Specifications include, but are not limited to: MALS capable of low-angle light scattering (LALS, ~10 °). MALS capable of Right-angle light scattering (RALS, 90 °). MALS capable High-angle light scattering (HALS, ~170 °). Sensitivity: Require light-scattering detector’s limit of detection to be 15ng of polymer per injection. MALS detector must be capable of measuring Radius of Gyration (Rg) below 3nm. Temperature-controlled RI reference cell that also flows solvent to minimize baseline drift in the measurement. Temperature controlled solvent pumps, in addition to column oven, to minimize temperature discrepancies and temperature gradients during measurement. Oven capable of operating at temperatures as high as 60 °C. Includes an autosampler capable of holding 96+ vials. Has automated RI cell purging and solvent degassing. Columns with broad solvent compatibility (THF, DMF, CHCl3, DCM, toluene, hexanes) with capable separation range of 100 Da to 400 kDa. Must include a guard column. Includes software, computer, monitor for operating the instrument. One (1) year warranty after date of installation. Operation manual – one (1) paper copy and one (1) searchable, electronic copy. Software manual (if separate from Operation Manual) – one (1) paper copy and one (1) searchable, electronic copy. Installation included. Onsite training must be provided.
