Knudsen Effusion Mass Spectrometry (KEMS): Advanced High-Temperature Vapor Pressure Analysis

Knudsen Effusion Mass Spectrometry (KEMS) is a robust method for precise vapor pressure measurements, especially suited to high-temperature applications. Utilizing a specialized Knudsen cell, KEMS delivers quantitative, kinetic, and thermodynamic data on isotopes and compounds by analyzing the gaseous emissions from the analyte. Built on the reliable AutoConcept platform, our KEMS system offers advanced performance for demanding analytical needs. 

Key Advantages of the AutoConcept Platform

 

  • Fully Optimized Ion Optics: Engineered for peak performance with full baking to minimize contamination.
  • High-Speed Scanning: Features a fully laminated magnet for fast, accurate scans across a range starting from 1 atomic mass unit (amu). 
  • Autotuning for Sensitivity and Resolution: Minimal lens design enables quick autotuning, ensuring consistent sensitivity and high resolution.
  • Modular and Stable Platform: The modular ion optics and stable platform make it simple to add custom features, such as a glove box, to meet specific needs.
  • Exceptional Resolution: Achieves up to 80,000 resolution, ideal for high-efficiency routine applications.
  • Dual Filament System: Equipped with dual filaments for the electron ionization (EI) source, complete with emission and trap control.
  • Thermal Stability: Comes with both heated and cooled ion source options.
  • Efficient Maintenance: Features a clip-in ion source for easy removal and maintenance, with optional locked removal for added convenience.
  • Enhanced Vacuum Integrity: Intermediate pumping system minimizes vacuum loss, maintaining a contamination-free analysis environment.

 

Advanced Features of the MSI KEMS System

Our KEMS system integrates innovative features for improved alignment, usability, and accuracy, including: 

  •  Large Analysis Chamber: Simplifies assembly and maintenance.
  • Precision Alignment in X, Y, and Z Axes: Ensures optimal alignment and minimal distance between the orifice and the EI chamber.
  • Laser and Camera for Precision Alignment: Delivers exact sample positioning.
  • Automated Pumping System: Provides efficient vacuum management.
  • Convenient Sample Replacement: Designed for quick and simple sample changes.
  • Accurate Temperature Control: Equipped with precise temperature measurement for consistent results.
  • Raised Platform Design: Improves access and usability.
  • Customizable Temperature Control System: Ensures steady and reliable high-temperature analysis.
  • Thorough System Testing: Each unit undergoes comprehensive testing for quality assurance.We offer a wide range of laboratory glassware and plasticware, including beakers, flasks, pipettes, and more. Find the right labware for your experiments.

Tailored to Your Specifications

 Our KEMS system can be fully customized to fit specific research and industry requirements: 

  •  Optional Glove Box Integration: Custom glove box installation for specialized applications.
  • Flexible Furnace Heating Options: Choose between laser heating or a resistance coil for optimal temperature control.

 Explore the full capabilities of KEMS and see how it can meet your analytical needs. Contact us to learn more about the customization options available.
