DEVICE FOR FTIR ABSORPTION SPECTROSCOPY

摘要

The invention relates to a device (1) for FTIR absorption spectroscopy, having an ATR sensor (5) and at least one ultrasonic transmitter (10) for generating an ultrasonic field in the manner of a standing wave. The ATR sensor (5) and the ultrasonic transmitter (10) are connected to a mounting (4) which is provided for attachment in a wall (2) or cover of a reactor (3) and which is set up to hold the ATR sensor (5) and the ultrasonic transmitter (10) so that they freely project into the interior of the reactor (3) in the mounted state.
