GPC/SEC chromatograph GPC/SEC

natural gaschemicalfor gas analysis

Compact and transportable GPC/SEC system The portable system performs gel permeation chromatography/size exclusion chromatography (GPC/SEC) measurements for rapid, simple and precise determination of macromolecular properties. A single run yields a chemical fingerprint linked to macroscopic properties such as molar mass distribution and composition heterogeneity.

Key features:

• Portable design: System packaged in two interconnected rugged transport cases (one housing the analytical module and one for system control), suitable for field use and checked-baggage transport.
• Versatile sampling: Internal carousel for up to 8 liquid samples; electric 10-multi valve and injection loop valve for samples, standards and cleaning solvents; dispenser for sampling and liquid aspiration.
• Flexible configuration: Tunable UV detector wavelengths and selectable columns to adapt laboratory GPC/SEC methodology for field deployment; compatible with samples of varying viscosity including oils.
• Software control: Analysis and data management controlled via Vistachrom software.

Applications:

• GPC/THF – analysis of aromatics in oils (petroleum applications)
• GPC/THF – analysis of S8 (natural gas condensate)
• GPC – aqueous analysis of very large polymers
• HPLC – analysis of ketones and aldehydes in air with DNPH trapping
• HPLC or UHPLC – analysis of PAHs in air or water
• HPLC – analysis of pesticides in water
