This pump operates at pressures up to 600 bar and flow rates up to 10 mL/min. The II Quaternary Pump combines proven reliability with highest flexibility in automated gradient formation and solvent blending, and is recommended for a wide range of research and routine applications as well as for method development. HPLC Pumps.
In the following, the HPLC method for impurity analysis of chlorhexidine digluconate given by the European Pharmacopoeia (EP) monograph5 is transferred from an Aijiren LC system ( ) to a Thermo Scientific Vanquish Core HPLC system. Chlorhexidine is a common antiseptic and disinfectant, listed on the
In the Easy Sequence Setup, a method is selected and then the vial numbers are entered. These vial numbers are passed to the data system to be validated. The validation occurs against the currently loaded method, not the method used in the template that will actually use the vials. Temporary Solution: n/a. Fix Information: Fixed in Easy

• Use the medium sized mixers (200 µL, 400 µL) as the best balance between fast separation and low mixing ripple in UV detection. • For highest sensitivity and when mixing ripples interfere with the detection (e.g., due to use of UV -absorbing solvents), use a larger mixer volume (400 µL, 800 µL).
Mar 21, 2021 · Historically, HPLC pumps had a typical maximum pressure limit of 6,000 psi (400 bar). Since most labs are trying to increase efficiency and do more work in less time, the trend is continuing for smaller particle sizes in HPLC columns, resulting in more back pressure on the HPLC pump.
Vials Inserts for 8-425 Vials Microvolume Inserts for 2 ml, 8-425 Screw Top Vials To meet your microsampling needs, Aijiren has a variety of microvolume inserts with capacities and designs that can transform our vials from full-capacity to limited volume with one simple step. The inserts featured here are compatible with 8-425 screw top vials.
Be careful, make sure you are using the correct vial type. Other vials might have different depths. Stop Time • Set to As pump. It will use the stop time defined in the pump tab. Post Time • Typically, not needed for most experiments. • BinPump – Used to set mobile phase-related parameters. o Setup Tab Flow
Aug 17, 2021 · 7. On the tray above the pump, replace Storage buffer (0.02% NaN3 in Water) with a running buffer compatible with the column and your sample. 8. Purge the Pump (whenever changing buffers). a. Open the purge valve on the Aijiren isocratic pump. b. Set the maximum flow gradient to 100 ml/min2 (double check that the purge valve is open).
