INQUIRY

ZHIYI-1123 series gas chromatography is widely used in petrochemical, fine chemical, biological medicine,
environmental protection, food hygiene, high purity gas, electricity, wine making, scientific research and education
and other fields.

ZHIYI-1123 series network-based gas chromatography is a new digital full control gas chromatography. The instrument

has fully absorbed the advanced technology of foreign similar products and adopted the leading manufacturing
technology to ensure the reliability and trouble-free operation time of the instrument. It can not only maximize the
normal operation time, reduce the number of maintenance, and in the structure of more concise and reasonable,
simple to learn, easy to operate.

ZHIYI-1123 gas chromatography gas circuit control has two modes of manual and electronic gas circuit EPC/EFC
control, advanced electronic gas circuit control (EPC/EFC) system, can provide industry users with industry-leading
excellent quality and reliable results. The instrument has a unique network remote transmission and control
function, so that the instrument in unattended, decentralized detection, centralized control into a reality; Data
analysis results can be connected to DCS to complete the statistics, analysis and monitoring of chromatographic
component content and improve the automation of the production process.

All inlet and detector gas paths for the ZHIYI-1123 gas chromatography can be controlled by an electronic gas circuit
(EPC/EFC) to provide better retention time and peak area accuracy. Instrument users can set various parameters
such as gas flow rate, shunt ratio, external events, automatic sampler, temperature and detector through the
reverse control software, and save all parameters of the analysis method. The digital circuit keeps Settings
consistent between operators on each run. As a result, users can achieve better retention time reproducibility and
more consistent and reliable results.

ZHIYI-1123 series network-based gas chromatography can be configured with 6-bit, 15-bit, and 150-bit liquid
automatic samplers, and each parameter can be controlled by the reverse control software, which will bring better
repeatability and improve work efficiency, while eliminating errors caused by manual samplers.
