Overview
The Keysight G200, T150, iNano, and inSitu nano-mechanical testing systems represent the industry benchmark for quantitative mechanical property evaluation at micro- and nanoscales. Engineered on the foundation of continuous stiffness measurement (CSM)—a patented methodology first commercialized by Keysight’s predecessor in the early 1980s—these platforms implement quasi-static and dynamic indentation protocols compliant with ISO 14577 and ASTM E2546 standards. The core measurement principle relies on high-bandwidth piezoelectric actuation combined with interferometric displacement sensing and force transduction via electrostatic or electromagnetic load cells. This architecture enables sub-nanonewton force resolution and sub-angstrom depth resolution under controlled environmental conditions. Unlike conventional nanoindenters limited to ex-situ analysis, the inSitu series integrates seamlessly with scanning electron microscopes (SEM), transmission electron microscopes (TEM), and optical microscopes, permitting real-time observation of deformation mechanisms—including dislocation nucleation, phase transformation, and interfacial delamination—during mechanical loading.
Key Features
- Continuous Stiffness Measurement (CSM) with automated frequency modulation (1–200 Hz) for depth-resolved modulus and hardness mapping without unloading artifacts
- Modular platform architecture supporting interchangeable probes: Berkovich, cube-corner, spherical, and custom geometries (tip radii from 20 nm to 5 µm)
- Sub-10 nN force noise floor and <0.05 nm displacement resolution over 2 µm range, validated per NIST-traceable calibration protocols
- In-situ compatibility: SEM/TEM-compatible stages with low-vibration design, vacuum-rated (<1×10⁻⁵ mbar), and EMI-shielded electronics
- High-speed testing capability: up to 1000 indents/min with closed-loop position control and thermal drift compensation (<0.02 nm/s)
- Integrated scanning probe imaging: simultaneous topographic acquisition during indentation using integrated AFM-like feedback loops
Sample Compatibility & Compliance
The G200/T150/iNano/inSitu systems accommodate a broad spectrum of solid-state materials—including thin films (≥20 nm), bulk metals, ceramics, polymers, biomaterials, and 2D layered structures—without requiring conductive coating or vacuum-compatible preparation for non-in-situ configurations. All models comply with ISO/IEC 17025 requirements for calibration laboratories and support GLP/GMP-aligned audit trails. Software-generated reports include full metadata capture (environmental parameters, calibration certificates, operator ID, timestamped raw data), satisfying FDA 21 CFR Part 11 electronic record and signature requirements. The CSM algorithm is explicitly referenced in GB/T 22458–2008 (Chinese National Standard for nanoindentation testing), underscoring its regulatory acceptance in quality-critical sectors such as semiconductor packaging and medical device coatings.
Software & Data Management
TriboScan™ software provides unified control across all hardware variants, featuring scriptable test sequences (Python API), real-time statistical process control (SPC) dashboards, and automated pass/fail decision logic based on user-defined specification limits. Raw force-displacement datasets are stored in HDF5 format with embedded provenance tracking, enabling reproducible re-analysis and cross-platform interoperability. Data export supports ASTM E1318-compliant XML schemas and direct integration with LIMS environments via ODBC and RESTful web services. Audit logs record every parameter change, file modification, and user login event with SHA-256 hashing—fully traceable for internal QA reviews or external regulatory inspections.
Applications
- Thin-film adhesion quantification via scratch testing with acoustic emission monitoring
- Temperature-dependent creep and relaxation behavior in polymer nanocomposites (−150 °C to +300 °C with optional thermal stage)
- Mechanical mapping of grain boundaries and phase distributions in multiphase alloys
- Nanomechanical fingerprinting of battery electrode materials before/after cycling
- Time-resolved fracture toughness assessment of MEMS structural layers under cyclic loading
- Correlative in-situ TEM nanoindentation to correlate dislocation dynamics with stress-strain response
FAQ
What distinguishes CSM from traditional unloading-segment analysis?
CSM continuously modulates load at high frequency during indentation, extracting instantaneous stiffness without relying on discrete unload segments—eliminating errors from pile-up/sink-in and enabling true depth profiling of elastic modulus.
Can the inSitu system operate inside a 300 kV TEM?
Yes—the inSitu TEM variant features ultra-low magnetic signature (<0.5 µT), compact form factor (<35 mm diameter), and differential pumping interfaces compatible with high-end TEM columns.
Is third-party probe calibration supported?
Keysight-certified calibration services are available for all probe types; however, only Keysight-traceable reference standards (SRM 2241, SRM 2242) ensure compliance with ISO 14577 Annex D.
How is thermal drift compensated during long-duration tests?
A dual-sensor drift correction algorithm uses real-time thermal expansion coefficients of the frame and sample holder, updated via embedded Pt100 sensors and corrected at 10 Hz sampling rate.
Does the system support automated grid-based testing across wafer-scale samples?
Yes—integrated motorized XYZ stages (±50 mm travel, 50 nm repeatability) with vision-based alignment enable fully automated patterned testing across 300 mm wafers per SEM navigation coordinates.
