Gas Standards Generator

A New Standard in Low Concentration Vapour Generation.

The new ES4100 Vapour Standards Generator is an instrument designed to calibrate most types of gas analysers, including gas chromatographs, FTIR, GC-MS, Ion Mobility Spectrometers and also environmental chambers.

Applications:

• Calibration for air quality monitoring
• Calibration of GCs or monitors used for streams
• Standards for checking contaminants and purity in gas streams
• Calibration of homeland security monitoring equipment
• Calibration for monitoring purity of pharmaceutical products

ES4100 uses Permeation Tubes or Diffusion Tubes to generate low concentration gas standards for VOCs, Acid Gases, Amines, Sulphur gases and Hydrocarbons (over 400 compounds).

Interchangeable Permeation or Diffusion Tubes are used to provide a constant output of the component gas. This constant output is mixed with a much larger controlled flow of clean air or nitrogen, to generate an accurate concentration of calibration gas.

Changing the dilution flow rate, the tube temperature, or the number of permeation tubes used, can vary the concentration output level.

The instrument can also be adapted to produce mixtures of a variety of compounds by installing the appropriate types of Permeation Tube or Diffusion Tube.

Benefits Of Using ES4100:

• Delivers ppm / ppb gas standard directly to the gas analyser.
• Produces multi-point calibration standards from each permeation tube.
• The user handles only small quantities of toxic gas – eliminates the necessity of keeping a large stock of gas cylinders.
• Safe
  • No high pressure cylinders required.
  • Removes risk of exposure.
• Repeatable
  • Drift-free output.
  • Can calibrate all analytical equipment to the same traceable standard.
• Easy To Use
  • Set the flow rate and the temperature — no other adjustments required
• Economical
  • No gas cylinders or rental required.
  • No false results.
  • Reduces the time required for calibration.
  • Calibration standard available 24/7.
  • One permeation tube can do hundreds of calibration checks.
  • Uses Disposable and liquid Permeation Tubes and also Diffusion Tubes.

Key Features

• The high thermal mass oven keeps the permeation tube at an accurate, constant temperature.
• The digital temperature controller is accurate to ±0.1°C and is traceable to UKAS.
• The ES4100 uses disposable permeation tubes, Liquid Refillable Permeation Tubes and also Diffusion Tubes.
• The internal mass flow meter measures the dilution flow to ±1.5% of full scale.
• The ES4100 is transportable and can run 24/7 with a dedicated power supply unit or any external 12VDC battery or power supply.
• The system is available with one oven module or two permeation oven modules for producing more complex gas mixtures.
