Understanding how materials respond to changing conditions such as temperature, pressure, tensile force and humidity is vital to define the applications they can be used for. Linkam Scientific has been developing and manufacturing thermal stages for over 30 years. These are used in many industries’ and universities around the world to aid in the characterisation of materials from polymers to biological tissue, from metals to composites, from APIs to excipients, from -196 °C to +1500 °C.
Adding a Linkam stage to your microscope or analysis system, whether it be a regular light microscope, FT-IR, Raman or even X-ray, can really help expand your understanding of the sample and its characteristics
Optical differential scanning calorimetry was very popular with visitors
The Optical DSC450 combines image capture with DSC to provide a solution that correlates enthalpy changes of samples with visual changes to the sample. The Optical DSC450 has a temperature range from -196°C to 450°C.
The new DSC has been specifically designed to work with optical microscopes. The new LINK Digital Imaging modules enables additional information to be obtained by correlating optical changes such as colour and morphology with temperature. The Thermal Analysis by Surface Characterisation (TASC) module from Linkam further enhances the capabilities of the new DSC450. TASC is a new image analysis algorithm which enables structural changes in samples to be tracked and quantified. It has the unique ability to measure local transition temperatures allowing different points on a sample to be analysed thereby providing information on sample homogeneity. TASC can also be used for dissolution studies.
Multiple physical characterisation stages were shown demonstrating the ease by which a regular optical microscope may be changed into a platform for a family of different measurements.
- TST350 – tensile test measurements
- CSS420 – complex shear studies on polymers
- LTS420E-PB4 – multiprobe electrical monitoring (shown below)
All are compatible with Linkam’s Imaging Station for users who maybe do not have access or need for an optical microscope. This innovative platform provides easy access for sample loading yet provides high quality optical images simultaneous to measuring specific materials properties. With liquid nitrogen and relative humidity controllers, users can make their measurements under a controlled environment to simulate real-life working conditions.
A new plunge freezer was demonstrated with our CMS196M cryo-CLEM stage
The CMS196M workshop was particularly well supported. It provided a first introduction to the next-generation of plunge freezers. Those attending were able to see how Linkam have approached this challenging experimental process and to talk to our development engineers about their needs and how Linkam systems can fit right into their cryo-correlative workflow.
mmc2017 once again proved to be the best UK-based exhibition to discover new opportunities about how to increase the information you can get from your microscope. Our two characterisation workshops were well-attended and provided delegates with examples of how versatile Linkam’s heating and cooling stages could be - enabling physical and chemical characterisation under different test environments.
However, we know that you may not have been able to visit us so please take the opportunity to look at our web site and see the range of applications supported. See our blog – always with new information like the paper of the month where we showcase new user publications. We look forward to seeing you there soon.
