Unleashing the analytical power of ICP using Axetris MFCs

Inductively Coupled Plasma

Axetris, Mass Flow Devices

ICP-MS and ICP-OES are powerful analytical techniques where gas flow control plays a critical role in plasma generation and control. Axetris MFCs provide key advantages towards ensuring the highest analytical performance.

Inductively Coupled Plasma (ICP) combined with a Mass Spectrometer (ICP-MS) or an Optical Emission Spectroscope (ICP-OES) are extremely popular atomic spectroscopy techniques.
Applications are wide-ranging within the environmental, food, pharmaceutical and semiconductor industries. Typically, ICP is an argon plasma reaching temperatures of up to
10'000 K, thereby allowing complete atomization of the analyte into elements for a complete analysis.

 

Gas flow control plays a critical role in maximizing analytical performance of ICP techniques:

 

  • Plasma and auxiliary flows support plasma generation and control. The quality of plasma is directly related to precision of gas flow control.
  • Nebulizer gas flow should be highly reproducible to achieve high detection limits for the particular analyte.
  • Coolant gas flow should provide enough control resolution across a wide dynamic range to maintain system stability.

 

Axetris Advantages in ICP applications:

  • Extremely high repeatability of typically < 0.15% O.R.
  • Unmatched dynamic range (> 1000:1) to provide flexibility across wide flow range of 0-20 slpm
  • Ultra low flow control for tight control of plasma and analytical process
