Tekran - Model 2537Xi-NG -With Purge Cabinet

SHARE

Key Features: Class 1 Div 2 cabinet for use in hazardous environments. ASTM-6350 and ISO-6978 method compliant. Dual-bed gold sample trap design avoids analytical gold cartridge exposure to complex sample gas. Multiple automated QA routines validate method performance. Range of 1 ng/m3 to 2 mg/m3. Network enabled for remote operation. Cabinet integration and design by Tekran Partner: Orbital Gas Solutions.

instrument enclosure
  • Instrument touch screen interface does not require PC for operation
  • Local data storage, front panel USB port, and remote access for data retrieval
  • Additional functionality via optional s/w plugins (i.e. valve multiplexer)
  • Digital lamp and detector electronics w/ remote control and display
  • Low dead-volume valve assemblies with inert PEEK surfaces
  • Integrated sample and breakthrough trap assessment with option for single or combined heating to provide measurement and QA assessment options
  • Constant power heater control insures consistent temperature over heater life
  • Unique design isolates analytical cartridge from complex natural gas matrix; the cartridge is only exposed to carrier gas for optimal performance and robustness
  • Integrated permeation source allows assessment of trapping efficiency, matrix effects, and routine automated calibration
  • Instrument and enclosure design allows free-flowing inert purge gas exchange throughout instrument to improve overall safety rating
  • Simple access to serviceable components like cuvette and gold cartridges
  • Analyte: Total gaseous mercury in natural gas
  • Principle: Dual-bed gold pre-concentration with CVAFS detection.
  • Range: 1.0 ng/m3 to 2.0 mg/m3
  • Sampling Cycle: 2.0 – 60 min
  • Sampling: Alternating sample collection and analysis cycles
  • Data Outputs: Network (1), USB Device (1), USB Host (3), RS-485 (2), RS-232 (1), Analog Chart (2)
  • Sample Flow: 0.1 - 0.5 L/min
  • Flow Totalization: Precision mass flow controller (MFC)
  • Carrier Gas: Argon or Nitrogen
  • Consumption: ~125 L/day (full size tank lasts 2 to 3 months)
  • Carrier Setpoint: Precision mass flow controller provides dynamic control of carrier flow during each desorption cycle. MFC delivers superior flow stability and accuracy.
  • Calibration: Automatic multi-point calibration using internal permeation source. Manual injection port also provided
  • Physical: Self-contained with maximum internal and external case venting. 19” rack mountable (4U height)
