A particulate collection system, including a particulate matter analyzer and collecting filter, provides a method of analyzing and collecting samples from fluids, such as collecting particulate matter from air. A mass measuring unit and composition analyzing unit can be provided for either simultaneous or immediately consecutive measurements within a single instrument. The filter material can have an antistatic electricity characteristic and can be impregnated with reference material to enable calibration of the composition analyzing unit.

This invention provides an apparatus for measuring ozone in which interference effects of SO.sub.2 are intended to be reduced. This invention comprises a reference gas line for generating reference gas with ozone removed by allowing the sample gas to pass through the ozone decomposer with silver wool used as a catalyst, a sample gas line for introducing the sample gas as it is, an ozone analyzer to which the reference gas line and the sample gas line are connected via a selector valve and which measures the ozone component in the sample gas by introducing the reference gas and the sample gas alternately at specified intervals, and a temperature controller installed to the ozone decomposer for setting the catalyst reaction temperature to a range from 100 to 130.degree. C.

A method and apparatus for analyzing fluid by a multi-fluid modulation mode is characterized by subjecting a plurality of sample fluids (which may be different or a single sample fluid divided into a plurality of systems) to a fluid modulation by reference fluids at various frequencies, respectively. An analytical portion provided with only one sensor is simultaneously and continuously supplied with the respective sample fluids. An output signal from the sensor in the analytical portion is divided into signal components of the respective modulation frequencies for the respective sample fluids to rectify and level, whereby obtaining analyzed values about the respective sample fluids is achieved.
