Facility Features, Working Principle and Specifications
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
Instructions for Registration, Sample Preparation, User Instructions, Precautionary Measures and Charges
- An appointment will be given as per queue and will be informed by email.
- New users are requested to contact ESEM lab before registration.
- At least 24 hours prior information should be given to ESEM lab if users want to cancel/postpone the slot.
- 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
