We establish a measurement system based on low atomic number absorption spectrum of fluorescence emission via the beamline station 08U1A of Shanghai Synchrotron Radiation Source, and explore the partial fluorescence yield (PFY) based on absorption method. The feasibility and applicability of this setup is verified on low Z elements in soft condensed matter and semiconductor areas. The research objects of CF4 gas and iodine methylamine lead (CH3NH3PbI3) verify the feasibility of PFY absorption spectroscopy. Then the low limit of sensitivity to sample concentration is determined.
