3. Chromatography workstation

It is software developed based on Windows 32-bit system, compatible with Windows XP/Windows 7/Windows 10 operating system, graphical user interface, and window operation style

Fully support GLP/FDA-21CFR Part 11 electronic signature authentication, data validity and security, system authentication tools (IQ/OQ), and system suitability testing (SST).

A universal chromatographic workstation that can obtain analysis results online and is suitable for multiple users.

It can provide timely analysis of condition parameters and analysis results, and real-time online monitoring and collection of pump pressure change data.

It has the function of tracing instrument related data and operating conditions, which facilitates troubleshooting.

It can be upgraded to be compatible with third-party instruments and can expand multiple detectors, such as evaporative light scattering detectors.

Experimental results can be output in formats such as PDF. Flexible calculation and easy modification. Gradient mode: Pre programmed with multiple gradient curves, divided into four types: 1 linear, 2 step, 4 concave, and 4 convex

It can automatically perform fast data collection and subsequent processing.

4. Automatic fraction collector

Automatic fraction collector is a new generation of microcomputer controlled instrument provided for laboratory automation. It can automatically collect liquid chromatography solutions in test tubes, and can choose the control mode of time period, volume, slope or peak height collection.

Classic XY structure, concise, intuitive and clear

Intuitive and visual control software:

Manual collection or automatic collection can be achieved through software

Multiple collection modes. Distillates can be collected based on time, peak value, slope, or volume

Can be used for assembly of different brands or complete sets of chromatography/chromatography systems, compatible with different detectors

Easy installation, safe and reliable performance, low noise, and simple maintenance

External pipeline design to minimize dead volume and reduce collection errors caused by diffusion as much as possible

Collection preview function, more convenient for method development and optimization
