arrow13Biological SEM Workshop: A Complete Picture

This course will introduce participants to methods of sample preparation and SEM parameters and operation needed for accurate analysis.

Examples of the endless possibilities in the field of Microscopy: SEM

Targeted Participants

Individuals who currently perform or will be responsible for the preparation of samples and /or operation of the SEM in a research, academic, or industrial setting.

Scope of Class

The preparation of samples will start with determination of ROI and subsequent selection of gross cut orientation and determination of which dehydration technique to use: freeze drying, HMDS, Hitachi’s ionic liquid or critical point drying (CPD). The chemical processing required before CPD will be stressed. Special attention will be paid to orientation, stability and grounding of the sample when mounting to facilitate ease of imaging. The advantages, disadvantages and instrument requirements for the various coating materials: Au, Pt, Pt/Pd will be discussed.

Selection of accelerating voltage (kV) and spot size are critical for surface detail, resolution, and charging and will be covered in detail. Parameters such as working distance for depth of field (Dfi) and resolution, plus tilt and raster rotate will be examined for proper image collection.


The EMS Microscopy Academy
Located in Hatfield, Pennsylvania, the Academy provides electron microscopy classes, workshops and training sessions for all fields of microscopy, including materials science and biological science.


Lecture, demonstration and hands-on practice, as well as round table discussion. Participants are encouraged to bring their own samples, if possible.

Michael Kostrna
Michael was the program director of the Electron Microscopy Technician program at Madison Area Technical College and has more than 35 years in EM technical education and research experience. He has been training EM students for 30 years and has developed curricula and lab exercises for TEM, SEM, OLM, lab safety, introductory and advanced biological EM, EM, maintenance, and x-Ray microanalysis. He has worked with companies such as SC Johnson Polymer, Dow Chemicals, Io Genetics, Virent Technologies, ABS Global, NanoOnocology, and Microscopy Innovations, and in the process gained insight to the various applications of EM.

Al Coritz
Al has been working in the Electron Microscopy field for 39 years, beginning at the Yale School of Medicine and ending up on the commercial side with several key EM companies. His specialty is Cryo-techniques and Thin Film Technology: i.e. Freeze Fracture/Rotary Shadowing, High Pressure Freezing, and more. He is currently with Electron Microscopy Sciences where he has been the Technical Director for over 20 years.
