airmo S - Sulfur compounds by auto GC/FPD

Product catalog summary

Overview: The airmo S is an automatic isothermal gas chromatograph designed for the analysis and monitoring of sulfur compounds using a Sulfur Specific Detector. It is suitable for applications requiring low sensitivity detection of sulfur compounds.

Targeted Compounds: The standard version targets compounds such as CS2, mercaptans (e.g., Methyl-SH, Ethyl-SH), and sulfides (e.g., DMS, DMDS, DES). Additional compounds like Isopropyl-SH and Terbutyl-SH can be analyzed upon request.

Main Markets: The device is used in ambient air monitoring, wastewater treatment plants, gas odorization and deodorization, and detecting impurities in pure gases like CO2 and CH4.

Standards: Complies with US EPA-Method 16b for total mercaptans and sulfides.

Principle of Operation: The system uses a trap at +5°C with an optional loop, inert pneumatic tubes, a high-efficiency dryer for water removal, and continuous sampling. Detection is achieved using a sulfur-specific dual flame photometric detector (FPD).

Features: The system includes automatic linearization of compounds, identification based on retention time, and automatic data validation with an internal permeation tube. The VISTACHROM® software allows remote monitoring, full traceability, threshold alarms, and data export.

Options: Options include automatic data transfer, hydrogen and zero air generators, multiple stream analysis, dilution system, heated lines, N2 generator, and dual mode operation.

Technical Specifications: The system analyzes specific sulfur compounds with detection limits as low as 0.1 ppb for double sulfur compounds and 0.2 ppb for single sulfur compounds. Detection ranges vary based on amplification settings.

Performance: Relative standard deviation is less than 5% for concentration and less than 1% for retention time over 24 hours. Cycle times are 10 minutes in airmoS or chromaS mode and 30 minutes in dual mode.

Gas Supply and Operation: Requires N2 or air as carrier gas, with specific pressure and flow requirements for sample inlet and detector operation. Operates in a temperature-controlled environment with specific power supply requirements.

Dimensions and Weight: The device is available in rack sizes of 4U or 5U, with specific dimensions and a weight of 22 kg including the integrated computer.
