Clark Testing provides ICP (Inductively Coupled Plasma) Spectroscopy for elemental analysis to identify and measure chemical elements within a sample matrix to the trace and ultra-trace levels.

Equipment & Industries

Clark’s ICP Analysis Laboratory is home to two state of the art ICP-OES (or optical emission spectroscopy) instruments. ICP-OES analysis measures a wide variety of elements by identifying the wavelength of light emitted from each sample, comparing that to standards run on the instrument. Because of the range of analyses of ICP-OES, it is a go-to method for determining the composition of materials in the industrial & household chemistry, mining & raw materials, coal & coke, and lubrication industries. It also serves in validating materials in newer industries such as rare earth elements and battery & energy storage.

ICP Laboratory Services

Because of Clark’s depth of expertise, and capacity of equipment, we offer both experimental or exploratory analysis by ICP as well as consistent, repetitive testing. We also offer sample handling and preparation services and report consulting throughout the process, should you need help understanding the basics of ICP or more in-depth interpretation of produced results.

Sample Preparation & Results

Clark conducts trace analysis on both solids and liquids. Solid material is first cut, crushed and/or milled to create the sample size. The material is then digested into a liquid solution and analyzed by ICP for the elemental composition. Each element is reported individually. The methodology utilized is determined by the material being tested; notably acid digested and/or fusing with a borate flux.  Liquids are digested and analyzed in a similar manner.

Results are reported as either Elemental or Elemental Oxides, depending on the material being analyzed. ICP-OES can produce results by percent-weight (%-wt) or in parts per million (PPM).

Typical:  Al, Ag, As, Ba, Be, Cd, Cr, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Si, Sn, Ti, V, W, Zn
