05/11/08 Development of a confinement solution for laboratories and small industrial applications Presentation of FAURE Ingénierie’s safety cabinet for nanostructured particles : The PSPN P. BOMBARDIER / J.M. REINWALT 28/10/2008 2 professions to be successful Conception & realization of clean controlled environment Pharmaceutics High tech fields !THE COMPANY Electronics Food & other related industries Engineering !NANO ACTIVITIES Hook-up, revamping, etc. ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT Solution development and optimization (R&D) !PSPN DESCRIPTION Customers training !PERFORMANCE TESTING France, !EVOLUTION Switzerland, Canada, Metrology Performance/ compliance tests / Fluids quality monitoring Morocco, Singapore Contamination expertise Sensors calibration Page 2/12 28/10/2008 Activities in the field of Nanotechnology !THE COMPANY • Conception of laboratories dedicated to nanoparticles handling. !NANO ACTIVITIES ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT • Conception of safety cabinet and exhausting systems. !PSPN DESCRIPTION !PERFORMANCE TESTING • Qualification and performance test of controlled environment dedicated to nanoparticles. !EVOLUTION • Audit, staff training, development of methods. Page 3/12 28/10/2008 For What ? !THE COMPANY Safe handling of dry powders and wet suspension of nanoparticles or nanostructured particles. !NANO ACTIVITIES ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT Protection of the working surface from outside contamination. !PSPN DESCRIPTION !PERFORMANCE TESTING Protection of the outside environment. !EVOLUTION Simplicity of use and cleaning for multi-user environment. Page 4/12 28/10/2008 How-to ? On the basis of microbial safety cabinet, the PSPN improve : !THE COMPANY !NANO ACTIVITIES • filtration efficiency • security survey systems ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT • cleaning ability • possibility of extension and modification of the work surface. • testing operations (injection and test port implemented) !PSPN DESCRIPTION • the safety during operations on recycled air filters. !PERFORMANCE TESTING !EVOLUTION Page 5/12 28/10/2008 How-to? A computational fluid dynamic (CFD) software is used to define the internal geometries : • Holes position and size around the useful work surface. !THE COMPANY !NANO ACTIVITIES • Airflow behavior with •large equipment inside (weighing machine, etc…). •an operator in front of the PSPN. ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT !PSPN DESCRIPTION •an external airflow (horizontal or vertical). • Definition of the good adjustments for the air speed (blowing and aspiration) and security limits for these parameters. !PERFORMANCE TESTING !EVOLUTION Page 6/12 28/10/2008 How-to ? Homogeneity in the entrance area !THE COMPANY !NANO ACTIVITIES No cross-contamination between coupled PSPN ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT Contamination quickly evacuated !PSPN DESCRIPTION !PERFORMANCE TESTING !EVOLUTION Page 7/12 28/10/2008 Technical choices The main characteristics are : • ISO 5 particulate class. !THE COMPANY • Stainless steel conditioned to reduce the particle adherence. !NANO ACTIVITIES • Coupled solutions with possibility to add fluid tubing inside. • 3 worktop (tank-like ; perforated or marble made for stability). ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT !PSPN DESCRIPTION !PERFORMANCE TESTING • 3 ULPA filters to obtain a full containment of nanoparticules. • Individual selection of filters for the best blowing homogeneity. • High cleanliness demanded for the delivered systems. • Sensitive alarm systems (inside overpressure survey and filters head loss indicators). !EVOLUTION High safety level Page 8/12 28/10/2008 Qualification of prototype !THE COMPANY !NANO ACTIVITIES ! PSPN CABINET OBECTIVES !THE PSPN CONCEPT !PSPN DESCRIPTION !PERFORMANCE TESTING !EVOLUTION The special following tests where passed successfully : • Conformance with the objective of 0,0025% max leak level for all particle sizes (5 to 300 nm). The filters and the whole structure were tested. • Nanoparticles emitted inside are not detected outside of the front access (tested with carbon nanoparticles, a CNC and a SMPS). • The value and homogeneity of air speed is tested inside the PSPN and in the entrance area to verify that we respect the criteria ± 20% around the mean value. Page 9/12 28/10/2008 Qualification of standard equipments !THE COMPANY The standard performance test include : !NANO ACTIVITIES • Max outside airflow < 15 cm/s. ! PSPN CABINET OBECTIVES • Air speed adjustment and homogeneity testing. !THE PSPN CONCEPT !PSPN DESCRIPTION !PERFORMANCE TESTING !EVOLUTION • Leak test (with 0,3 µm particles) of filters and structure. • Cleanliness class inside and outside the PSPN. • Alarm set off when a default is triggered. • Absence of any retention zone inside (fog test with CO2 + H20). Page 10/12 28/10/2008 Evolution To satisfy all needs we propose the following version : !THE COMPANY !NANO ACTIVITIES ! PSPN CABINET OBECTIVES • A simple extraction hood with the same safety level as the first PSPN. • A cabin-like extended version to protect large operations. !THE PSPN CONCEPT !PSPN DESCRIPTION Possible adaptations : • Fluid supply. !PERFORMANCE TESTING !EVOLUTION • Small sink for liquids. • Special worktop for vibrating systems.
