Coupling spectrometer

Transfer line coupling

The transfer line coupling of the TGA or STA thermal analyzer via a heated coupling adapter and a heated transfer line transports the gases evolved to the Bruker INVENIO. The heated gas cell can be located in an external module or connected to the INVENIO via the right exit, or the gas cell may be situated at the internal position. An external gas cell allows the operator access to the FT-IR spectrometer’s great flexibility and makes it possible to add on accessories such as an ATR unit or a microscope.

The gas transfer line is characterized by a low volume and a short capillary length, thus minimizing dilution effects and leading to fast response times. To prevent cold spots and thus condensation of the gases evolved, the entire gas path is heated.
