Benchtop SEMs

TM3030Plus

Benchtop Scanning Electron Microscope (SEM) with EDX for elemental analysis

Low Cost and Easy-to-Use

Hitachi has just released the latest model of their benchtop SEM, called TM3030Plus, on 03 August 2014 at the Microscopy and Microanalysis 2014 meeting in Hartford, USA. This SEM features an Ultra Variable-pressure SE Detector (UVD) for low vacuum SE imaging and a high sensitivity 4-segment BSE detector for high quality compositional imaging. The UVD has been adapted from SU3500 premium VP SEM.

Low vacuum minimises moisture evaporation and subsequent shrinkage of the sample, hence reduces the need of chemical processing and Critical Point Drying (CPD) or freeze drying. Moisture evaporation from wet samples can be further reduced by purchasing an optional -50°C cooling stage.

Low vacuum also reduces surface-charging effects on electrically non-conductive samples such as insects, microorganisms, leaf, pollen, paper, wood, fabric, plastic, ceramic etc. Using low voltage in low vacuum minimises damage on beam sensitive samples. Optional cooling stage can further minimise thermal damage due to electron beam on sensitive samples.

The TM3030Plus can identify elemental information by using an optional high quality EDX system manufactured by specialist microanalysis brands Bruker or Oxford Instruments. This EDX system can detect elements from B(5) to Am(95) in both low and high vacuums. Dedicated software module for data capture, auto element ID, elemental mapping, point & line scan and automatic report generation, greatly simplify the identification of unknown materials.

Other optional and standard features include: One click “Auto Start”, Auto Focus, Auto Brightness & Contrast, colour camera navigation, XYTR motorised stage, 3D VIEW, 9 sample holder, maximum sample size 70mm diameter & 50mm height, 120,000x magnification, SE/BSE mixed signal mode and three vacuum levels.

The Hitachi TM3030Plus represents the premium benchtop SEM on the market. With 50 years of market leading SEM design and development, this 9th generation Hitachi tabletop system provides researchers with supreme image quality and superior ease of use. The TM3030Plus is an ideal choice where, high throughput is necessary, image quality is paramount, sample preparation is detrimental and a low cost of ownership is required. Designed for use by both the novice and advanced electron microscopist, the TM3030Plus is ideal for multidisciplinary environments and specialised facilities.

Schottky FE-SEMs

SU5000

Versatile and Easy-to-Use Schottky FE-SEM

Large samples, innovative operation, convincing performance

Hitachi has released a new Schottky FESEM at the M&M in Connecticut in August 2014. The SU5000 provides a whole new user experience with the new ‘EM Wizard’ concept. The EM Wizard allows the very best results quickly and easily even at high magnification, independent of the operators skill level.

The SU5000 is an easy to use high throughput FESEM.

For low vacuum work on uncoated samples the SU5000 incorporates Hitachi's special environmental SE detector (called UVD). A new PD-BSE detector allows for true compositional contrast investigation experience and also in-lens or through the lens 'Top detector'.

Cold FE-SEMs

SU8200 Series

Innovative Cold Field Emission Gun

Unmatched Resolution and Beam Stability

This novel CFE gun employs a Hitachi patented "Mild flashing" technique and a new vacuum system which greatly minimizes gas molecule deposition on the emitter tip. The emitter always operates in a "clean" state, and emission current and beam stability are significantly improved. The result is the ultimate SEM electron source offering high S/N, stability, and uncompromising resolution performance at low acceleration voltages. Further, these enhanced performance capabilities open a new gateway for low voltage elemental microanalysis.

SU8200 system features include a new top detector filtering system for enhanced electron detection specificity. Fine contrast differentiation is now achieved by selectively filtering inelastic scattering electrons and directly detecting specific energy back scattered electrons. This selective filtering is particularly powerful for enhancing material contrast at low acceleration voltages. Vibration control measures for the stage and chamber, and optimization of the optical system contribute to the high resolution system performance of 0.8 nm at 15 kV and 1.1 nm at 1 kV.
