A method of treating a liquid sample having microbiological target species therein to concentrate the species and collect lysate is disclosed. The liquid sample comprises non-target microbiological particles, inorganic particles, and microbiological target species. The liquid is passed through a prefilter medium to allow the target species to pass through as filtrate and retain non-target microbiological products and inorganic particles thereon. The filtrate is contacted with a main filtration medium adapted to retain the target species thereon as retentate. The retentate is lysed to form a lysate containing target material that was enveloped within the microbiological target species. The microbiological species may comprise cell containing or viral material. Target materials comprise intracellular nucleic acids, or in the case of viral sampling, nucleic acids encased within the protein sheath or coating of the virus.

Process for concentrating and processing fluid samples

A power generation system comprises a power source, a transformer module for converting a low voltage from the power source into a higher voltage, and a voltage-multiplier module for amplifying higher voltage from the transformer module. The transformer module comprises a number N of transformer units. Each transformer unit comprises at least one transformer, and each transformer comprises a magnetic core, a primary winding, and a secondary winding. Primary windings of the transformers in the transformer module are electrically coupled in parallel to the power source, secondary windings of the transformers of each transformer unit comprise a pair of output terminal, and N is equal to or greater than two. The voltage-multiplier module comprises the number N of multipliers. Each multiplier module comprises a positive and a negative input terminal, and a positive and a negative output terminal. Positive and negative terminals of each multiplier are electrically coupled to the positive and negative output terminals of a corresponding transformer unit, and positive and negative output terminals of the multipliers are connected in series.
