Hollow Cathode Lamp - Thorium with Argon Gas Fill - 1.5" - Non-Coded

isoSPEC lamps are designed and manufactured to achieve all of the following fundamental requirements for a spectral line source. • Intense emission of resonance (ground state derived) lines. • Narrow line width, for maximum sensitivity and linearity. • Minimal spectral interference from continuum emission, present in the cathode. • Rapid warm up to produce stable long term light emission. • Noise free operation and long running life and a 5-year shelf life. • Cathode materials and geometry achieve a combination of spectral purity and a suitable sputtering rate. A high sputtering rate will give high intensity at the expense of lamp life, sensitivity and linearity. isoSPEC lamps have been tested and found to work as well as lamps sold specifically for SMITH-HIEFTJE background correction, however due to the high energy pulse used, some elements will be consumed at a higher rate reducing lamp life.
