Gel Permeation Chromatography:

Article Title: Pan-tactic crystalline and recyclable polythioesters
Article Snippet: .. The GPC instrument consisted of an Agilent HPLC system equipped with one guard column and two PLgel 5 μm mixed-C gel permeation columns and coupled with a Wyatt DAWN HELEOS II multi-angle light scattering detector and a Wyatt Optilab TrEX dRI detector; the analysis was performed at 40° C. using chloroform as the eluent at a flow rate of 1.0 mL/min, using Wyatt ASTRA 7.1.2 molecular weight characterization software. .. The refractive index increments (dn/dc) of the linear and cyclic PBTL were determined to be 0.1638±0.0097 mL/g and 0.1516±0.0061 mL/g, respectively, obtained by batch experiments using Wyatt Optilab TrEX dRI detector and calculated using ASTRA software.

High Performance Liquid Chromatography:

Article Title: Stereodivergent transformation of a natural polyester to enantiopure PHAs.
Article Snippet: Natural chiral polymers, such as DNA, proteins, cellulose and poly[(R)-3hydroxybutyrate] ((R)-P3HB), are prevalent in their enantiopure forms.. Existing methods to synthesize enantiopure polymers focus on enantiospecific polymerization, in which only one specific enantiomer is obtained from the corresponding chiral monomer.. Here we introduce a catalytic stereodivergent synthetic strategy to access all enantiopure di-isotactic poly(3-hydroxyalkanoate) (PHA) diastereomers from bacterial (R)-P3HB as the single chiral source.

Article Title: A Chemocatalytic Route to Stereoregular Poly(3-hydroxyhexanoate) and Its Statistical and Tri-Block Copolymers.
Article Snippet: .. The SEC instrument consisted of an Agilent HPLC system equipped with one guard column and three PLgel 5 μm mixed-C gel permeation columns and coupled with a Wyatt DAWN HELEOS II multi (18)-angle light scattering detector and a Wyatt Optilab TrEX dRI detector; the analysis was performed at 40 °C using chloroform as the eluent at a flow rate of 1.0 mL min−1, using Wyatt ASTRA 7.1.3 molecular weight characterization software. .. Polymer solutions were prepared in chloroform and injected into the dRI detector by Harvard Apparatus pump 11 at a flow rate of 0.30 mL min−1.

Article Title: Biobased Poly(dodecylene Furanoate) with Inherent Advantages in Performance and Circularity
Article Snippet: .. The SEC instrument consisted of an Agilent HPLC system equipped with one guard column and three PLgel 5 μm mixed‐C gel permeation columns unless indicated otherwise and coupled with a Wyatt DAWN HELEOS II multi (18)‐angle light scattering detector and a Wyatt Optilab TrEX dRI detector; the analysis was performed at 40 °C using chloroform as the eluent at a flow rate of 1.0 mL min −1 , using Wyatt ASTRA 7.1.2 molecular weight characterization software. .. The refractive index increments (d n d c −1 ) of PDDF polymers were determined to be 0.0328 ± 0.0007 mL g −1 and 0.0308 ± 0.0008 mL g −1 , respectively, obtained by batch experiments using Wyatt Optilab TrEX dRI detector and calculated using ASTRA software.
