FEI Quanta 200 SEM with Edax Detecting Unit

The FEI Quanta 200 Scanning Electron Microscope (SEM) is a versatile, high-performance imaging and microanalysis platform designed to accommodate a wide range of sample types and experimental needs. With its ability to operate in high vacuum (HV), low vacuum (LV), and environmental SEM (ESEM) modes, the Quanta 200 can analyze conductive, non-conductive, and even hydrated "wet" samples without requiring additional preparation such as coating. Integrated with an Edax energy dispersive spectroscopy (EDS) unit, this instrument enables both nanometer-scale structural imaging and compositional analysis in a single workflow, making it an essential tool for multidisciplinary laboratories.

At HiTechTrader, we supply refurbished and pre-owned FEI Quanta 200 SEM systems, ensuring researchers gain access to advanced SEM/EDS technology at significantly reduced cost compared to new instrumentation. Every system is carefully serviced, tested, and validated for performance, allowing laboratories to expand analytical capacity without compromising on accuracy or reliability.

Vessel and Construction

The Quanta 200 features a robust sample chamber designed for flexible vacuum conditions with rapid pump/vent cycles for efficient operation. Its motorized XYZ sample stage offers 50 mm XY travel, 25 mm Z movement, and tilt capability from +75° to -15°, supporting detailed imaging across a wide variety of geometries and orientations. Multiple detectors, including secondary electron (SE), backscatter electron (BSE), gaseous SE (for ESEM), and a large field detector (LFD), allow researchers to capture both high-resolution surface features and compositional contrasts with ease.

Closure and Sealing

The SEM is engineered with secure vacuum integrity to support HV, LV, and ESEM operation. Environmental SEM mode incorporates a controlled gaseous environment, enabling imaging of uncoated, non-conductive, or even hydrated samples that would otherwise be incompatible with traditional high-vacuum systems. This flexible chamber environment makes the Quanta 200 particularly valuable for materials research, biological sciences, and forensic applications.

This seamless combination allows for direct correlation of structural features with compositional data. Additional accessories and sample holders may be configured to support specialized applications such as particle size analysis, stress testing, or hydrated biological imaging.

Safe Operation Guidelines

The Quanta 200 incorporates automated vacuum control, interlocks, and chamber safety features to protect operators during use. Regular checks of detector performance, filament stability, and vacuum integrity are recommended to ensure optimal imaging conditions. The intuitive software interface streamlines workflows, reducing operator error and supporting both novice and expert users in routine QC and advanced R&D applications.
