Ultra High Purity 99.999% Colorless Krypton Gas For Light , Laser And Lamp


Ultra High Purity 99.999% Colorless Krypton Gas For Light , Laser And Lamp


Description:


Krypton is a rare atmospheric gas which is odorless, colorless, tasteless, nontoxic, monatomic and chemically inert.


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.

4. 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.
