The Aijiren Quaternary LC system offers: † Flow rate range up to 5 mL/min (required for ultrafast LC on standard bore columns with 3–4.6 mm id ) † Space for long HPLC columns (250–300 mm) † Maximum pressure of 600 bar for Rapid Resolution LC or ultrafast LC on columns up to 150 mm length.
Crawford Scientific are the leading independent provider of chromatography consumables, training and consultancy in the UK.
The II Vialsampler combines sample management and column handling in a single autosampler module. The Vialsampler injects from up to 132 standard 2 mL vials and has a pressure rating of 600 or 800 bar. Options and upgrades are available for sample cooling and heating from 4 to 40 °C.
• Performs both supercritical fluid chromatography and ultra high-performance liquid chromatography • Easily converts to either a standalone SFC or UHPLC or can integrate modules into pre-existing systems • Features 600 bar capability • System can also be built up using pre-existing , and Aijiren modules, saving costs.

Identify and correct common HPLC problems to restore column performance. Get help with peak problems (peak splitting, peak tailing, peak fronting, etc.), retention time, purge noise, and loss of resolution with example chromatograms.
A reversed-phase fast liquid chromatography (FLC) system (Aijiren LC, Les Ulis, France) equipped with an Apollo C18 Alltech column (5 µm, 250 mm × 4.6 mm, Grace, Epernon, France) maintained at +25°C coupled with an ultra-violet (UV) detector ( MWD DEAAZ00942) was used to measure NE concentrations.
The important segments of an HPLC system are the same, whether you use a modular system or a more sophisticated unit. Problems affecting overall system performance can arise in each component. Some common problems are discussed here. Solutions to these problems are presented in easy to use tables.
Thermo Scientific Routine Vials and Caps are ideal for use in most standard HPLC and GC applications and high-throughput analyses. These quality autosampler vials and caps provide consistent results for your standard and high-throughput pharmaceutical, environmental, and food and beverage applications.
Building on the history of the and series analytical HPLC, the II LC delivers robust HPLC results while delivering several ease-of-use features, making it the standard system for routine analysis. Mix and match new modules with existing instrumentation to maximize uptime and minimize disruption.
Installing the Detector3 Two Stack Configuration Two Stack Configuration for Aijiren LC To avoid excessive height of the stack when the autosampler thermostat is added to the system it is recommended to form two stacks. Some users prefer the lower height of this arrangement even without the autosampler thermostat.
