Detailed introduction    

AS6 A gas chromatography automatic sampler is specially developed for the chromatographic analysis to produce samples. It eliminates complicated manual operations and improves work efficiency. Large size human-computer interactive interface, easier to operate. It can be used for high-stable and high-precision injection of liquid samples.

Main features:

● 7 Inch color touch screen. The computer and touch screen are synchronized in both directions, and the unified management of each working module. Complete post-processing and spectrum analysis.

● It can realize high-voltage multi-gradient mixing, which is convenient and concise gradient parameter setting and program operation.

● Real-time detection and automatic protection of key component parameters.

● High stability light source circuit and low temperature drift and low noise preamplifier.

● The new flow cell body design improves sensitivity and reduces dynamic baseline noise and drift.

● Standard 7725 i Manual injection, optional automatic injection device.

● 32Bit ARM The adoption of contour high-integration chips improves system operation efficiency.

● It adopts a series-connected dual pump head complementary high-pressure infusion pump, with a self-test system, and the pump body material is made of stainless steel or polymer material. It adopts gem plunger rod, one-way valve and imported sealing ring, with excellent sealing performance and durable.

● The UV detector adopts an advanced concave grating spectroscopy system, a dual-optical and dual-channel microflow flow cell, which can set time-varying wavelength analysis. A 7-inch color touch screen is used as a terminal display device, which can observe the test results and spectrum in real time and serve as a window for adjusting various operating parameters.

● The sampler of the instrument is made of internationally universal standard six-way valve, and the connecting conduit is made of stainless steel pipe or PEEK catheter； The separation column adopts domestic standards C18 column. The instrument is equipped with a column constant temperature box, and two 70 can be installed at the same time in the column box. mm ~ 250mm Long column tube. The conduits, sealing rings and nut joints used in the analysis system are the same as those of international general specifications and can be shared with the accessories of imported instruments.

● The signal output interface of the instrument can be combined with PC The computer workstation software realizes two-way communication control.

Performance Features:

● Simple and easy to operate, visual human-computer interactive touch interface.

● Intelligent, user input operations, and prompts step by step.

● Provides communication protocols and interfaces to facilitate the development of user-level computer control programs.

● High stability, real-time comparison of encoder feedback makes the equipment run more stable.
