Watrex SCS 205 GPC Sample cleanup system

Sample clean-up is an essential method for many routine chromatography applications. One of the most common cases is analysis of polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and pesticides in complex mixtures.

The initial step is an isolation of hydrophobic (lipophilic) components from the rest of the sample mixture by gel-permeation
chromatography (GPC).

In such configuration, triglycerides (700-900Da) can be isolated from low molecular (200-300Da) PAHs, PCBs or pesticides using
GPC steric exclusion. SCS 205 is a dedicated system for GPC sample pretreatment. SCS 205 includes an isocratic pump double piston pump, manual injector with preparative sample loop, PAH/PCB preparative column (200mg sample loading capacity), fraction collector and start-up kit. .The entire system is controlled from a TFT touch display through intuitive screens.

After injection and GPC separation, the purified sample (PAHs, PCBs etc.) is captured by an automated fraction collection usinga3-way motorized switching valve. The timing of the collection is predetermined from the elution profile of the pollutants.
