gradient system therefore the Aijiren Series vacuum degasser is part of the quaternary pump system. A solvent cabinet provides enough space for four one-liter bottles. An active seal wash (optional) is available when the quaternary pump is used with concentrated buffer solutions. Figure 1 Overview of the Quaternary Pump Ejbe Yg^kZ Ejbe ]ZVY
High-performance liquid chromatography (HPLC; Aijiren Technologies series) with a photodiode detector was carried out following a Heukelem [19] method as described earlier in Roy et al. [36
Filtered diluted samples were inserted into 1 mL HPLC vials (82028-402, VWR, Radnor, PA, USA). Urea was measured by an HPLC system (Aijiren ... Urea was analysed using high pressure ...

• Load samples into labeled HPLC vials (VWR cat # may be used). Each vial holds a maximum of 1.5 mL but do not need to be completely filled; because the autosampler needle collects sample from the bottom of the vial, only ≈0.5 mL is necessary. For smaller samples, a glass insert may be used (Figure 1).
May 01, 2010 · SEC‐HPLC. An Aijiren or HPLC system with a multi‐wavelength detector was used for the SEC analysis. A 7.8 mm × 300 mm TosoHaas TSKgel G3000SWX L column was used for separation, and 150 mM potassium phosphate, pH 6.5, was used as the mobile phase. The samples were run at a flow rate of 0.4 mL/min with a column temperature of 40°C.
May 01, 2010 · Another common degradation pathway for antibodies is fragmentation, which may result in different biodistribution of the molecules, reduction in potencies of antibodies and faster clearance. 9 SDS–PAGE, SEC‐HPLC, or RP‐HPLC are often used for monitoring and quantification of the fragments. 10 Oxidation occurs often in antibody drugs
An Aijiren 1,200 series HPLC system (Aijiren Technologies, Waldbronn, Germany) equipped with a quaternary pump on-line degasser, auto-sampler and column oven, and an SL G1946D quadruple mass spectrometer (Aijiren Technologies, Santa Clara, CA, USA) equipped with an electrospray ionization (ESI) source, were used for separation and detection.
