Description
IST Hollow Cathode Lamp Neon WL-22834 Barium Element AAS Spectroscopy
This is an IST hollow cathode lamp, type WL-22834, with a Barium (Ba) element cathode and Neon fill gas. Hollow cathode lamps are the standard line-source light emitters used in atomic absorption spectrometers (AAS) to provide the sharp, element-specific emission lines needed for quantitative elemental analysis. This lamp produces the characteristic Barium emission spectrum required for Ba determination by AAS.

Applications
Hollow cathode lamps are the consumable excitation sources at the heart of atomic absorption spectrometers, including flame AAS and graphite furnace AAS (GFAAS) instruments. Each lamp is element-specific: the cathode is made from the target element (here, Barium), and the sealed tube is filled with a noble carrier gas — in this case Neon — that sustains the discharge and produces the element's characteristic emission lines when current is applied. AAS instruments from manufacturers such as Perkin-Elmer, Varian, Shimadzu, Thermo, and GBC all rely on interchangeable hollow cathode lamps of this style. Barium determination by AAS is used in environmental water testing, soil analysis, geological surveys, and materials characterization. IST lamps follow the standard multi-pin base format common across most bench-top AAS platforms, making them broadly compatible with major instrument brands.
This IST WL-22834 Barium Hollow Cathode Lamp has been inspected and appears to be in good used condition. The glass envelope is intact with no visible cracks or chips, and the multi-pin base is clean and undamaged. The label is present and legible, clearly showing the type, element, and fill gas. The lamp comes in its original foam-lined hard carrying case, which shows light surface wear consistent with normal storage use. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
