The "HLC-8420GPC" is an integrated high-speed GPC device equipped with the necessary functional equipment for accurate molecular weight distribution measurement. Each unit, including the delivery pump, degassing section, and column oven, has been completely revamped to achieve excellent stability and reproducibility. By using options such as a solvent stocker and temperature-controlled sampler table unit, it can further enhance baseline stability and accommodate measurements of samples over time. 【Features】 ■ High stability and reproducibility ■ Fast startup ■ High speed, high separation, and solvent-saving ■ Excellent operability ■ Compliance with data integrity, including FDA 21CFR Part 11 *For more details, please refer to the PDF materials or feel free to contact us.

The "HLC-8321GPC/HT" is a high-temperature GPC dedicated device designed with a basic concept prioritizing practicality, considering stability, high sensitivity, and fast startup, while also taking into account environmental and safety aspects. It demonstrates its power in analyzing high-temperature soluble samples that are difficult to measure with general-purpose GPC devices. Measurements can be conducted from 40°C in the ambient temperature range to ultra-high temperatures of 220°C. It is compatible with samples that have high dissolution temperatures, including polyethylene, polypropylene, and PPS. 【Features】 ■ Covers ultra-high temperatures (up to 220°C) ■ Stable baseline ■ Fast startup ■ Comprehensive safety mechanisms ■ Excellent operability ■ Compliant with FDA 21 CFR Part 11 *For more details, please refer to the PDF document or feel free to contact us.

In addition to general-purpose GPC columns, we also introduce specialized SEC columns such as the ultra-fast SEC columns "SuperHZ Series" and "HXL Series," along with guidance on how to differentiate between SEC columns. 【Features】 <SuperMultiporeHZ Series> ■ Pore size-distributed semi-micro SEC column ■ Excellent linearity of calibration curves ■ No inflection points, resulting in undistorted chromatograms ■ Three grades available with different molecular weight fraction ranges *For more details, please refer to the PDF materials or feel free to contact us.

This document is a technical material that explains size exclusion chromatography (SEC). We will introduce the basic principles of SEC, measurement methods, and examples of measurements of actual samples. [Contents (excerpt)] - Physical properties and molecular weight of polymers, molecular weight distribution - Measurement methods for average molecular weight and molecular weight distribution - Molecular weight measurement using SEC - Column selection methods - Elution solvents - Sample concentration and injection volume - SEC measurement of super high molecular weight - High-temperature SEC *For more details, please refer to the PDF document or feel free to contact us.

An overview of size exclusion chromatography (aqueous GPC) using aqueous solutions as the eluent is presented. We introduce the column "TSKgel PW series," which is commonly used in these measurements. 【Contents (excerpt)】 - SEC measurement of water-soluble polymers ■ Column selection ■ Eluent selection - SEC measurement of water-soluble synthetic polymers - SEC measurement of polysaccharides and oligosaccharides *For more details, please refer to the PDF document or feel free to contact us.

The "TSKgel SuperMultiporePW series" is a size exclusion chromatography that uses a porous, multimodal packing material. Three grades with different molecular weight fraction ranges are available, allowing for measurements from high molecular weight samples to low molecular weight and oligomers. The use of a highly hydrophilic packing material suppresses hydrophobic adsorption of samples. Additionally, we also offer the "TSKgel PWXL, PW series," "TSKgel PWXL-CP series," and "TSKgel SuperAW series" in our lineup. 【Features】 ■ Uses a porous, multimodal packing material ■ Excellent linearity of calibration curves enables highly reproducible molecular weight measurements ■ No inflection points in the calibration curve, preventing any irregularities in the chromatogram ■ The use of a highly hydrophilic packing material suppresses hydrophobic adsorption of samples *For more details, please refer to the PDF document or feel free to contact us.
