On June 19-21, the 21st World Pharmaceutical Raw Materials China Exhibition and the 16th World Pharmaceutical Machinery, Packaging Equipment and Materials China Exhibition were successfully held at the Shanghai New International Expo Center. At this exhibition, Tongwei Company showcased analytical liquid chromatography systems, preparative liquid chromatography systems with low-pressure preparative chromatography, evaporative light scattering detectors, and various types of chromatography columns.

Although there was continuous rain during the exhibition, it still couldn't stop everyone's enthusiasm for visiting. Groups of domestic and foreign visitors came one after another. Tongwei colleagues also answered questions and answered doubts with professional knowledge and full enthusiasm, allowing everyone to intuitively feel the serious responsibility of the instrument manufacturer.

Analytical liquid chromatography system

• There are various configurations available, including binary solvents, quaternary solvents, HPLC, and UPLC.

• No button appearance design, automatic sampler, infusion pump, column temperature box, detector full module chromatography workstation with full reverse control, real-time audit and tracking of various parameter software, more in line with regulatory requirements.

• The advantages of characteristic detectors include multiple detectors such as UV Vis, DAD, ELSD, FLD, and MSD, which can be selected to meet different application scenarios.

Preparation type liquid chromatography system

• Wide range pump head flow coverage, available in different configurations of 50mL/min and 100mL/min, enables the transfer of analysis to preparation methods, and easily achieves sample purification from nanograms to grams.

• Equipped with multiple characteristic preparation detectors such as UV Vis, DAD, ELSD, MSD, we provide you with satisfactory chromatographic purification solutions.

• We provide one-stop service for the preparation of chromatographic column consumables and the reinstallation and maintenance of chromatographic columns.

Evaporative light scattering detector

• Upgraded product of domestically produced evaporative light scattering detector.

• Liquid chromatography universal detector, designed for the detection of non UV absorbing substances, with applications in pharmaceuticals, food, chemical products, and other fields.

• Can be used in conjunction with any brand of liquid chromatography system (including conventional analytical HPLC systems, preparative HPLC systems, and Flash rapid preparative chromatography, etc.).

Low pressure preparative chromatography

• A rapid column passing technique based on chromatographic theory, with controllable target compound position and 4-CV elution, effectively ensuring method repeatability.

• The combination of thin-layer chromatography and column chromatography, intelligent software, automatically establishes optimized column passing methods to achieve the highest column efficiency and separation efficiency.

  
  

chromatographic column

We provide a series of products including capillary chromatography columns, analytical liquid chromatography columns, preparative liquid chromatography columns, and chromatographic packing materials, as well as provide reassembly and maintenance services for preparative chromatography columns.

The CPHI exhibition has come to a successful conclusion. At the upcoming Munich Shanghai Biochemical Exhibition, Tongwei looks forward to your visit. Tongwei always adheres to the customer-oriented philosophy, thinking what customers think and responding to their urgent needs, and developing the most suitable chromatographic solutions for customers!
