cobalt

A metallic element (atomic number 27; atomic weight 58.93) critical to the formation of red cells, maintenance of neural tissue, and in certain metabolic reactions. Cobalt is the central ion in vitamin B12; it is present in dairy products, organ meats, shellfish and sea vegetables.

According to Cobolt, it offers the best balance between scattering efficiency, influence of fluorescence, detector efficiency and availability of high-quality laser sources.
For most fixed-grating systems, the laser line width should be a few 10pm or less to avoid limiting the spectral resolution of the system, according to Cobolt. However, high resolution systems may require line widths less than that.
