EMS 100 Glow
Discharge and Coater Targets Replacement Parts

EMS 100 Glow Discharge Unit
The EMS 100 is a simple, free-standing glow discharge system, typically used for hydrophobic to hydrophilic conversion of carbon coated TEM grids. The EMS 100 requires only a suitable rotary pump.
Freshly made carbon support films tend to have hydrophobic surfaces which inhibits the spreading of suspensions of particles in negative staining solutions. However, after Glow Discharge treatment with air, the carbon film is made hydrophilic and negatively charged, thus allowing easy spreading of aqueous suspensions. With subsequent magnesium acetate treatment the surface is made hydrophilic and positively charged.
In addition to Glow Discharge treatment using air, other process gases may be used to modify surface properties. For example, if alkylamine is used as a process gas, the carbon film surface will become hydrophilic and positively charged. On the other hand, using methanol as a process gas results in the surface becoming hydrophobic and negatively charged. Such treatments can facilitate the optional absorption of selected biomolecules.
Features
- Polarity of the head can be changed from positive to negative with respect to earth.
- H.T. vacuum interlock.
- Needle valve bleed control.
- Surface treatment and cleaning.
- Polycarbonate safety shield.
Glow Discharge Summary
| Atmosphere | Surface | Charge |
| Air | Hydrophilic | Negative |
| Air | Hydrophilic | Positive with subsequent Magnesium Acetate Treatment |
| Alkylamine | Hydrophobic | Positive |
| Methanol | Hydrophobic | Negative |
Surface Cleaning
In many instances, surfaces need to be completely cleared of contamination films or deposits. This applies particularly to EM components where such deposits impair the maintenance of a clean vacuum system. A Glow Discharge treatment can be used to clean such components ofundesirable residues.
D.C. Glow Discharge
In the DC+ Mode, the Glow Discharge system can draw up 1.5Kv. This allows high efficiency ion etching of the specimen surface to remove, for example, oxide or resist layers.
Glow Discharge
The Polarity of the Head can be switched from Positive to Negative with respect to Earth, for Carbon Film Surface Treatment or Surface Etching of Metallic Specimens.
