Technical Specifications for Catalysis Research

Mass Analyzer: Optimized for Small Molecules

The Specification

  • Hyperbolic quadrupole mass filter
  • 1-300 amu configurable mass range
  • 0.5–1 amu resolution
  • Unit mass resolution across full range

Catalysis Application Impact

The 1-300 amu range covers all critical catalysis products: from H₂ (2 amu) and CO (28 amu) in electrocatalytic CO₂ reduction, to levoglucosan (162 amu) in biomass pyrolysis, to C₁₂-C₂₀ hydrocarbons in Fischer-Tropsch synthesis. 0.5 amu resolution separates critical isobaric interferences like CO (28) / N₂ (28) / C₂H₄ (28) for accurate quantification.

Electrocatalysis Example: CO₂ reduction product analysis requires distinguishing CO₂ (44), CO (28), CH₄ (16), C₂H₄ (28), and C₂H₆ (30). The 0.5 amu resolution and flat-topped peak profiles ensure accurate quantification even with mass drift during long kinetic experiments.

GC Interface: Flexible Sample Introduction

The Specification

  • Standard GC column interface (capillary/packed)
  • Heated transfer line: 350°C max
  • Split/splitless injector options
  • Compatible with Pyrolyzer, Headspace, Gas valves

Catalysis Application Impact

Direct connection to catalytic reactors via gas sampling valves enables online monitoring of gas-phase products. For biomass pyrolysis, the 350°C transfer line prevents condensation of heavy pyrolytic vapors (phenols, anhydrosugars) before they reach the ion source.

Biomass Pyrolysis Critical: Levoglucosan (162 amu) and other anhydrosugars are primary cellulose pyrolysis markers. These compounds require heated transfer lines (>280°C) to prevent condensation and signal loss. Standard 150°C systems lose 40-60% of these critical biomass markers.

Ion Source & Vacuum: Clean Spectra for Complex Mixtures

The Specification

  • Dual-filament EI source (70 eV, NIST searchable)
  • Oil-free diaphragm + turbomolecular pump
  • Base pressure: 5×10⁻⁴ Pa
  • All-metal 200°C chamber construction

Catalysis Application Impact

Oil-free vacuum eliminates hydrocarbon background that interferes with low-concentration catalytic products. 70 eV EI provides NIST-library searchable spectra for unknown product identification in complex biomass pyrolysates or photocatalytic mixtures. Dual filaments enable continuous operation during long catalytic runs.

Photocatalysis Application: Photocatalytic CO₂ reduction produces trace quantities of C₁-C₃ oxygenates (methanol, ethanol, acetone) alongside unreacted CO₂. Oil-free vacuum ensures ppt-level detection limits without hydrocarbon background interference from pump oil.
