IR Spectroscopy techqniue has been widely used to identify the chemical components, stufy confirmation changes in molecules and phase transition in mteraisl; and analyse strain/stress in materials and devices. However, the spatial resolution of traditional IR spectroscopy technique is limited by optical diffraction. With the latest ATR probe, the spetial resolution can be improved to several μm. However, this is still far below the requirements of today’s researches, especially in nanomaterials and life sciences.
Atomic force microscopy-based infrared spectroscopy (AFM-IR) is a newly exploited technique that overcomes the diffraction limit and achieves the nanoscale spatial resolution. In the past decade, a lot of improvements have been made to enhance the spatial resolution and detection sensitivity.
In this webinar, we will share the latest developments in AFM-IR technologies including using cantilever Q factor to enhance IR detection sensitivity in tapping mode, resonance technique to enhance photothermal IR detection sensitivity, and using IR evanescent field coupling to detect IR spectrum in water. These developments enabled us to achieve a spatial resolution of sub 10nm, sensitivity of single molecular layer, and expanded IR measurements to aqueous solution for life science researches. In addition to the technology development discussion, we will showcase extensive application examples to illustrate how the latest developments enable new researches, especially in nanomaterials, composite materials, life sciences, photonics and energy conversation.Read More
CryoStage for AFM
Material properties change substantially as a function of temperature, from crystallisation and melting processes at high temperatures, to phase transformation and mechanical stiffening at lower temperatures. Further energy production processes in many of today’s clean-energy materials show a strong efficiency dependence with environmental temperature.
JPK’s CryoStage provides a unique solution to investigating the temperature dependence of materials from -120°C to +220°C. Particularly relevant for polymers, it can also be applied to ceramics, magnetic materials, composites, energy materials, thin films, and even metals. Using the AFM’s superior resolution, watch and study crystallisation processes and the ordering of material phases, at the nanoscale. Use QI nanomechanical mapping capability or advanced Ramp Scripting to quantitative track stiffness and adhesive changes.Read More
ChemDetect Analyser Chemical Analyser
The ChemDetectTM Analyser is a compact, intelligent spectrometer that uses the power of quantum cascade lasers to analyse and identify chemicals. It combines the latest high-speed, broadly tunable QCL technology with advanced, uncooled detection capability. An embedded computer is programmed with chemical identification algorithms for unmatched specificity and speed.
The ChemDetect Analyser offers the advantages of a turnkey system for measuring chemical concentrations yet is configurable for OEM user. It provides spectra you can trust from the moment your turn it on. The laser module includes a built-in reference detector, and a separate high-speed signal detector captures the beam after sample interrogation. An integrated controller and data acquisition module powers the laser and receives the reference and signal detector data while drawing only 5 watts of power for the entire system. This chemical analyser is so portable that it can be taken to the sample site, whether terrestrial, airborne or beyond.Read More
DC205 Precision DC Voltage Source
New from Stanford Research Systems the DC205 low-noise, high-resolution DC voltage source is the right tool when a precision source is needed. Its bipolar, four-quadrant output delivers up to 100V with 1µV resolution and up to 50mA of current. In 4-wire mode (remote sense), the instrument corrects for lead resistance delivering accurate potential to your load. The DC205's output stability is a remarkable +/- 1ppm over 24 hours. With its linear power supply, there is no need to worry about high-frequency noise.Read More
Current Voltage Source
The MeasureReady™ precision current and voltage source from LakeShore combines premium performance with unprecedented simplicity for materials scientists and engineers requiring a precise source of voltage and current.
With extensive experience in low-noise instrumentation for research, Lake Shore has leveraged the latest electronic technologies to reduce in-band and out-of-band noise floors to levesl previously only possible using add-on filters. The result is a combination AC/DC current and voltage source that is well-suited to the challenges of characterising sensitivie materials and devices, where lower excitation signals are needed and minimum injection of noise into the measurement is required.
While sophisticated on the inside, the 155 is uncommonly straightforward to operate. Leading product designers observe that simple is much harder to accomplish than complex — just putting a touchscreen on a complex product doesn’t make it simpler. Lake Shore’s modern, user-focused design for the MeasureReady 155 presents an uncluttered and intuitive interface that instantly feels familiar and natural to anybody who owns a smartphone.
