Think of neon and I think of neon lights, those wonderful, magical glowing tubes that spell out the world's advertising messages, OPEN signs, and colored messages of all sorts. Look at my comparison of noble gas lights and you'll see why: It produces by far the brightest light. (Actually mercury and sodium vapors produce more light, but of less desirable color.)

As a noble gas neon is inert, unwilling to react with anything. Theoretically it could be used as a shield gas the same way argon is, but it isn't commonly used this way: Argon is cheaper.

Neon Antique reagent flask
3D3DAntique reagent flask.
I got a set of five different noble gas flasks on eBay for $13.50, which seemed like a good deal even though the seller described them as "probably empty". I very much doubt, however, that they are empty: At the bottom where the flask meets the tube, there is a tiny inner breakaway seal that is completely intact on all five of them. There's no visible way for the gas to have escaped. I've learned that one normally uses a steel ball, held up with a magnet, to break the seal: When you've hooked up and flushed out all the connecting tubes, you pull away the magnet and the ball drops onto the seal, breaking it and releasing the gas.
After many unworkable suggestions for proving whether the gases were still in there, several people came up with the idea of using a high voltage transformer, such as one finds in those now inexpensive plasma ball novelty lights, to try to set up an arc inside the flask, and identify the gas from the color of the discharge. Whether this is possible is sensitive to the pressure of the gas, which is not known.
Fortunately, it worked beautifully on three out of the five, and proved beyond a reasonable doubt that those three at least contain the gas claimed. The others almost certainly failed because the type and pressure of gas in them does not support an arc, not because they are empty. In fact, if they were empty, I would have gotten an arc, because the arc works through up to about half an inch of ordinary air.
You can see pictures of all the arcs along with a picture of the display stand I built for them (between 10PM and midnight of the evening they arrived) a using some of the same Carlson Maple used for the noble gas tiles on the table.
By the way, isn't it a cute oxymoron: Reagent-grade non-reactive gas.

Neon Mounted arc tube
Mounted arc tube.
In some ways, gases are a pain from a sample point of view. With the exception of chlorine and bromine they all look exactly the same: Like nothing at all. My beautiful set of noble gas flasks is beautiful because of the flasks, not what's in them, which is indistinguishable from plain air or vacuum. (So much so that I got them for a bargain price because the seller thought the were empty.)

But set up an electric current through almost any gas, and things are completely different. The current ionizes the gas, and when the electrons fall back into their orbits, they emit light of very specific frequencies. These spectral lines can easily be seen with even a very cheap pocket spectroscope, and they give the glowing tubes very unusual colors. So unusual in fact that they are basically impossible to photograph. The pictures here simply don't look at all like the real colors of these tubes, which cannot be represented by the limited red, green, and blue mixtures available in computer or printed photographs.

David Franco helped arrange these tubes, which were made by a guy who specializes in noble gas tubes and Geissler tubes (click the source link). I have tubes installed in each of the five stable noble gas spots in the table, hooked up underneath to a high voltage transformer. They are really quite beautiful. On my Noble Rack page I have all the pictures collected, along with pictures of arcs I made in my other collection of noble gas flasks.

Neon Sample from the RGB Set
Sample from the RGB Set.
The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table.

To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. I have two photographs of each sample from the set: One taken by me and one from the company. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order.

The picture on the left was taken by me. Here is the company's version (there is some variation between sets, so the pictures sometimes show different variations of the samples):

Neon Sample from the Everest Set
Sample from the Everest Set.
Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid.

To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.

Neon Hollow cathode lamp
Hollow cathode lamp.
Lamps like this are available for a very wide range of elements: Click the Sample Group link below to get a list of all the elements I have lamps like this for. They are used as light sources for atomic absorption spectrometers, which detect the presence of elements by seeing whether a sample absorbs the very specific wavelengths of light associated with the electronic transitions of the given element. The lamp uses an electric arc to stimulate the element it contains to emit its characteristic wavelengths of light: The same electronic transitions are responsible for emission and absorption, so the wavelengths are the same.
In theory, each different lamp should produce a different color of light characteristic of its element. Unfortunately, the lamps all use neon as a carrier gas: You generally have to have such a carrier gas present to maintain the electric arc. Neon emits a number of very strong orange-red lines that overwhelm the color of the specific element. In a spectrometer this is no problem because you just use a prism or diffraction grating to separate the light into a spectrum, then block out the neon lines. But it does mean that they all look pretty much the same color to the naked eye.
I've listed the price of all the lamps as $20, but that's really just a rough average: I paid varying amounts at various eBay auctions for these lamps, which list for a lot more from an instrument supplier.
(Truth in photography: These lamps all look alike. I have just duplicated a photo of one of them to use for all of them, because they really do look exactly the same regardless of what element is inside. The ones listed are all ones I actually have in the collection.)

Neon Museum-grade sample
3D3DMuseum-grade sample.
In early 2004 Max Whitby and I started selling individual element samples identical or similar to the samples we use in the museum displays we build. These are top-quality samples presented in attractive forms appropriate to the particular element. They are for sale from Max's website and also on eBay where you will find an ever-changing selection of samples (click the link to see the current listings).

This is a lovely hand-made discharge tube, powered by a small high-voltage transformer. The color is characteristic of the noble gas contained in the tube, and of course the shape spells the element's atomic symbol. In our large periodic table displays we use larger versions of these tubes: The ones photographed here are about 3" tall, but the other ones look basically identical, just bigger.

I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.

Neon Photo Card Deck of the Elements
3D3DPhoto Card Deck of the Elements.
In late 2006 I published a photo periodic table and it's been selling well enough to encourage me to make new products. This one is a particularly neat one: A complete card deck of the elements with one big five-inch (12.7cm) square card for every element. If you like this site and all the pictures on it, you'll love this card deck. And of course if you're wondering what pays for all the pictures and the internet bandwidth to let you look at them, the answer is people buying my posters and cards decks. Hint hint.

Neon Nelium-neon laser pointer
3D3DNelium-neon laser pointer.
Sure, you've seen laser pointers before, what are they, maybe $3 at the corner gas station? But those are laser diode pointers, tiny solid state devices that run on a watch battery. This is something far more exotic, a relic of a time before the very existence of laser diodes. Gather 'round children and I will tell you a tale of those times.
Back in the stone age, I'm talking here about maybe 1990, lasers were big things made of glass tubes or ruby rods, fed by high voltage power supplies. There were definitively not things you held in your hand. Then one day I see this astounding device in a catalog for the bargain price of only about $300. Having no children or other responsibilities, it seemed like a reasonable thing to buy at the time, and I am now very glad that I did, because I cannot find any evidence of this product ever having existed, not even on eBay. But I have one, and it still works.
It is a hand-held helium neon gas discharge laser that runs on two 9V batteries, for about 15 minutes. What you're looking at is the laser tube in operation with the side cover taken off. Notice the bit of foam stuck between the battery and the circuit board with a round blue capacitor on it? I stuck that in there because otherwise the miniature high voltage power supply arcs over to the battery case.
You really need to watch the spin video of this sample (click the Spin link on the left) to see the tube from all directions: We shot the rotation with the device turned on, and when the laser beam points directly at the camera, it hits the CCD and creates a lovely diffraction pattern as it reflects back from the inside surfaces of the lens. (No, it didn't damage the CCD.)
One very interesting thing to note: The color of the glow you see inside the tube is different from the color of the light coming out of the laser end. The light coming out the end is the neon red emission line, while the color coming out the side of the tube is the helium lavender/pink glow. Think about it: This is a completely uniform, isotropic gas, yet it's glowing in two different colors depending on what direction you look at it from. How can this be? That is the magic of the laser: The cavity mirrors organize the light from the neon line and stimulate (the S in LASER) it to be emitted only in line with the beam. The helium emission occurs in all directions randomly.
I thought I had lost thing thin, and when it turned up in my office I was overjoyed, it is one of my favorite gadgets, quite a marvel of miniaturization even if it is a hundred times bigger and a hundred times more expensive than the current model.
