The Laboratory ICP Spectrometer is a critical instrument for precise elemental analysis across research and industry. It enables multi-element detection at trace levels with high sensitivity and throughput. From environmental monitoring to pharmaceuticals, it ensures confident, regulatory-ready results.
A Laboratory ICP Spectrometer uses Inductively Coupled Plasma to atomize and excite samples for elemental analysis via optical emission (ICP-OES) or mass spectrometry (ICP-MS). The plasma’s high temperature ionizes atoms; emitted light (OES) or ion mass-to-charge signals (MS) are measured to identify and quantify elements—metals, non-metals, and trace species—with high precision and low detection limits.
| Feature | Details |

Q: What is the difference between ICP-OES and ICP-MS?
A: ICP-OES measures light emitted by excited atoms/ions for robust multi-element analysis at ppb–ppm levels, while ICP-MS measures mass-to-charge of ions and achieves ultra-trace (ppt) detection with broader dynamic range.
Q: What sample types can be analyzed?
A: Most liquid samples directly; solids typically require digestion. Specialized setups can handle gases or nanoparticles depending on the method.
Q: How are interferences managed?
A: ICP-OES uses spectral correction and optimized wavelength selection; ICP-MS employs collision/reaction cells and mathematical corrections to reduce polyatomic and matrix interferences.
Q: What are typical detection limits?
A: ICP-MS reaches parts-per-trillion for many elements; ICP-OES typically achieves low ppb and is ideal for routine multi-element work.
Q: Why choose ICP over AAS or XRF?
A: ICP offers simultaneous multi-element capability, faster throughput, and significantly lower detection limits (with ICP-MS), making it preferred for trace analysis and complex matrices.
