ICPE-9800 Series

Simultaneous ICP Atomic Emission Spectrometers

Highly Suitable for the Analysis of a Wide Variety of Samples

Simultaneous Analysis of Trace and High-Concentration Samples Without Concern for Contamination

The torch is oriented vertically to minimize any adhesion of sample on the torch walls, thus reducing memory effects. Dual analysis is achieved through software controlled switching between axial and radial view.

Axial View Diagram

The axial view of the ICPE-9800 series uses a unique the photometric separation unit (cooling jacket plus cone) installed perpendicular to the torch. In axial measurements, the system uses a small amount of purge gas to flow through in the cooling jacket to eliminate the upper low-temperature portion of the plasma. This prevents contamination of the photometry unit ensuring long term stability and high sensitivity.

ICPE-9820 Dual View transforms into Radial Only

Ultimate in robustness, certain sample matrixes require radial only optics for some organic solvents or hydrofluoric acid samples. The ICPE-9820 allows the axial cooling jacket to easily be removed without the use of tools, converting the dual view to vertically oriented torch with radial view only configuration. This feature allow users to easy switch between highly sensitive analyses with wide dynamic ranges in simple matrixes to achieving reliable results in the most complex of samples with low maintenance.

Simplifies Organic Solvent Measurements

No oxygen gas (auxiliary gas) is necessary for analyzing organic solvents, such as drugs dissolved in DMF or petroleum products diluted with xylene. The optimized plasma conditions and torch layout significantly reduce carbon deposits on the torch tip, thus enabling stable analysis. Also, since oxygen gas cylinders or gas flow lines are not necessary, it eliminates the need for associated installation work or other additional expenses.


Leading-Edge CCD Detector with One Million Pixels Capable of Simultaneous Recording of All Wavelengths

Light Spectrum

Data for all wavelengths are captured as an image formed on a two-dimensional plane using a large 1-inch CCD sensor, in the same way that a camera captures a photograph. The acquired data are saved for reviewing at any time. The wavelength can be changed after the measurement is finished, thus reducing the need to reanalyze samples and enabling faster method development. In addition, qualitative data can be read and matrix elements can be checked and corrected for, thus eliminating measurement errors due to interference.

One-Inch Back-Illuminated CCD Detector
Since the instrument employs a back-illuminated CCD with overflow drains, it provides a broad light receiving area, while also preventing blooming

Automatic System Shutdown After Analysis

The cooling temperature of the CCD is -15°C, which means it can be used at a higher temperature than a conventional semiconductor detector (-40°C). The waiting time at shutdown that is usually required in order to prevent condensation is not necessary.

High Sensitivity and High Resolution

With and Without Shcmidt Mirror Comparison

Schmidt-aberration Corrected
A Schmidt mirror is used for correcting astigmatism. Spectrometers without this function result in blurring along the perimeter of the detector, which decreases resolution and sensitivity.


Three Features Reduce Gas Consumption by Half

Gas Usage During Analysis and Standby Halved

Mini Torch Icon

Mini Torch
Mini-torch is designed to have only half the cross sectional area of standard torches. Applying the same high-frequency output to the smaller cross section increases the energy density per cross section. This improves the excitation efficiency, resulting in higher sensitivity.

Eco Mode Icon

Eco Mode
Reducing the high-frequency output to 0.5 kW and the plasma gas flow rate to about 5 L/min during standby saves energy and reduces costs. The analysis mode starts up smoothly as well, which enables stable analysis.

Torch Comparison

Reduced Startup Gas Consumption

Vacuum Icon

To enable measurements of wavelengths in the vacuum UV region (below 190 nm) ICPE-9800 systems employ a vacuum pump (rotary pump) to evacuate the air and remove oxygen from inside the spectrometer. This ensures a shorter startup time in comparison to purge-type systems. When the pump stops, a solenoid valve automatically closes to maintain the vacuum inside the spectrometer. Consequently, there is no need to worry about contamination from atmospheric air flowing back into the spectrometer after the pump stops.

Advantages of Vacuum Spectrometers

Sample Introduction System Achieves Stable Analysis for Long Periods of Time

Free Aspiration and Gravity Drain

Free Aspiration and Gravity Drain
The sample introduction system incorporates a high-accuracy nebulizer for introduction by free aspiration and a gravity drain. Therefore, a peristaltic pump is not necessary. Since there is no need to worry about a reduction in the efficiency or the variability of introduction caused by the deterioration of the pump tube, or trouble caused by improper draining, stable analysis can be accomplished for long periods of time. (If you wish to automatically add an internal standard element an optional peristaltic pump should be used.)
