Too Many Lines, Not Enough Time? Just CLIP Them!

In ICP-AES, line-rich spectra are often observed and it is difficult to find analyte lines free of interference from all the matrix or concomitant element lines. This is especially true with matrices such as steel, tungsten, zirconium, precious metals and other complex matrices. Usually the analyst prepares known solutions, makes profiles for each wavelength at different concentrations of the analyte and concomitant elements and finally selects a line free of interference with adequate sensitivity. This crucial step in method development is long and tedious. It must be conducted with great care because it can greatly influence the accuracy of the results.

HORIBA Scientific simplifies this step with CLIP (Collection of Line Intensity Profiles), which assists the analyst in the development of methods for high resolution sequential ICP-AES: no more solutions to prepare and no more profiles to acquire. The profile of each line is calculated according to the instrument’s configuration: focal length, slit combination, diffraction grating and order used. Only a few minutes are needed to select lines for every element. CLIP is available as an upgrade module to help every user of an ULTIMA instrument save time and enhance the

quality of their results.
