Anton Paar combines two of their technologies in one setup Rheology and Raman spectroscopy
A
n MCR rheometer can now be combined with a Raman spectrometer to provide information on the macromolecular behaviour and structural parameters of a material. This is important for a better understanding of changes in the chemical functionality and microstructure of various materials and their influence on processing and applications. Flexible setup that can be customised Anton Paar, manufacturer of the renowned MCR rheometer series, recently added Raman technology to their portfolio in the form of the Cora Raman spectrometer series. They now combined these two methods in one setup. One special benefit of this setup is that the MCR rheometer can also be combined with Raman spectrometers
and Raman probes of other brands. Due to their expertise in both fields, Anton Paar is able to provide and support customised solutions tailored to specific applications and requirements. In addition, other optical accessories from Anton Paar can be combined with the rheometer, such as temperature devices to apply a temperature range from -20°C to 300°C, and optical devices for UV-curing, (fluorescence) microscopy, Small Angle Light Scattering (SALS), and polarised imaging.

A whole range of applications By combining a mechanical and an optical method, a wide range of specific measurements can be performed. Possible applications are the investigation of crystallisation processes, chemical reactions (e.g. the curing of an adhesive sample), morphology of polymers, temperature behaviour and stabilities of suspensions, structural parameters of biological samples (e.g. biofilms, cell cultures), and many more.
Next generation of VIS and UV/VIS spectrophotometers he ONDA spectrophotometers are equipped with the latest features.

ata integrity in the context of laboratory analytics is a must, particularly in regulated environments. However, how is data integrity exactly defined, and what are the software features required to achieve it? A new Metrohm white paper answers these questions based on examples from modern Near-Infrared Spectroscopy (NIRS) Software. Data integrity is commonly defined by a number of properties, which are summarised by the acronyms ALCOA and ALCOA+, respectively. Hence, ALCOA stands for ‘attributable’, ‘legible’, ‘contemporaneous’, ‘original’ and ‘accurate’,
while ALCOA+ extends these attributes by the properties ‘complete’, ‘consistent’, ‘enduring’ and ‘available’. The present white paper explains these properties in detail and gives examples for each of them based on Metrohm’s NIRS software Vision Air. From the present white paper, a clear picture emerges of the functionalities that state-of-the-art laboratory software should provide in order for laboratories to safeguard the integrity of their data and
comply with, e.g. the requirements of FDA 21 CFR Part 11. At the same time, the present white paper emphasises that compliant-ready software such as Vision Air can only provide a solid base to achieve data integrity and does not spare companies from establishing a solid framework of standard operating procedures.
