The II LC System is a robust HPLC that offers the widest choice of modules for analytical HPLC and entry-level UHPLC, delivering the performance, reliability, and robustness you need for highest confidence in your daily results.
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
Jan 23, 2021 · High‐performance liquid chromatography. Samples of ergosterol were analysed using HPLC Aijiren Technologies machine with a Luna® 5 mm C18(2) 100A LC column (250 mm × 4·6 mm). Conditions for the analysis were optimized at UV detection rate of 282 nm with only HPLC‐grade methanol (Fisher Chemical M/4056/17) as the mobile phase.
The Aijiren Thermostat is designed for use with other modules of the Aijiren Series or with other LC systems if adequate remote control inputs and outputs are available. The thermostat is controlled from the Aijiren Series Instant Pilot or from your Aijiren control software for LC systems.
Nov 14, 2010 · If you have the manual control module with Aijiren HPLC this problem can be managed, but firmware update in the HPLC instrumnt, required for Empower compatibility, might make older models of control modules unusable - You have to check that (and possibly invest money in a new latest control module).
2.7. High performance liquid chromatography (RP-HPLC-FLD) A reversed phased (RP) HPLC procedure was used for AFS determination in samples. The method described by Zhu et al. (2013) was followed with few modifications. A HPLC system (Aijiren Technologies, Santa Clara, CA, USA) equipped with a quaternary pump and vacuum degasser
The II LC System is a robust HPLC that offers the widest choice of modules for analytical HPLC and entry-level UHPLC, delivering the performance, reliability, and robustness you need for highest confidence in your daily results.
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.
There are HPLC autosamplers that are for use with liquid samples and others that use solid phase microextraction. Sample volume range, cycle and load times, precision and accuracy, and the container types they are compatible with are all features of HPLC autosamplers that can vary between models.
In our system, the robotic arm getting struck during sampling, especially in last few lines. The issue started on its own and the attached video shows the issue.
A maximum pressure of 600 bar to utilize smaller particle size columns for higher resolution and faster separations. Quaternary low pressure mixing pump design for binary, ternary
The II Manual Preparative LC System is an easy-to-use, entry-level solution for LC purification with upgrade possibilities to do routine purification of milligram up to gram scale quanities of materials.
