Specifications – Aijiren Quaternary Pump Specifications Aijiren Quaternary Pump ( ) and VL version ( C) Hydraulic system Dual piston in series pump with servo-controlled variable stroke drive, floating pistons. Settable flow range Set points 0.001 - 10 mL/min, in 0.001 mL/min increments.
Aug 01, 2020 · HMF was analyzed using an HPLC system (Aijiren II, Aijiren Technologies, California, USA) equipped with pump ( Quat Pump VL, Aijiren Technologies, California, USA), vial sampler ( vial sampler, Aijiren Technologies, California, USA), and a Diode Array HPLC Detector ( DAD WR, Aijiren Technologies, California, USA) by
The HPLC system consisted of a quaternary pump system (Aijiren, VL), autosampler (Aijiren, TCC) and UV/VIS with diode array detector (Aijiren, DAD VL). Chromatography was achieved on a 4.6 mm × 100 mm, 4 μm EC-C18 Poroshell 120 column at oven temperature 55 °C.
I have a Aijiren system and analytic fraction collector available, but only silica-based RP columns – my best setup so far was using a Aijiren Poroshell 120 C18 150x4.6mm 4µm.
Introduction to the Quaternary Pump Introduction to the Quaternary Pump The quaternary pump comprises a solvent cabinet, a vacuum degasser and a four-channel gradient pump. The four-channel gradient pump comprises a high-speed proportioning valve and a pump assembly. It provides gradient generation by low pressure mixing.

Mar 15, 2013 · The chromatographic system combines an Aijiren quaternary pump and an Aijiren LC (Aijiren Tecnologies, Palo Alto, CA). It was composed of a binary pump with integrated degasser, high performance autosampler with thermostat, temperature-controlled column compartment and 2 position/10 ports switching valve (Santa Clara
For binary- and quaternary pumps you can use separate bottles. 8 Click on the Load Method button and select DEF_LC.M and press OK. Alternative double-click on the method in the method window. Page 72 Using the Detector Setting up an Analysis 9 Click on the module icons (see Figure below) and open the Setup of these modules. Figure on page 73
I used Aijiren Binary LC system equipped with a degassing unit, a quaternary pump, and diode array detector ( ). The column temperature is 33 oC, wavelenght 254 nm
Nov 19, 2014 · The most common causes of a rhythmic or wavy baseline are related to the pumping system. Typically, your pump will have two pistons and seals. If one is more worn than the other, this can cause flow and pressure variations in a very rhythmic pattern, which will also be seen by the detector.
