METALS ANALYSIS
We use a variety of methodologies to perform metals analysis including
inductively
coupled plasma atomic emission spectroscopy (ICP), atomic
absorption (AA), gaseous hydride AA
(GHAA) and cold vapor AA (CVAA) .
Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP)
The following elements are routinely available by ICP:

|
Other elements may be available by ICP. Inquire
for details.
Inductively Coupled Plasma Mass Spectroscopy ICP/MS
Most elements from atomic mass 6 to mass 238 can be determined by this
technique. In clean matrices such as deionized water, detection limits
are sub
part per billion (µg/l) for the majority of elements. Available
elements and actual detection limits vary with sample matrix and required
sample decomposition.
Please inquire as to
the best approach for your particular samples and analytical requirements.
