SEC-SAXS was performed at 25 °C using the following parameters: Shodex Kw-403 analytical SEC column; Flow rate: 0.2 mL/min; Sample injection concentration: 8 mg/mL; Injection volume: 45 μL. The data were collected through the SEC peak of the sample as a series of 29 x 3 second exposures. Each unsubtracted data frame was normalised to the intensity of the transmitted beam and radially averaged and the scattering of an appropriate solvent-blank was subtracted. The resulting subtracted frames were scaled and averaged to generate the final SAXS profile displayed in this entry.","tags":[],"intensity_unit":"arbitrary","experimental_mw":33.825,"experimental_mw_error":null,"guinier_i0_mw":null,"guinier_i0_mw_error":null,"porod_mw":29.0,"porod_mw_error":null,"pddf_i0":0.001541,"pddf_i0_error":0.0001,"guinier_i0":0.001574,"guinier_i0_error":1.2e-05,"pddf_rg":2.484,"pddf_rg_error":0.02,"guinier_rg":2.562,"guinier_rg_error":0.033,"pddf_dmax":7.74,"pddf_dmax_error":null,"porod_volume":43.0,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":21,"guinier_point_last":169,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDFN4_datloglog_img.png","symmetry":null,"last_modified":"2021-09-27T16:14:08.122509+02:00","bragg_peak":[]}
