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. Simultaneous analysis is possible by switching between axial and radial views.
The axial view of the ICPE-9800 series uses the photometric unit (cooling jacket plus orifice) installed perpendicular to the torch.
In axial measurements, the system causes a small amount of purge gas to flow in the axial direction in order to eliminate the upper low-temperature portion of the plasma and capture the hot portion. This prevents contamination of the photometry unit.
Analysis of High-Concentration Range and Organic Solvent Samples
Cooling Jacket Removal, Specifically for Radial View ICPE-9820
When only the radial view is used to analyze high-concentration samples or inject certain organic solvents (such as xylene), the cooling jacket can be removed to use the unit exclusively for the radial view. Removing the cooling jacket is easy.
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
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
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 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.
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.
Reduced Startup Gas Consumption
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.
Sample Introduction System Achieves Stable Analysis for Long Periods of Time
Natural 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.)
