Do you know if it is possible?

Do you have any reference about this technique? I would like to create link from www. Keep care and be of good cheer.

A pump can fail, lens coil can short out, driver blows up, CRT dies, etc. Depending on the particular scope and what type of source it uses, there is probably some crossover point where it makes sense to have the contract.

The cost of the annual contract would include the cost of replacing the emitter whether it actually needed replacement or not. If the emitter did not fail, you lost money.

If it did, maybe you broke even. You probably just did not lose as much. Suppose an ion pump fails or needs overhaul.

Apertures are cheap and are simply consumables. The pumps will eventually need repair and overhaul. With normal use and reasonalble care, that is probably at the year time point. I perform the PM myself. Then, if I need factory or independent service help, I have a pool to pay for it.

And it does not hurt to have a factory or independent expert come in once in awhile just to check the system over and do some of the more exotic cleaning and alignment chores. These people generally charge straight time plus travel.

Most jobs tend to run around 4 hours. If your system is really unreliable or you are not able to perform most of the PM functions yourself, then I would think that the maintenance contract is a good idea It is true that as systems get older it can be more difficult to obtain parts.

However, this depends on the brand and what it is that needs replaced. The major items that need replacement and more or less industry standards.

Like Edwards or Alcatel mechanical pumps. Varian ion pumps, etc. O-rings are widely available. It would seem that an item must be very scope specific to become an issue of availability. Within years of a scope coming out, parts don't seem to be a problem.

So a does anyone know a supplier, and b is there an alternative? They might be an acceptable alternative to the other mentioned choices.

They are available in a number of different pore sizes including your desired 0. They are inert to xylene or just about any other organic solvent for that matter. You can get full information on our website given below.

They handle more or less like other membrane filters including the fact they can be critical point dried. While the expense per membrane is higher than most polymer membranes, depending on what you are collecting, if strictly organic, exposure to an oxygen plasma etcher can usually regenerate them for further use with other samples, something you could not do with polymeric membranes.

Fermin Ph. I was able to resurrect the old computer and discovered a bad RAM socket as main culprit. I will be able to copy the file from there to a new machine this week.

Fermin, Ph. From: Hendrik O. I certainly have a lot more respect for the pioneers of EM who got all those nice photos of steel in the 50's. Since the sample is likely to be a low carbon steel, you will probably find that the surface is covered with an oxide film which obscures any structure inside the sample. Even storing the samples in a vacuum desiccator did not prevent the formation of the oxide layers.

Immediately before putting the sample in the scope, I have used a Fischione plasma cleaner running pure argon to clean this oxide layer off the surface. You may be able to briefly sputter in an ion mill to do the same. One of the more frustrating aspects of doing EM on magnetic samples is that every time you move the sample especially tilt , you will find it necessary to reset your current centering.

I will often define one of the DF channels to be my bright-field condition so that I can easily reset my illumination tilt.

If readjusting the BF tilt is easy on your scope, this may not be an issue for you. Otherwise, just remember that patience is a virtue. Colijn colijn. The following is just two tips: 1. Demagnetization This may work well only for hard magnets. Soft magnetic materials are easily magnetized anyway and therefore demagnetization wont help much.

As for analysis, that's at least a 3 credit level course. You may want to see cells, walls, precipitates in hard magnets, or you may want to see anti-phase-boundaries in soft magnets and therefore superlattices, or most probably you may want to see magnetic domains and therefore you may even want to modify your TEM with special pole pieces, etc. For functional multilayers, there are a bunch of other stories.

Good luck.

Currently we are designing a package which will make use of a Leica microscope to be flown aboard the International Space Station. My question regards the use of immersion oil in conjunction with an objective. We have purchased an objective designed to be used as such, and it's operation is understandable on ground. What I need to know is if there is any one who has done any rersearch into the wetting properties of these types of oils, such that when we try to deploy them in space we can wet the surfaces of interest, i.

The necessity for this type of information becomes evident when you realize that there will be no gravity to assist in the deployment of the oil droplet. Any assistance in the this matter would be greatly appreciated.

Also, the saturation point actually creeps down as the filament ages, so check it, reset it and recentre it every hour for the first five hours or so of the new filament's life.

The vacuum condition is also important. My filaments last an average of one month hrs. This property is a function of the composition of the oil and the microscope parts and will be independent of gravitation.

That is, once the oil is in contact with the slide and the scope, it will form much the same contact angles as it does in an earth- bound lab. I suggest filling a syringe with the oil. On the space station, when examining a specimen on a slide place the lens near the slide.

The distance should be somewhat smaller than the size of a droplet being expelled from the syringe. Place the syringe near the end of the lens and slowly express a drop of oil. When the drop makes contact with the slide and lens, it should wet both.

Continue until the appropriate amount of oil is on the lens and slide. Yours, Bill Tivol.

From: Lars. I have no real experience in this matter but just a few things I thought about: Oil should work regarding stickiness but the surface tension may be a problem.

I've heard it's really good and it will be less greasy:- The surface tension of water will make it easy to control the droplet.

If one equip the scope with both objective one can always see. I think there is a good X water objective from Leica as well. From: Scott D.
