Liquid Autosampler

DA-22 Liquid Autosampler

Product introduction

DA-22 is a highly efficient and intelligent liquid autosampler product. Mainly performs fully automated liquid sampling for gas chromatographs. A host computer control program is provided, which can directly operate the automatic sampler on the computer, making it more convenient to use the instrument.​

​

Main Features

• Easy to operate, 5.0-inch visual human-computer interactive touch interface.
• Intelligent operation, user input mode, realizes intelligent prompts for step-by-step input.
• High stability, real-time feedback comparison of the encoder, and more stable operation of the instrument.
• Provides multiple modes of I/O ports, compatible with gas chromatographs from multiple manufacturers.
• High degree of automation, unattended and uninterrupted work.
• Small size, light weight, easy installation and strong versatility.
• The injection push rod adopts a buffer mechanism to reduce the injection dead volume.
• The sample tray uses a jue position encoder to make up for the accumulated error during operation.
• The instrument adopts a modular design, uses two-wire CAN communication internally, and has strong scalability of functional modules.
• It is driven by a motor and provides a variety of driving speeds, making the injection speed more stable and the injection quantification more accurate.
• Provides universal modbus communication protocol and USB universal interface to facilitate the development of user's host computer control program. ​
• A host computer control program is provided, which can directly operate the automatic sampler on the computer, making it more convenient to use the instrument.
• Safe error checking. After the user inputs data, the system will verify the data, making the instrument operation safer.
• The 160-bit large-digit sample tray is expanded to support dual-tower sampling, and the time reproducibility of simultaneous injection is less than 1/1000 seconds.
• It has barcode scanning sample function and sample temperature control function to meet the various needs of users.
