we report development of a data acquisition system for XAFS(X-ray absorption fine structure) analysis of samples of extremely low concentrations on the BL14W1 beamline at Shanghai Synchrotron Radiation Facility(SSRF).The system includes an XFlash 5040 silicon drift detector
ion chamber
amplifier
ADC etc.Labview software was used to write the data acquisition program.Fluorescence K-edge XAFS spectra of FeCl

aqueous solution containing 5.0μg/g Fe and a 1nm Ni thin film were used to demonstrate performance of the system. The test results indicate that the data acquisition system of BL14W1 XAFS beamline is capable of measuring samples of extremely low concentrations.
