The inductively coupled plasma optical emission spectroscopy is programmed intelligently to examine samples thoroughly, follow processes smoothly, and be notified of the operational status from time to time.

Data Analytical

ICP OES instruments prioritize great data analytics to gain accurate results while minimizing the sample running time and not wasting any effort in remembering tasks. It is also equipped in a way that decreases the troubleshooting duration.

How It Works

A sample, most of the time in liquid form, is presented to plasma, which then separates the wavelengths found in light emission and focuses it into the detector by the optical system. The ICP OES instrumentation has four components:

  • Introduction of Sample
  • Plasma Presentation
  • Wavelength Selection in the Spectrometer
  • Detection.

Plasma

These are gasses that have been moving in excited states, atoms, and ions that function in high amounts of temperature in radio frequency.

Plasma Torch

This torch has three chambers: outer, auxiliary, and injector tube. Tangential cool gas flows amid outer and auxiliary areas. Plasma contained in the gas stays away from the exterior to avoid melting. 

Now, the plasma base is ejected using auxiliary gas flow, followed by the rupturing of the plasma due to the introduction of aerosol from the injector tube.

Radio Frequency Generator

Decreases the formation of oxide and minimizes the amount of interference as the plasma is maintained and isolated. 

Optical Design

The typical emission spectrum of ICP OES instruments is echelle-based. Consists of echelle grating and prism and multiple focus mirrors are produced. This polychromator allows the detection of simultaneous elements in a sample, stabilizing analysis and reducing sample consumption. 

Synchronous Vertical Dual View

In ICP EOS analysis, this feature in every model is used so that less gas is consumed, samples and tests are run faster and ensures no downtime compromise to any aspect of the process. It also features the Dichroic Spectral Combiner technology to evaluate the plasma and specimen better. 

With other innovative technologies, its performance is top-tier with an accurate, fast, and easy-to-handle process.

Maintenance

Instruments are furnished with predictive programs that notify when these machines’ maintenance must occur. Without that feature, maintenance may become a hassle and take more time instead of running more samples and completing tasks. It includes color-coded traffic indications for urgency. 

Dealing With Complex Samples

ICP OES has maximum analytical sensitivity with the power to determine at least 70 chemical elements with a concentration rate of parts per billion to a percent level. With a vertical torch, even the toughest liquid samples can be broken down and simplified for easy data reading.

Conclusion

With the need to have machines that perform well with the assurance of high productivity and accurate results, utilizing innovative and functional automation, the ICP EOS instruments may offer just that. The programming of this apparatus centers on time efficiency, fast data gathering, accurate results, and systematic maintenance.
