Overview
This instrument is a specialized instrument developed after years of research, capable of qualitative and quantitative analysis of various sulfides, to meet the needs of trace sulfur analysis in the fertilizer industry, petrochemical industry, metallurgy, environmental protection, military industry, electronics, scientific research and other departments.
Product Details
Main performance characteristics:
1. Various forms of sulfur can be qualitatively and quantitatively detected separately (the microcalorimeter can only detect total sulfur and has low sensitivity). This instrument is equipped with two high-performance chromatography columns. H2S, CS2, COS, RSH, R-S-R, SO2, SF6, C4H4S and other sulfides can be separated.
2. High sensitivity: The instrument is equipped with a highly selective and sensitive flame photometric detector and signal amplification system, which can detect sulfides ranging from 5PPb-0.05PPm (with slightly different detection indicators for each model).
3. Good stability: The instrument can be used for a long time, with baseline drift<0.1mv/h
4. Good completeness: The instrument is equipped with a chromatographic data workstation or chromatographic data processor and an automatic signal display device, as well as standard gases such as H2S, CS2, COS, etc. The universal instrument can detect 0.03ppm of H2S, CS2, and COS, while the food CO2 specific type can detect 0.03ppm of H2S, CS2, and COS, and 0.1ppm of SO2. The trace sulfur analyzer designed for the petrochemical sector can analyze various forms of sulfides in gaseous hydrocarbons or liquefied gases, with a detection limit of 0.1-0.5ppm. The propylene specific type can detect 0.1ppm of H2S and 0.02ppm of COS.
5. The structure is simple, easy to operate, and the price is low.
6. Good after-sales service (including technical consultation, on-site training, installation and commissioning). The instrument comes with a one-year warranty, and after the warranty period, we will continue to be responsible for maintenance and provide long-term spare parts services.
Main technical indicators:
1. The universal type can detect H2S, CS2, and COS up to 0.03ppm.
2. Food specific CO2 can detect H2S, CS2, COS up to 0.03ppm, and SO2 up to 0.1ppm.
3. Petrochemical specialized can detect H2S, CS2, COS, RSH, and RSSR with a concentration of ≤ (0.1-0.5) ppm.
4. Acrylic specific detectable H2S ≤ 0.1ppm; ≤ 0.02ppm COS.
5. Column box temperature: room temperature~399 ℃, temperature control accuracy ± 0.1 ℃.
6. Baseline stability: The baseline drift of this instrument during long-term use shall not exceed 0.1mv/hour
7. The inlet pressure of the gas sources (N2, H2, O2) used in the instrument shall not be less than 0.3Mpa, and the purity shall not be less than 99.9%.
8. Power supply: 220V ± 5%, 50HZ, power consumption: approximately 2000W.
