UN1056 Rare Gases Kr Noble Gas Krypton Excimer Laser Gas Mixtures

 

 

Description:

 

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

 

The concentration of Krypton in the atmosphere by volume percent is 1.1 x 10-4. Krypton is principally shipped and used in gaseous form for excimer lasers, light bulbs, window insulation and R & D laboratory research.

 

Newradar Special Gases Material Safety Data Sheets (MSDS) are available for Krypton gas and should be used as guidelines in regard to first aid, methods of storage, handling and general use of Krypton.

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.
