The elegant design of the Elegra results in a very compact accessory (Figure 1), making it easy to fit every ICP model without overcrowding the sample compartment. The Elegra utilizes highly efficient membrane technology to add moisture to the argon as it flows through the inert metal-free construction. The device runs at atmospheric pressure and does not require heating or electric power. The Elegra is also configured with a bypass switch so that the operator can turn humidification on and off without connecting or disconnecting any tubing. For easy installation on any ICP instrument and nebulizer, each Elegra Kit is packaged with customized gas connectors.

Two of the most significant areas of advancement in inductively coupled plasma-mass spectrometry (ICP-MS) with respect to clinical applications have been the evolution of the sample introduction system and the interface of liquid chromatography (LC). The complexity of the sample matrix creates challenges for a number of components involved with the introduction of ions into the mass spectrometer, including the nebulizer, spray chamber, torch, and interface cones. The development of LC-ICP-MS methods enables analysts to quantitate not only the total metal content but the form of the metal as well, a distinction that in many cases is crucial. Although the refinement of reaction and collision cell technology has been important for this application, much has been written elsewhere and it will not be addressed here.
