Thermo Fisher Scientific’s new accessory compatible with its FTIR spectrometers will enable art conservationists to easily and accurately perform spectral analysis to verify the authenticity of paintings, sculptures, textiles and other large artwork.
The Thermo Scientific ConservatIR FTIR external reflection accessory lets users analyze objects that do not fit inside the sample compartment of Thermo Scientific bench-top Nicolet FTIR spectrometers. The external accessory directs an infrared beam to an opto-mechanical arm that articulates in a range of motion from minus 5 to 95 degrees, enabling art authenticators to measure samples in multiple orientations. As an additional benefit, users can measure samples in two modes: specular/diffuse reflection, for non-contact analysis, or attenuated total reflection (ATR), using an optional diamond ATR sampling interface.
An integrated video camera on the accessory enables users to magnify the sample image to facilitate higher confidence in the measurement location. Once data is generated using the ConservatIR accessory, users can analyze it with Thermo Scientific OMNIC software, designed to provide ease of data collection and accurate analysis in one platform.
The ConservatIR accessory is also designed to enable accurate spectral analysis of other large objects, including automotive parts, toys, fixtures and castings.
