  • Provides the fastest scanning rates in fluid and air, with automated alignment of laser and detector, “smart engaging” for unparalleled productivity and detailed workflow
  • Integrates all the advantages of the Dimension Icon® platform with the use of Icon® scan head
  • Long tip-life and high resolution through the industry’s most accurate force control at the tip

Quantitative Analysis for Nanomechanical Applications

The configuration of the Dimension XR Nanomechanics for FastScan® and Icon® AFM systems offers a complete set of capabilities required to quantitatively and quickly define materials for their nanomechanical properties, on samples spanning from stiff ceramics and metals to soft and sticky composites and hydrogels.

Furthermore, the XR Nanomechanics bundled solution covers the entire evolution of nanoscale AFM nanomechanical measurement methods, such as the new, groundbreaking AFM nano-dynamic mechanical analysis from Bruker Nano Surfaces. This AFM is the first and only solution that ties to bulk DMA.

Revolutionary AFM-nDMA

An AFM can offer, for the first time, quantitative and complete viscoelastic analysis of polymers at the nanoscale, exploring materials at rheologically pertinent frequencies, in the linear regime. Reference frequency tracking, phase-drift correction, and proprietary dual-channel detection allow a small strain measurement in the rheologically pertinent 0.1 to 20 kHz range for nanoscale measurements of loss tangent, loss modulus, and storage modulus that link directly to bulk DMA.

Exclusive PeakForce QNM

This mode routinely enables quantitative characterization of nanomechanical characteristics—such as deformation, dissipation, adhesion, and modulus—and concurrently images sample topography at atomic-scale resolution.

The frequency-calibrated probes available from Bruker Nano Surfaces now allow defined adhesion and geometry to monitor the contact between the probe and sample with the least uncertainty during the measurements of soft and sticky materials in the range of <1 kPa to 100 GPa, while providing results with high-resolution nanoscale mapping.

FASTForce Volume

Through this mode, the operating frequency of linear ramps is extended by more than 400 Hz and this helps in bridging the frequency gap between standard Force Volume mapping and PeakForce QNM. Moreover, the overlap of operating frequencies enables nanomechanical correlative research between modes, providing greater measurement confidence while enabling analysis of property material frequency dependency.

Innovative FASTForce Volume CR

Contact resonance can measure an extensive range of moduli and serves as a robust tool for nanomechanical measurements. But, so far, its usage has been hindered by the limitations of contact mode, such as challenging analysis, slow imaging speed, and the need for dedicated hardware for acquiring full spectrum. These problems are resolved by XR Nanomechanics, offering reliable data of both viscoelastic and elastic characteristics.

Multi-Dimensional Nanoelectrical Characterization

The configuration of the Dimension XR Nanoelectrical for FastScan® and Icon® AFM systems comprises the most comprehensive range of electrical AFM methods in a single system. PeakForce KPFM™ and PeakForce TUNA™ have already established an incredible publication record of expanding materials studies, right from traditional contact-based electrical modes to correlative mechanical and electrical data.

The latest DataCube modes from Bruker Nano Surfaces now offer multidimensional nanoscale data at each pixel, concurrently capturing both mechanical and electrical properties in a single measurement.

Proprietary DataCube Modes

These modes make use of FASTForce Volume to execute a force-distance spectrum in each pixel, with a dwell time defined by users. Through high data capture rates, a range of electrical measurements is carried out during the dwell time, leading to mechanical and electrical spectra at each pixel. Through DataCube modes, complete characterization is achieved in a single experiment, which is not possible in a commercially available AFM.

Highest Resolution Scanning Electrochemical Imaging

The configuration of the Dimension XR Nanoelectrochemical (NanoEC) for FastScan® and Icon® AFM systems offers a turnkey solution for quantitative examination of electrochemical reactions in real time. The systems make use of PeakForce SECM™ and EC-AFM modes to carry out in situ topography scans in the electrochemical cell. They are particularly developed for long-term in situ electrode analyses in volatile solvents and under electrochemical control.

Exclusive PeakForce SECM

This mode, with less than 100-nm spatial resolution, redefines what is viable in the nanoscale visualization of chemical and electrical processes in liquid.

PeakForce SECM™ considerably enhances the resolving power over conventional techniques by orders of magnitude. This facilitates entirely new studies on biosensors, corrosion science, and energy storage systems, paving the way for novel measurements on individual nanopores, nanophases, and nanoparticles. PeakForce SECM™ is the only mode that offers concurrent capture of electrochemical, topographic, mechanical, and electrical maps with nanometer-scale lateral resolution.

Premounted PeakForce SECM™ probes available from Bruker Nano Surfaces provide safe and easy handling, and the improved holder provides an electrically stable design for sensitive signal processing. The performance of highly stable probes has been illustrated for more than 10 hours of EC testing and numerous reuse cleaning cycles.

Unlimited Flexibility to Expand Research

Any Dimension XR configuration selected by users for their studies enables the addition of several other a la carte capabilities to further customize the system for their actual application requirements, both now and in the future. Together with Bruker’s various proprietary AFM methods, modes, and mode improvements, the Dimension XR systems offer the exclusive capabilities that can take nanoscale research to a whole new level.
