Application Note: Inductively Coupled Plasma Spectroscopy

From Hamilton Co.
 

 

Inductively Coupled Plasma Spectroscopy (ICP) is used to detect trace metals from environmental samples. Three concentric tubes make up what is known as the torch.
The torch is surrounded by the water cooled coil of a radio frequency (r.f.) generator. As gasses flow through the system the r.f. field is activated which results in the formation of the plasma. Sample is introduced to the plasma through the carrier gas which is commonly Argon. Light emitted by elements in the sample can be detected and used to determine concentrations of unknowns in the sample.

ICP Sample Preparation with the ML500 diluter:
The ML500 is used to make standards, perform acid digestions, and sample dilutions for ICP. The instrument eliminates the need for glass pipettes and volumetric glassware for large and small ratio dilutions (1:1 to 1:25,000 in a single step). The fluid path is made from Borosilicate Glass and PTFE that resists harsh chemicals and minimizes sample carryover. The low sample carryover makes the ML500 ideal for ICP and ICP-Mass Spectrometry.
