Our Testing Facility

Our dedicated aerosol engineering and testing staff can assist you during the design, confirmation testing, product improvement, and validation stages of pre production. We offer field staff support, a fully equipped laboratory with sampling and particle analysis capabilities, and full technical reporting with secure data archival.

AlburtyLab performs field testing for determination of ambient (indoor and outdoor) aerosols and controlled (aerosol chamber and wind tunnel) tests. Field sampling is performed using high volume air samplers, virtual impactors, laser particle counters, aerodynamic particle sizers, optical mass concentration instrumentation, biological samplers, and custom/developmental samplers. Chamber tests are used to determine Sampling Efficiency, Collection Efficiency, Aspiration Efficiency, and Transmission Efficiency. Chamber tests are performed by aerosolizing the particles under test in a controlled, advantageous manner and concentration in a 2300 liter environmentally-controlled chamber. Samples are either withdrawn from the chamber for observation or are sampled directly inside the chamber, depending on the need.

Aerosol Particle Generators
Controlled-flow tube system (Henderson Apparatus) equipped with a TSI vibrating orifice aerosol generator (VOAG), PITT-3, TSI Small Scale Powder Disperser.
Anderson 6-stage viable impactor, AGI-30 impingers, high volume air samplers, virtual impactor.

Aerosols are captured for analysis using 47mm dry filter holders. The Field Station laboratory is equipped for BSL-2 and pharmaceutical/chemicals operation, and operates under negative pressure with HEPA filtration.

Particle Analysis Equipment
Supporting equipment available in the labs includes high-precision balances, a fluorometer, spectrofluorometer, spectrophotometer, and Coulter counter (for liquid particle analysis), as well as a gas chromatograph (GC/FID). The laboratories house two drying ovens (300º C), a high-temperature muffle furnace (1200º C), incubator, centrifuge, and other small equipment such as manometers, pumps, variable transformers, differential pressure gauges, micropipettors, mixers and glassware needed for the conduct of experiments and testing.

Reference Methods
EPA, ASTM, ECBC and other reference methods are used as appropriate. GLP studies are conducted by trained and certified staff.

Viability Testing
Calculation of CFU/liter air of organisms disseminated and captured and are used to calculate retention factors, concentration factors, and sampling efficiency. Inert particles such as Polystyrene Microspheres, Ammonium Fluorescein, Ovalbumin, and Oleic Acid are disseminated and captured to calculate retention factors, concentration factors, and sampling efficiency.
