ICP Spectrometers

Inductively Coupled Plasma Spectrometer (ICP AES / ICP OES)


An inductively coupled plasma spectrometer is a tool for trace detection of metals in solution, in which a liquid sample is injected into argon gas plasma contained by a strong magnetic field. The elements in the sample become excited and the electrons emit energy at a characteristic wavelength as they return to ground state. The emitted light is then measured by optical spectrometry. This method, known as inductively coupled plasma atomic emission spectrometry (ICP-AES) or inductively coupled optical emission spectrometry (ICP-OES), is a very sensitive technique for identification and quantification of elements in a sample.

ICP Spectrometers can be used for the analysis of environmental samples, contaminants in food or water, metalloproteins in biological samples, and similar studies. Most ICP-AES instruments are designed to detect a single wavelength at a time (monochromator). Since an element can emit at multiple wavelengths, it is sometimes desirable to detect more than one wavelength at a time. This can be done by sequential scanning or by using a spectrometer that is designed to capture emissions of several wavelengths simultaneously (polychromator). Detection limits typically range from parts per million (ppm) to parts per billion (ppb), although depending on the element and instrument, can sometimes achieve less than ppb detection.

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.

ICPE-9800 Series Simultaneous Inductively Coupled Plasma Emission Spectrometers from Shimadzu


With a photometric system ideal for analyzing a large variety of samples, the ICPE-9800 series spectrometers are built to ensure maximum performance. The vertically oriented plasma torch minimizes adhesion of samples on the torch walls, reducing carryover. This allows for simultaneous analysis of trace and high-concentration samples without concern for contamination by simply switching between axial and radial views.

The ICPE-9800 Series features a leading-edge CCD (charge-coupled device) detector with one million pixels. Using this large one-inch sensor, data for all wavelengths is captured as an image on a two-dimensional plane in the same way that a camera captures a photograph. The wavelength can be changed after measurement is complete and all of the data is saved for future review, helping to eliminate measurement errors and reduce the work needed for repeated measurements.

Three key features on the ICPE-9800 systems help reduce argon gas consumption to about half of normal levels, leading to considerable cost savings:
