One solute concentration of 14.00 mg/ml was measured at 10°C. 10 successive 2 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.","tags":[],"intensity_unit":"arbitrary","experimental_mw":8.5,"experimental_mw_error":null,"guinier_i0_mw":19.1,"guinier_i0_mw_error":0.1,"porod_mw":null,"porod_mw_error":null,"pddf_i0":347.7,"pddf_i0_error":null,"guinier_i0":356.72,"guinier_i0_error":null,"pddf_rg":4.54,"pddf_rg_error":0.02,"guinier_rg":4.495,"guinier_rg_error":1.516,"pddf_dmax":19.0,"pddf_dmax_error":0.5,"porod_volume":116.7,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":1,"guinier_point_last":4,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDVS6_datloglog_img.png","symmetry":null,"last_modified":"2025-06-16T15:29:56.969374+02:00","bragg_peak":[]}
