Which ICP-OES and ICP-MS instruments are available from Thermo Fisher Scientific? Product FAQ

Answer

Thermo Fisher Scientific has over thirty years of experience in designing and manufacturing ICP systems. We offer both ICP-OES and ICP-MS products. Our ICPOES products offer both dedicated radial and dual radial/axial views. In our ICP-MS portfolio, we offer both single and triple quadrupole mass spectrometers together with high-resolution magnetic sector mass spectrometers:
- Thermo Scientific iCAP 7000 Plus ICP-OES Series (https://www.thermofisher.com/uk/en/home/industrial/spectroscopy-elemental-isotope-analysis/trace-elemental-analysis/inductively-coupled-plasma-optical-emission-spectrometry-icp-oes.html)
- Thermo Scientific iCAP RQ ICP-MS (https://www.thermofisher.com/order/catalog/product/IQLAAGGAAQFAQKMBIT)
- Thermo Scientific iCAP TQ ICP-MS (https://www.thermofisher.com/order/catalog/product/731546)
- Thermo Scientific ELEMENT 2 High-Resolution ICP-MS Series (https://www.thermofisher.com/order/catalog/product/IQLAAEGAAMFABWMAFB)
- Thermo Scientific ELEMENT XR High-Resolution ICP-MS (https://www.thermofisher.com/order/catalog/product/IQLAAEGAAMFABWMAFB)

The iCAP RQ ICP-MS (https://www.thermofisher.com/order/catalog/product/IQLAAGGAAQFAQKMBIT) is the recommended model for pharmaceutical elemental impurities.

What is the difference between ICP-OES (ICP-optical emission spectroscopy) and ICP-MS (ICP-mass spectrometry)? Product FAQ

Answer

Both techniques have a similar excitation source for the sample, an inductively coupled plasma. In ICP-OES, the atoms and ions in the sample are excited by the energy provided by the plasma. After relaxation to the ground state, the atoms emit light of a characteristic wavelength, which is then separated in an optical system and detected by a photosensitive chip.

In ICP-MS, the sample is ionized and the ions are separated according to their mass/charge (m/z) ratio. Also here, each element gives a characteristic set of signals (the isotopic fingerprint). For both ICP-OES and ICP-MS, the signal intensity for each element is directly proportional to its concentration in the measured sample.

Which instrument type should I choose, one based on (ICP-optical emission spectroscopy) or ICP-MS (ICP-mass spectrometry)? Product FAQ

Answer

Both techniques are suitable for meeting the United States Pharmacopeial Convention (USP) Chapter <232> concentration limits, but the sample preparation procedure may dilute the analytes of interest to concentrations below the detection limits of an ICP-OES. ICP-MS provides a larger dynamic range, which may be a requirement for certain applications.

What is an inductively coupled plasma (ICP)? Product FAQ

Answer

In addition to solid, liquid, and gas, plasma is sometimes considered as a fourth state of matter. A plasma is formed when a gas contains a significant amount of ions and free electrons. Plasmas can be high energy, high temperature entities with temperatures of up to 10,000 degrees C. An example of a high energy plasma is a lightning flash.

In an ICP as used in ICP-optical emission spectroscopy (OES) and ICP-mass spectrometry (MS) instruments, argon (Ar) is used to generate the plasma inside a torch assembly made from quartz. The required energy (typically 1500 W) is provided through an RF frequency and applied via an induction coil surrounding the torch. The plasma is ignited using a short electrical discharge and maintained as long as the RF frequency is applied. The sample is introduced through the central channel of the torch and hence directly entering the plasma. All parts of the system are either water-cooled, or cooled using Ar at a higher flow rate.
