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.

Accessories
Automatic Sample Changer
The automatic sample changer (ASC) similarly handles routine measurements in quality control as well as requirements for research and development. It works around the clock to free your time for other challenges and allows you to make optimal use of the coupling even during the weekend. Of course, each sample can be assigned a different measurement and evaluation program. Easy-to-understand input fields lead you through the programming of a series of measurements. Unplanned analyses can also be inserted into a pre-programmed series of measurements already in progress.
