| HCL | Hallow Cathode Lamp |
Hollow cathode lamps are special spectrum lamp for Atomic absorption spectrophotometers.
Over diameter is 38mm. Hollow cathode lamp has a tubular cathode of metal element or alloy containing the element.The cathode is put into a glass bulb and encapsulated. With glow discharge, special spectrum of each element is emitted. There are many kinds of lamps with different elements available. We Provode 50 kinds of single element lamps and 10 kinds of multiple elements lamps.
