Fluorescence preselection of bioaerosol for single-particle mass spectrometry

Stowers, M.A. (author), Van Wuijckhuijse, A.L. (author), Marijnissen, J.C.M. (author), Kientz, C.E. (author), Ciach, T. (author)

We have designed, constructed, and tested a system that preselects the biological fraction of airborne particles from the overall aerosol. The preselection is based on fluorescence emission excited by a continuous 266 nm laser beam. This beam is one of two cw beams used to measure the aerodynamic particle size of sampled particles. The intention...

Method and device for detecting and identifying bio-aerosol particles in the air

Stowers, M.A. (author), Wuijckhuijse, A.L. (author), Marijnissen, J.C. (author), Kientz, C.E. (author)

In a method for detecting and identifying bioaerosol particles in the air, the bioaerosol particles in a particle stream are selected in an ATOFMS (aerosol time-of-flight mass spectrometer) by means of fluorescence techniques, and only the selected bioaerosol particles are ionized, for instance on the basis of MALDI (matrix-assisted laser...

Method of the dosed application of a liquid onto a surface

Moerman, R.J. (author), Frank, J. (author), Marijnissen, J.C. (author)

The invention relates to a method of the dosed application of a liquid onto to selected portion of the surface of a substrate (A) by means of spraying under the influence of an electric current. According to the invention the liquid is fed at a flow rate between 0.01 pl/s and 1 ml/s to a distal tip ( 3 ) of a capillary ( 1 ) having an inside...

particulate matter from a gas stream. Rational design of the filtration process should be based on reliable prediction of the effluent concentration and pressure drop for a given set of operating conditions. Moreover, both of these main filter parameters vary in time when a fibrous structure becomes more and more loaded with deposits. Usually,...

Method and apparatus for measuring particle size at low concentration

Marijnissen, J.C.M. (author), Willemse, A.W. (author), Roos, R.A. (author)

Described is an improved method for measuring the particle size of ultrasmall particles (111) which are suspended in a fluid. Laser light (121) is scattered by the particles, and the scattered light (122) is received by a light detector (131) which provides an electrical measuring signal (Sm) which is representative of the intensity of the...
