1、 Main features:

1. The electronic circuit has high integration, good reliability, simple operation, and ensures stable and reliable instrument quality. It can operate continuously for a long time, which not only ensures work efficiency but also saves maintenance costs. It automatically remembers operating parameters and does not require resetting when starting up.

2. Equipped with a gas cut-off protection system to prevent instrument damage caused by misoperation.

3. The gas path system adopts a high-precision valve structure, which greatly improves the stability of the instrument gas velocity, thereby obtaining well reproducible analysis results.

4. The signal output adopts analog signal output, which can be easily connected to the chromatographic data processor and chromatographic workstation, and can analyze the content of various components such as dimethyl ether, propane, propylene, isobutane, isobutene, n-butane, etc. in liquefied gas.

2、 Instrument configuration:

1. Gas chromatography: Thermal conductivity detector (TCD)

2. Hydrogen generator: Hydrogen is used as the carrier gas, and the purity of hydrogen is ≥ 99.9% (hydrogen generator)

3. N2000 Dual Channel Chromatography Workstation

4. Six way valve gas sampler

5. Chromatographic column: one ￠ 3 * 6-meter dimethyl ether analysis column for liquefied gas and one liquefied gas component analysis column for liquefied gas

6. Sampling bag 2L

7. Common tools

8. Computer (self equipped)

This configuration meets national standards:

(1) GB10410.3-89 "Gas Chromatography Analysis of Liquefied Petroleum Gas Components"

(2) SH/T0230-92 "Determination of Composition of Liquefied Petroleum Gas (Chromatographic Method)"

4、 After sales service commitment:

1. Warranty period: The instrument is guaranteed for 12 months from the date of self installation, debugging, and acceptance, with lifelong maintenance.

2. In case of instrument malfunction, timely response or guidance for maintenance can be provided, and professional technical service engineers can be dispatched to the site within 48 hours to troubleshoot.

3. If there is a software upgrade for the same series of instruments, our company will provide free upgrade services for users.

4. Installation and Debugging: After the user has prepared all installation conditions and requested installation, our company will send professional engineers to install and debug the instrument for free, and provide centralized on-site training on usage, maintenance, and upkeep for the user's personnel, until the user can operate the instrument proficiently and independently.

5. The auxiliary materials, spare parts, signal lines, power lines, etc. required for the installation and commissioning of the equipment are provided free of charge by our company.
