Once a sample has been taken using the µ-CTE, the sorbent tube is placed in an automated TD unit. The
VOCs emitted from the sample are introduced to a GC–MS for separation and analysis. Chromatographic
data is generated to identify the chemicals emitted (figure 5).

µ-CTE technology in conjunction with TD–GC–MS analysis enables the testing of VOC emissions from
raw materials through to the final devices. The generation of a comprehensive chemical profile can result
in the detection of a wide range of volatile and semi-volatile organic compounds emitted by a sample.
This methodology can be used to obtain useful emissions data on medical devices to comply with
regulations and to develop new low-VOC-emitting materials, thus protecting the patient and future-
proofing the product.
