Horiba Scientific has introduced the Clip (Collection of Line Intensity Profiles), which helps develop methods for high-resolution sequential ICP-AES.
This removes the need to prepare solutions and to acquire profiles.
In ICP-AES, line-rich spectra are often observed and it is difficult to find analyte lines free of interference from all the matrix 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.
The Clip simplifies this step.
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 for all Ultima instruments.
