The sample, often in liquid form, is introduced into the plasma torch.
The plasma, typically generated using argon gas, ionizes the atoms in the sample at temperatures reaching 10,000 K.
The ionized atoms emit light at characteristic wavelengths, which are detected by a
spectrometer.
The intensity of the emitted light is proportional to the concentration of the respective elements in the sample.
High Sensitivity: It can detect trace amounts of elements, which is crucial for ensuring the
quality control of nanomaterials.
Accuracy: Provides precise measurements essential for reproducibility in
nanofabrication.
Wide Elemental Coverage: Capable of detecting multiple elements simultaneously, making it suitable for complex nanomaterial analysis.
Applications of ICP Analysis in Nanotechnology
