An analysis method of performing an analysis on a sample containing a first substance and a second substance that has an influence on an analysis of the first substance in regard to a concentration of the first substance, includes performing an analysis on the sample in regard to the concentration of the first substance to obtain sample analysis data, and deriving a result of analysis in regard to a concentration of the first substance based on the sample analysis data and adjustment information that is set based on the influence.

Disclosed herein are integrated preparation and detection devices for studying biomass-burning aerosols, where the devices include a micro-fluidized bed reactor (MFBR), a transmission line, and an on-line detection unit that are connected in sequence. The MFBR may include a pyrolysis reactor and a pyrolysis furnace; the pyrolysis reactor may include a thermocouple, an introduction tube, and quartz sands; the on-line detection unit may be an on-line photoionization mass spectrometer; and the photoionization mass spectrometer may include a laser desorption system, a laser ionizer and a light energy ionizer. Devices of the present disclosure are beneficial to retain the original state of aerosol particles, and the fixed MFBR can realize rapid pyrolysis of a biomass due to its high and stable heat conduction efficiency, which is beneficial to studying the formation mechanism of aerosol particles.

A pyrolysis product library formed from a plurality of groups of predicted mass spectra corresponding to a plurality of resin candidates is created using a prediction model. An information processing unit generates a plurality of measured mass spectra corresponding to a plurality of compounds generated due to pyrolysis of a resin sample. Next, the information processing unit searches through the pyrolysis product library based on the plurality of measured mass spectra, to thereby judge one or a plurality of contained resins contained in the resin sample.
