The Scanning Probe Microscope (SPM) is an international surface analysis instrument developed in recent years, which is a high-tech product that integrates optical, mechanical, and electrical technology by using optoelectronics, laser technology, weak signal detection technology, applied optics technology, computer high-speed acquisition and control, and high-resolution graphics processing technology and other modern technological achievements. CD BioSciences offers FEI Quanta 200 SEM-based scanning probe microscopy imaging services.
Detectors
1. Chamber mounted Everhart-Thornley (ETD) which can be operated in various modes.
2. Large field low vacuum detector (LVD)
3. Gaseous secondary electron detector (GSED) for environmental SEM mode.
4. Polepiece mounted BSE detector
5. IR camera for viewing sample/column
Additional Attachments on the "Q1"
1. Oxford XMax20 EDS Detector
2. Gatan Alto Cryo-Stage
Additional Attachments on the "Q2"
1. Oxford EDS Detector (coming soon)
Modes/Test Conditions
1. High Vacuum (Hi Vac)
2. Low Vacuum (Low Vac)
3. Environmental SEM (ESEM)
4. Energy Dispersive X-ray
The Quanta can operate in either high vacuum or low vacuum mode, allowing a controllable humidity to exist in the chamber. The primary benefit of this is charge neutralisation, whereby it is possible to view insulating samples in the microscope without the need to coat them with a conductive gold film. This is useful if you have a sample which may react badly to the coating, or if a uniform coating isn't possible.
In addition to this, the Quanta can also operate in environmental (ESEM) mode. In this mode, the sample is chilled in a more humid environment than low vacuum mode, making it possible to image wet samples.
The FEI Quanta200 "Q1" is also equipped with the Gatan Alto Cryo stage (right hand side of image). This is a fully integrated cryo-transfer technique to rapidly freeze a sample, preserve its internal structure, then coat, fracture, and sublimate at temperatures less than -180℃
The areas of application of SPM are vast. Whether it is a basic discipline such as physics, chemistry, biology, or medicine, or an applied discipline such as materials or microelectronics, there is a place for it.
