Heraeus Two-Element Hallow Cathode Lamps

Multi-Element Lamps

Heraeus manufactures the largest range of multielement lamps offering only those combinations which provide suffi cient intensity and an acceptable lifetime for each element with no spectral interference. Multi-element hollow cathode lamps are available with two to seven different element combinations. These are particularly useful for carrying out routine analysis on a number of different elements in the same sample, such as alloys. Multi element lamps are inevitably a compromise in which energy levels will be lower than single element lamps and hence noise levels may be higher. This may limit ultimate detection levels, single element lamps being preferred wherever sensitivity is an issue.
