5 um particles: In order to avoid doing it twice - one should do it at 5um. Correct?
• During revalidation, is it mandatory to carry out particle monitoring for 3 consequitive days in laminar air flow unit & as well as in area qualification ?
• Which is the suitable classification for clean rooms in hospitals? Is there any classification that gives the category of ISO for rooms such as "operating theatres", "isolation room", "intensive care room", etc?
• How many locations do we need for ongoing routine particle count tests?
• We are setting up a manufacturing facility which will have areas specified with particle concentaration limits as per ISO 8. The system is ready for validation. Which guidelines should be followed before starting the particle count tests.
