Overview
The solid phase extraction instrument LC-CQ-24Y combines liquid-solid extraction and liquid phase chromatograph technology. Adsorbent adsorption of target compounds in liquid samples is used to separate from the matrix and interferers, and then elute or desorption is used to separate, purify and enrich the target compounds, so as to reduce matrix interference and improve detection sensitivity. The instrument is mainly used in food safety detection, agricultural product residue monitoring, environment protection, commodity inspection and tap water, chemical production laboratories and other fields.
Features
1. Adopt anti-cross-contamination, anti-atomization vacuum tank design, simple and fast operation.
2. The whole machine is made of high transparent Organic Glass.
3. The guide needle and internal tuberack are made of polytetrafluoroethylene material, which has strong corrosion resistance.
4. The extraction column is evenly distributed, which is convenient for grouping experiments. The extraction speed is uniform and the control adjustment is convenient.
5. The wall thickness of the vacuum tank is uniform, capable of withstanding high negative pressure above -0.098MPa, and is not easy to deform.
6. The extraction column tray is made of ultra-polymer material, which is resistant to corrosion and not easy to deform under high pressure.
Principle
The solid phase extraction instrument uses solid Adsorbent to selectively adsorb the target compound in the liquid sample to separate it from the sample matrix and interfering components. Then the target compound is released from the Adsorbent by eluting or heating adsorption, so as to realize the separation, purification and enrichment process of the target compound.
Applications
Food safety testing, agricultural product residue monitoring, environment protection, commodity inspection, tap water and chemical production laboratory
