Abstract
An apparatus for analyzing a fluid of volume V includes a filter having a filter surface or area A, the filter being capable of allowing the fluid to flow through the filter surface. The fluid's volumetric flow density, averaged over the filter surface, is jmean. The apparatus further includes a scanner for scanning the filter surface with a scan rate B. The area A is optimized based on the volume V, the scan rate B and the volumetric flow density jmean to minimize the sum of filtering time and scanning time. Instead of one filter, at least two filters may be used each having a different area A. The apparatus also includes a mechanism for selecting one of the filters and placing the selected filter in an operating position, where the scanner scans the filter surface face of the selected filter.
