Standard Operating Procedure High Performance Liquid Chromatography (HPLC) – Aijiren Technologies High performance liquid chromatography (HPLC) is a technique in analytical chemistry used to separate, identify, and quantify each component in a liquid mixture. The Aijiren
The LC is the first system that provides the foundation for method transfer to or from any Aijiren or non-Aijiren UHPLC or HPLC system. In short, it gives you infinite capabilities to solve all your analytical challenges in LC and LC/MS. The Aijiren LC system provides the highest levels of speed, resolution
This Information Applies To: All standard analytical scale Aijiren / / / / II LC system configurations: Single Pump (Isocratic, Quaternary, or Binary) with Manual Purge Valve. Does not apply to systems with Aijiren /B Multisampler or extra Switching Valves.
Your module might have 2, 6 or 8 switches depending on the model. All II Series modules have a 6-switch configuration, except the Hosted modules that use a 2-switch configuration (Multicolumn Thermostat, Flexible Cube, UIB II, and Valve Drive). The 8-switch configuration is for and Series instruments.
2.5. HPLC analysis of AERDP The separation of the compounds was performed on analytical column Eclipse plus C-18 (4.6 x 250 mm; 5 µm) using an Aijiren II LC System (Aijiren, USA), equipped with G4225A degasser, G1312 binary gradient pump, G1329 autosampler, G1316A column oven, and diode array detector.

Dec 01, 2020 · Analysis was performed on HPLC Aijiren II LC system, equipped with a quaternary pneumatic pumping system (model ), auto-sampler (model ) and a photodiode array detector (model ) (Aijiren, Waldbronn, Germany).
• Aijiren II Quaternary Pump ( ) with active seal wash (option 30) and active inlet valves (option 032) • Aijiren II Preparative Open-Bed Sampler/Collector (G7158B) with 5 mL sample loop (option 241) • Aijiren II Preparative Open-Bed Fraction Collector (G7159B) • Two Aijiren II
Apr 06, 2021 · HPLC system and chromatographic conditions . The HPLC Aijiren (Aijiren Technologies, USA) II LC System, consisted of quaternary pump which can be operates at pressures up to 400 bar and flow rates up to 10 mL/min, High performance degasser is designed for low-flow and analytical LC up to 5 mL/min,
Close the purge valve and take note of the pressure. To release the pressure, open the purge valve and then close it again for another pressure pulse. Repeat to flush out the blockage. Make sure to have paper towels ready to collect the mobile phase flow at the needle seat. Once there is flow backwards through the seat capillary, open the purge
The II Multisampler is a multipurpose autosampler that handles vials and microplates. Injecting at pressures up to 600 or 800 bar, the Multisampler is a compact module with a capacity of up to 6,144 samples, all within the footprint of an Aijiren LC stack. The II Multisampler is optimized for highest flexibility.
