Fine but sometime problematic
voc detection via sorbant td tubes
Sometimes has problem in starting desorption if the caps of the tubes are not fitting well, which is hard to understand if it's fir or no. so you would start the run and check if it start desorbing or giving error.

Analyze of in cabin materials
Easy to use and easy to maintain. Large sample can be sampled easily on a TD tube and ran into the GC

Great piece of kit.
Volatiles in air
This is a compact piece of kit. Flexible to use for products and monitor volatiles release from a range of surfaces. Reduces the need to have clean rooms and lengthy analysis time.

Good equipment, can meet many test requirements.
VOC analysis of vehicle interior materials
It's easy to use, after couples of days training, you can operate it on your own. It's very robust, not much maintenance is required. But the temperature in the chamber is not uniform. The deviation of the temperature of the bottom and the upper can't meet our requirement.

Useful piece of equipment, reliable and easy to modify.
Volatiles analysis from surfaces
The microchamber is easy to use and to setup. It holds temperature very well and will maintain a stable temperature across the whole range. With the uCTE-250 microchamber we bought the pots are a good size and have enabled us to analyze a wide range of different samples. We have looked at both liquids and solid surfaces and being able to fit bottles and watchglasses of liquid into the chamber has proved very useful. It has also proven very easy to modify and we have been able to easily modify it to enable standard injections into the chamber without opening the lid which has proven very useful for semi-quantitative experiments. The instrument is very reliable and we have had no problems in the 3 years we have owned it. My only criticism of the microchamber is the seals on the lids of the pots, you have to be careful when closing the lids as it is quite easy to pinch the seal and damage it, but they can be easily replaced.

Leachables and Extracables
Slightly confusing functionality with regards to the interface, however it is a useful product for concentrating trace level volatiles and semi-volatiles.

Fast sampling of emissions from products and materials.
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. The capability of the Micro-Chamber/Thermal Extractor has been further extended by the release of the Humidifier Accessory, which supplies the Micro-Chamber/Thermal Extractor with air or gas at up to 50% relative humidity.
Features:
- The four-chamber model has a chamber volume of 114 mL and a maximum temperature of 250°C
- The six-chamber model has a chamber volume of 44 mL and a maximum temperature of 120°C
- Volatiles are collected on sorbent tubes for analysis by TD–GC–MS; also compatible with DNPH cartridges for formaldehyde monitoring
- No sample preparation needed – simply place the material in the chamber
- A constant flow of heated air or gas ensures rapid production of a representative VOC/SVOC profile
- Results can be correlated with longer-term reference methods
- Construction from inert-coated stainless steel – compatibility with reactive or thermally labile chemicals
- Accessories allow surface-only sampling or permeation testing
- An optional humidifier accessory (available for both models of microchamber) supplies air/gas at up to 50% relative humidity to allow closer simulation of conditions used in reference tests and to enhance the recovery of some less-volatile polar compounds
Benefits:
- Save time and money by minimising the need for third-party reference tests
- Convienient and fast – test multiple samples in minutes, not days, for efficient quality control
- Confidence in results – Data from the Micro-Chamber/Thermal Extractor has been shown to correlate with longer-term reference-test results
- Avoid tedious and time-consuming sample preparation – simply place your sample in the microchamber
- Complies with international standard methods ISO 12219-3 (interior air of road vehicles) and ASTM D7706 (rapid screening of VOC emissions from products)
- Peace-of-mind – you are buying a quality product from the recognised leader in thermal desorption instrumentation
Applications:
- RMicro-Chamber/Thermal Extractor analysing
