For routine laboratory purification and preparation work, a liquid chromatography can easily handle the task. In practice, it can also be configured with a UV detector to form an isocratic system or a high‑pressure binary gradient system, helping the laboratory efficiently complete preparation and extraction tasks. Whether in pharmaceuticals, chemicals, food, biochemistry, or environmental protection, this system plays an important role and meets the experimental needs of many fields.
From a structural perspective, the liquid chromatography system consists of a high‑pressure pump, a detector, an injection valve, a solvent tray, a column, and workstation software. Installation is straightforward, calibration is simple, and daily operation is easy. The whole instrument runs stably and reliably; even new operators can quickly master its use, fully meeting the routine requirements of a conventional laboratory.
Liquid Chromatography System Configuration Steps
First, open the Lab software on the computer, log in to your account to enter the main interface, and then proceed with the configuration.
Once in the operation interface, find the “System Configuration” option in the main menu and click it to enter the configuration screen.
On the system configuration screen, you will see several settable items such as “Pump”, “Instrument”, “Column”, etc. Adjust these items according to your actual experimental needs.
Blue and red arrows are provided on the interface. Use them to add the desired items to the right‑hand configuration box, or to remove unneeded items – the operation is intuitive.
Find the “Instrument” item and click it; an instrument operation panel will appear. Set the communication parameters according to the requirements in the instruction manual. Only when the parameters are set correctly will the instrument connect properly, ensuring that subsequent operations are not affected.
Parameters for other items are usually already adjusted by the instrument manufacturer’s installation engineer during setup. Unless there are special circumstances or the parameters appear abnormal, there is generally no need to modify them. If you encounter parameter issues, you can also consult the instruction manual or contact a professional for inspection and adjustment.
After all settings are completed, be sure to click “OK” to save the settings and download the data. If you encounter difficulties during the configuration that you cannot resolve, it is recommended to contact the instrument manufacturer’s after‑sales engineer promptly. They can provide more professional and accurate guidance to help you solve the problem as soon as possible.
Technical Features of the Liquid Chromatography System
The front panel adopts an intelligent rotary knob design, making operation more convenient and intelligent, reducing tedious steps during use.
It is equipped with a floating plunger support structure, which effectively extends the service life of the plunger and the seals, making the instrument more durable while delivering excellent pumping performance to ensure smooth experiments.
The lamp and flow cell are easy and quick to replace. Moreover, the deuterium and tungsten lamps can be switched intelligently, minimising experiment delays caused by lamp replacement and ensuring continuous equipment operation.
It supports three measurement modes: dual‑wavelength detection, wavelength‑time programming, and stopped‑flow scanning, effectively reducing baseline noise and drift. It offers high sensitivity, low detection limits, and a wide linear range, enabling reliable quantitative analysis whether for main components, by‑products, or impurities.
An independent mode design allows one master pump to control several high‑pressure pumps of the same model. Gradient methods can be verified through the gradient curve displayed on the screen, and the system can be extended to a 4‑channel high‑pressure gradient system to meet the needs of more experimental scenarios.
Controlled by a microprocessor, combined with a high‑speed dual‑drive and parallel pump head structure, it achieves high‑speed chamber pressure feedback and compensates for refill and solvent compression effects. This ensures high flow reproducibility even over a wide dynamic range, making experimental results more stable.
