LC-ICP-MS: The most often used hyphenated system for speciation analysis


Liquid chromatography (LC) is an extremely versatile technique with numerous advantages:
  • both the stationary phase and the mobile phase may be altered to achieve the desired separation,
  • separations can be further enhanced by the addition of additives (chiral additives, ion pair reagents, surfactants) to the mobile phase,
  • separations can be enhanced by changing the mobile phase during the analysis (gradient elution),
  • an enourmous variety of stationary phases are commercially available based on a rich variety of separation principles such as
    • normal phase chromatography (NPC)
    • reversed phase chromatography (RPC)
    • reversed phase ion pair chromatography (IPC)
    • micellar chromatography
    • ion exchange chromatography (IEC)
    • size exclusion chromatography (SEC).
  • Usually, minimum sample preparation is required.


Fig. 1 Coupling of HPLC with ICP-MS

Liquid sample introduction is the standard in ICP-MS, therefore coupling of liquid chromatography with ICP-MS in the simplest form is just the connection of the column outlet with the nebulizer of the sample introduction system via a transfer tubing.  It is not a surprise that the hyphenated system resulting from the coupling of liquid chromatography and ICP-MS is the most often used system for speciation analysis related to the ICP-MS detection. About 3/4 of all publications related to ICP-MS hyphenated techniques for speciation analysis describe the use of LC-ICP-MS.

Fig. 2: Development of publications related to LC-ICP-MS for speciation analysis

(Comment: After 30 years of development, the hyphenation of LC with ICP-MS has reached a level of maturity alloying its application in routine analysis. The number of publications  describing method development is therefore declining during the last years. Recent papers are focusing on optimising excisting methods for accuracy and sample throughput.)

LC-ICP-MS has important advantages for speciation analysis:

  • Complex chromatograms are reduced to simple "elementograms"
  • Quantification of even unknown element species is possible with respect to the detected element due to compound independent sensitivity without the necessity of having standards.
However the hard ionization and atomization power of the plasma source also has some drawbacks:
  • All molecular information is lost
  • Species characterization is limited to chromatographic retention times

Looking more closely onto the hyphenated system, some details have to be discussed:

  • contamination with metallic compounds arising from the chromatographic system (pump, valve, tubing) or the stationary and mobile phase,
  • dispersion effects, that means the influence on the sample introduction system on the separation power of the chromatographic system,
  • plasma solvent load effects, that means the influence on the mobile phase on the stability and ionization power of the inductively coupled plasma.

Plasma solvent load effects limit the free choice of the mobile phase, since now the mobile phase has to be selected both with respect to the separation task but also with respect to the degree of tolerance by the ICP. Tolerance by the ICP can be enhanced by reducing the flow-rate, which can be achieved by reducing the size-factor of the HPLC system from standard to micro-HPLC or even nano-HPLC. Tolerance of the ICP with nano-liter flow rates is so high that nearly any solvent can be introduced with total consumption nebulizers.

On the other hand, the negative influence of dead-volumes and other poor design factors on the chromatographic separation power is the more pronounced the smaller the flow rate of the system is.  Therefore, especially careful  design considerations are necessary for nano-HPLC coupling while standard system are less critical.

With respect to the type of MS detection system, one has to consider the transient character  of the chromatogtaphic signals. Depending on the number of simultaneous channels that have to be monitored (only one in the  simple case of a single element speciation), systems that can either simultaneously collect data on different channels or can do fast sequential measurements will have advantages.
