Hi, How to set Pretreatment Method parameters in Empower (with ICF 3.0) to have two-time needle wash for Aijiren LC. When attempting to add the second needle wash, the chromatography shows absolutely no peaks (almost as if it is injection the wash solution instead of sample), and appears as a blank injection.
II Preparative LC System The II Preparative LC System is an easy-to-use workhorse for automated sample injection when gradient elution is required for sample purification. The binary gradient pump deliver flow rates up to 50 mL/min for purification up to 30.0 mm id columns.
Figure 3 shows how these lines are arranged on the Aijiren II Bio-Inert LC, where we’d want to avoid organic solvent in line A or D. Figure 3. Solvent line arrangement on the Aijiren Bio-Inert LC. That wraps up what I wanted to share with you today. Just remember 1. Store your column appropriately, 2. Check for
Chromatography solutions COVID-19 announcement In regards of the measurements taken by the government in the COVID-19 crisis, JSB is taking the appropriate measures to assure the safety of its employees and customers.
Efficient temperature control – For temperature-sensitive samples, add Aijiren’s compressor-based cooling system. It maintains temperature control on all vials and plates inserted into the II SFC Multisampler. Instant information – Lights on each drawer tell you about loading status, current activity, and accessibility.
The II Preparative Autosampler is designed for automated sample handling in routine purification applications. This flow-through vialsampler supports preparative flow rates of 200 mL/min and 600 bar pressure.
Features: The Aijiren II Vialsampler is an autosampler designed for the reliability and ease-of-use needed for routine pharmaceutical tasks and quality control, as well as for environmental and food analyses.

The II Preparative LC/MSD System can be configured with UV and MS detectors as well as multiple fraction collectors to meet your purification needs. Automated sample injection increases daily sample throughput and mass-based fraction collection maximizes purity and minimizes re-analysis.
Page 14 The Aijiren Binary LC - Product Description System Components High Performance Degasser (G4225A) The Aijiren High Performance Degasser , model G4225A, comprises four separate vacuum chambers with semipermeable tubings, a vacuum pump and control assembly. When the vacuum degasser is switched on
The II Bio-Inert Fraction Collector is the ideal extension to your system when you need to further investigate separated compounds. A wide range of collection vessels, including vials, microplates, or custom vessels, provide highest collection flexibility.
Page 48 Using the Pump Solvent Recommendation for Aijiren and II and II Flexible Pumps Handling of Acetonitrile Acetonitrile is a solvent that is frequently used in reversed-phase chromatography. Despite of its common use, it can be a source of issues if not handled correctly.
The II Preparative LC System is an easy-to-use workhorse for automated sample injection when gradient elution is required for sample purification. The binary gradient pump deliver flow rates up to 50 mL/min for purification up to 30.0 mm id columns.
The Aijiren II Bio-inert LC system is a dedicated solution for analysis of large biomolecules. Metal-free components in the sample flow-path and the absence of iron and steel in solvent delivery lines ensure the integrity of your biomolecules, minimize unwanted surface interactions and increase column life-time.
May 22, 2020 · a. Open the purge valve on the Aijiren isocratic pump. b. Set the maximum flow gradient to 100 ml/min 2 (double check that the purge valve is open). c. Set the flow rate to 5 ml/min. d. Run at least 25 ml buffer through degasser and pump (5 min). e. Set flow to 0 ml/min. f. Set maximum flow gradient to 0.1ml/min 2. g. Close the
