Medium Pressure Flow controller; MP-3050FC

Product catalog summary
Overview: The document introduces a new flow control system designed for online gas chromatography (GC) analysis of products formed by catalytic reactions under medium pressure (up to 1 MPa). The system ensures that peak retention times on chromatograms remain unaffected by pressure changes.
Key Features:
  • The system employs a deactivated restrictor tube and an Open Split interface, allowing retention times to be independent of pressure.
  • Existing GC equipment, including separation columns and detectors, can be used without modifications.
  • The system is easily upgradable from Tandem and Single µ-Reactors, with optional accessories available.
Specifications:
  • Reactor pressure control ranges from 0.3 to 0.98 MPa, utilizing the GC's column head pressure controller for constant pressure control.
  • Digital display for column head pressure.
  • Compatible with gases such as helium, hydrogen, and nitrogen.
  • Standard accessories include a deactivated restrictor tube and an Open Split interface.
  • Power requirements are 100/240 VAC, 50W.
User Preparation:
  • Requires a column nut for the GC injector and a ferrule with an internal diameter of 0.5 mm.
  • Note that Auto-Shot Sampler and Selective Sampler are not compatible with the Medium-Pressure Flow Controller MP-3050FC.
Application Example:
  • The system is demonstrated for the conversion of ethanol to ethylene using a catalyst (H-ZSM-5) at 250ºC with helium as the carrier gas.
  • The split ratio is 1/100, with ethanol as the sample and a Flame Ionization Detector (FID) used for detection.
  • The column used is UA1-30M-2.0F, with a GC oven temperature program of 30ºC for 4 minutes, then increasing at 20ºC/min to 230ºC.
Conclusion: The new flow control system offers significant advantages in maintaining consistent retention times across varying pressures, enhancing the reliability and accuracy of GC analysis in medium pressure catalytic reactions.
