Size exclusion chromatography data, also known as gel permeation chromatography (GPC), was generated using a TOSOH EcoSEC HLC-8320 GPC system with TSKgel columns and a refractive index detector. The instrument used tetrahydrofuran as the eluent at 0.35 mL/min and 40 °C. Molecular weight and molecular weight distributions for samples were estimated versus polystyrene standards by author Liu, Yutong, with metadata last updated on 2026-07-06.
Use Cases
- Estimating polymer molecular weight distributions based on the described chromatography method.
- Calibrating GPC/SEC instruments using the mentioned polystyrene standards.
- Analyzing polymer sample purity and size based on the described elution and filtration process.
Strengths
- The description specifies the exact instrument model (TOSOH EcoSEC HLC-8320 GPC) and column series (TSKgel SuperHM-H, -M, and -N).
- Experimental conditions are detailed, including eluent (tetrahydrofuran), flow rate (0.35 mL/min), and temperature (40 °C).
- Molecular weight calibration is explicitly referenced against polystyrene standards.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
