airmo S

Online monitoring of Sulfur compounds by auto GC/FPD

  • Model: airmo S
  • Manufacturer: Chromatotec

Airmo S is a fully automatic isothermal gas Chromatograph for the analysis & monitoring of sulfur compounds with Sulfur Specific Detector. This solution is specific for application where low sensitivity on sulfurs must be reached. This auto GC uses a valve with 1 sample trap, and metallic capillary columns.

Targetted compounds:
    • Standard Version: CS2; Mercaptans (Methyl-SH / Ethyl-SH…); Sulfides (DMS / DMDS / DES…)
    • Upon Request: Isopropyl-SH / Terbutyl -SH
Application:
  • Ambient Air Monitoring
  • Waste Water Treatment Plant
  • Gas odorisation & deodorisation
  • Impurities in Pure Gas (CO2, CH4…)
Category:

Principle:

  • Trap temperature at +5° C and loop in option
  • All the pneumatic tubes are inert to Sulphur compounds
  • High efficiency dryer for sample water removal
  • Continuous sampling
  • Sample is injected into column oven for separation
  • Controlled oven selects optimum temperature based on application
  • Detection achieved by a sulfur specific dual flame photometric detector (FPD)
  • Calibration with internal permeation tube

Features:

  • The double flame ensures no quenching occurs
  • Automatic linearization of compounds
  • Identification of compounds is based on their retention time (Elution from the column)
  • Automatic data validation as standard with internal permeation tube (DMS)

VISTACHROM® software:

The software developed by Chromatotec® allows:

  • Remote monitoring
  • Full traceability through archiving of results and QC
  • Set up and control of threshold alarms
  • Export of data MODBUS / MGS1 / 4-20mA / 0-10V
  • Windows 10

Options:

  • Automatic data transfer through:
    • Modbus or MSG1 communication protocol
    • Analog 4-20mA or 0-10V output
  • Hydrogen Generator
  • Zero Air Generator
  • Multiple stream analysis with Multiplexer
  • Dilution system
  • Heated lines
  • N2 Generator
  • Dual mode chromaS/airmoS
Compounds analysed: Specific sulfur compounds analysis with trap (and loop in option): Me-SH, Et-SH, DMS, DES, DMDS, CS2 …
Options: n-propyl-SH, 2-butyl-SH, Isopropyl-SH, Terbutyl-SH Only with loop in option: H2S, SO2, COS
Detection limits with trap: • 0,1 ppb double Sulfur Compounds like DMDS, CS2 etc…
• 0,2 ppb single Sulfur Compounds (MM, DMS etc..)
Detection limits with loop in option: with loop = 250 µl and amplification 2
• 14 ppb for H2S/SO2/ MM/EM/DMS/DES/COS
• 8 ppb for DMDS & CS2
Detection range with trap (selectable ppm / ppb) • 0,2 to 10 ppb (amplification 2)
• 1 to 40 ppb (amplification 1)
Detection range with loop in option (selectable ppm / ppb) ppm or ppb : amplification 1&2
• 0,01 to 10 mg/m3 or 0 to 600 mg/m3
• % / ppm / ppb level depends on compounds
for ex H2S = 0,01 to 10 mg/m3 = 7 ppb to 7 ppm
Relative Standard Deviation: • RSD < 5% on concentration over 24hrs
• RSD < 1% on Retention Time over 24hrs
Supervisor: • Full result storage (data and chromatogram)
