Hollow Cathode Lamps - Glass Metal 100mm X 20mm | Variable Operating Current, High Voltage, Element Specific, Stable Intensity, Long Lifespan

With the support of our expert, our company is dedicated Exporter, Manufacturer and Supplier of Hollow Cathode Lamps in Vadodara, Gujarat, India.
We represent PHOTRON PTY LTD. (AUS) for hallow cathode lamps which specializes in research, development and manufacture of high quality light sources for use in analytical spectroscopy. The design for all lamps produced are based on actual use and experience with atomic absorption, UV-Vis spectrophotometers and other spectroscopic instruments. Photrona s range of deuterium and coded lamps allows all users of spectroscopic instruments a complete range of high quality lamps.

Hallow Cathode Lamps are metal-vapour discharge lamps for atomic absorption analysis. This lamp requires a specific lamp for each element to be measured.

The Hallow Cathode Lamp consists of a glass tube containing a cathode, an anode and a buffer gas (usually a noble gas). A large voltage across anode and cathode will cause the buffer gas to ionize, creating a plazma.

Hallow Cathode Lamp operation :

Two parameters that affect the analytical results are :

The hallow cathode lamp current, which affect the intensity of the source.
The spectral bandwidth of the instrument which affects the isolation of the spectral line.
