Facility Features, Working Principle and Specifications
Facility Description
ESEM MODEL QUANTA 200 WITH EDS SDDF DET MODEL:ELEMENT C5
MODES: LOW VACUUM, HIGH VACUUM , ESEM
The FEI Quanta 200 scanning electron microscope is a versatile microscope with a tungsten electron source and three modes of operation. High vacuum (HV) mode allows analysis of electrically conducting and non conducting samples (non conducting samples can be analysed after sputter coating) Low Vacuum & ESEM modes allow analyzing biological and insulating samples without coating.
Resolution : 3.0 nm resolution at 30 kV Magnification : 25X to 20,000X Accelerating Voltage : 200 V to 30 kV Vacuum Modes : High Vacuum, Low vacuum, ESEM Mode
Sample Preparation, User Instructions and Precautionary Measures
- Medium for Dispersion Ethanol /Methanol / Water /Iso-propyl alcohol. Any other medium should be provided by the user. Dispersion will be done by ultrasonication.
- Kindly mark the edge of the sample to be observed for Cross section.
- Base of the sample should be flat for mounting on sample holder.
- Sample preparation if any should be done at user end (cutting the sample for CS, freeze fracturing, sample fixation for biological samples, staining of samples, oven drying should be done by the user)
- For any further query, kindly contact on Email: esem@iitb.ac.in, Contact: 022 21596862
