Product Description
Krypton, like the other noble gases, is used in lighting and photography. Krypton light has many spectral lines, and krypton plasma is useful in bright, high-powered gas lasers, each of which resonates and amplifies a single spectral line. Krypton fluoride also makes a useful laser.
Earth has retained all of the noble gases that were present at its formation except helium. Krypton's concentration in the atmosphere is about 1 ppm. It can be extracted from liquid air by fractional distillation. The amount of krypton in space is uncertain, because measurement is derived from meteoric activity and solar winds. The first measurements suggest an abundance of krypton in space.
Krypton's multiple emission lines make ionized krypton gas discharges appear whitish, which in turn makes krypton-based bulbs useful in photography as a brilliant white light source. Krypton is used in some photographic flashes for high speed photography. Krypton gas is also combined with other gases to make luminous signs that glow with a bright greenish-yellow light.

Applications:
1. Krypton is used in some photographic flashes for high speed photograph.
2. Krypton gas is also combined with other gases to make luminous signs that glow with a bright
greenish-yellow light.
3. Krypton is mixed with argon in energy efficient fluorescent lamps, reducing the power consumption,
but also reducing the light output and raising the cost.
4. Krypton (along with xenon) is also used to fill incandescent lamps to reduce filament evaporation and
allow higher operating temperatures.A brighter light results with more blue color than conventional
incandescent lamps.
5. Krypton's white discharge is often used to good effect in colored gas discharge tubes, which are simply
painted or stained to create the desired color (for example, "neon" type multi-colored advertising signs
are often entirely krypton-based).
6. Krypton-83 has application in magnetic resonance imaging (MRI) for imaging airways. In particular, it
enables the radiologist to distinguish between hydrophobic and hydrophilic surfaces containing an
airway.
