(2) Measurement of Weight-Average Molecular Weight of Pigment Dispersant (B) The weight-average molecular weight was measured by gel permeation chromatography [GPC apparatus (HLC-8320GPC) manufactured by Tosoh Corporation, column (PW+G4000PW+G2500PW) manufactured by Tosoh Corporation, flow rate: 1.0 mL/min, temperature: 40° C.] using a solution of 0.2M phosphate buffer/acetonitrile=9/1 (volume ratio) as an eluent and polyethylene glycol having a predetermined monodispersed weight-average molecular weight as a standard substance. (3) Measurement of Solid Content Concentration 10.0 g of sodium sulfate, which had been made constant in a desiccator, was weighed in a 30 mL polypropylene container (φ=40 mm, height=30 mm), about 1.0 g of a sample was added thereto, and after mixing, the mixture was accurately weighed, maintained at 105° C. for 2 hours to remove a volatile component, and then left in the desiccator for 15 minutes to measure the mass.

Article Title: Rubber composition and crosslinked rubber molded product
Article Snippet: It is noted that the measurement of the molecular weight distribution is conducted by gel permeation chromatography (“HLC-8120GPC”, available from Tosoh Corporation) using a differential refractometer as a detector under the conditions of column: GMHHXL (available from Tosoh Corporation), column temperature: 40° C., and mobile phase: tetrahydrofuran, and calculated by converting based on polystyrene standard.

Article Title: Comparison of the molecular structures of lignin-derived fractions obtained via organosolv treatments with water/alcohol co-solvents
Article Snippet: The molecular structural analysis of lignin and lignin-derived fractions is required for the efficient conversion of lignin to commercially valuable chemicals, including phenolic compounds.. Here, the average molecular structure models of lignin-derived fractions prepared via organosolv treatments using water/1-butanol and water/ethanol co-solvents were estimated using elemental analysis, nuclear magnetic resonance (NMR), gel permeation chromatography, and infrared spectroscopic analyses.. The proportions of aromatic tertiary and quaternary C atoms and their bonds with adjacent elements were analyzed via 13C NMR spectroscopy using the distortionless enhancement by polarization transfer and quaternary C-only observation sequences.

Article Title: Ink-jet ink
Article Snippet: In this specification, the weight average molecular weight means a weight average molecular weight (in terms of polystyrene) measured with a gel permeation chromatography [manufactured by TOSOH Corporation, product number: HLC-8120GPC, column: TSKgel G-5000HXL and TSKgel GMHXL-L are used in series].

Article Title: Member for composite material, composite material, mobile body, and method for manufacturing film for composite material
Article Snippet: It should be noted that the “length direction” of a film refers to the direction (MD) in which the film is extruded from the mouthpiece (T-die), and the “transverse direction” (TD) refers to the direction orthogonal to the length direction in the surface of the film. (1) Molecular Weight Distribution (Mw/Mn), Mass Average Molecular Weight (Mw), and Number Average Molecular Weight (Mn) With respect to the raw material resin pellets, measurement was performed under the following conditions using gel permeation chromatography (HLC-8320GPC (manufactured by Tosoh Corporation)).
