Dielectric response

Instrument name: Novocontrol Alpha-A analyser 

Contact persons: Øystein Hestad and Dag Linhjell 

The Alpha-A analyser from Novocontrol can be used to analyse dielectric materials over a broad range of frequencies and temperatures ( 3 µHz – 40 MHz, -35 to 150 °C). The system is currently limited to low voltage (up to 3 V)1, but can be used on a wide range of objects/materials. Dielectric response can be measured either using custom built setups, with a liquid/powder sample cell, or the test cell provided with the temperature control system. The system is computer controlled, and both frequency and temperature sweeps can be automatically run.

1 Currently up to 3V. The test fixtures are adapted for 300 V but this required equipment not currently available at Elpowerlab 

The system consists of the following main parts (links provide additional information):

FTIR Imaging Microscope

Model: 670/620 FTIR Imaging Microscope
Manufacturer: AGILENT

Instrument responsible: Jorunn Hølto and Cedric Lesaint

FTIR Imaging Microscope for liquids and solid materials. The spectrometer has resolution 0.06 cm-1, a separate sample compartment for macroscopic samples and an ATR for rapid analysis of both solid and liquids. The interferometer is air bearing for high signal-to-noise ratio. The connected microscope has a FPA detector to render rapid FTIR Imaging possible, and a 4x plus 25x objective for a spatial resolution down to 1.4 µm at 3750 cm-1. A slide-on ATR can be used for characterization of the surface of non-reflective samples.
