Micro-Chamber/Thermal Extractor

Micro-Chamber/Thermal Extractor- high temperature

M-CTE250TI

The Micro-Chamber/Thermal Extractor™ (µ-CTE™) is a versatile and compact unit with up to six small cylindrical chambers that enables the sampling of chemicals released from products or materials. Released volatile and semi-volatile organic compounds (VOCs and SVOCs) are collected onto sorbent tubes for analysis by TD–GC–MS.

  • Designed for anyone needing to sample VOCs or SVOCs emitted from products and materials
  • Applications range from emissions screening of construction materials, consumer products and car trim, to aroma or fragrance profiling
  • Humidifier and permeation accessories extend capabilities of the instrument

Overview

Permeation Accessory

The Micro-Chamber/Thermal Extractor permeation accessory is a removable inert-coated stainless-steel device that enables measurement of volatiles permeating through a thin layer of material at ambient or elevated temperatures, with the use of multiple sorbent tubes allowing the breakthrough to be plotted over time.

  • Replicates real-world conditions, to provide data on migration of chemicals through materials
  • Easy to load into and remove from the μ-CTE
  • Multiple permeation accessories can be used simultaneously
  • Available for high- and low-temperature µ-CTE models in inert-coated stainless steel

Permeation mode is one of the three sampling modes possible with the Micro-Chamber/Thermal Extractor. To test the permeability of a material, a sample is stretched across the permeation accessory and secured. A small droplet of test compound is then injected into a well at the bottom of the accessory. The complete assembly is then placed inside one of the chambers, and clean air is passed over the surface of the stretched material. Permeation is then readily assessed by monitoring the air exiting each chamber, using sorbent tubes and analysis by TD–GC–MS.

O-Rings and septa are available as replacement parts and can be changed by the user.

Barrier materials are often used in protective clothing and product packaging to mitigate potentially harmful product emissions. Typical emissions include:

  • Vehicle seat covers – to prevent VOCs from polyurethane foam contaminating car cabin air
  • Food packaging film – to prevent oxygen or VOCs tainting foodstuffs
  • Protective gloves, masks – to protect against harmful chemicals, e.g. chemical warfare agents
  • Membranes used in vehicle fuel systems to prevent the loss of fuel vapour

Humidifier Accessory

Use of humidified air/gas with the Micro-Chamber/Thermal Extractor allows the closer simulation of conditions used in some reference tests and in real-life scenarios. It also improves the recoveries of some less volatile polar compounds. The Humidifier Accessory meets this need by supplying air/gas at up to 50% relative humidity at room temperature.

  • Supplies air or gas to the Micro-Chamber/Thermal Extractor at up to 50% relative humidity
  • Allows closer simulation of conditions used in reference tests
  • Enhances the recovery of some less-volatile polar compounds

The Humidifier Accessory includes:

  • Humidifier assembly, comprising:
    • Bottle humidifier
    • Check-valve
    • Rotameter (for control of flow rate)
  • Single regulator pneumatics accessory (U-GAS03) to control air/gas supply pressure
  • Hygrometer (for humidity measurement)
  • Humidity measurement test chamber
