Precious Metals
Luvak provides accurate, traceable analysis of precious metal composition and purity for gold, silver, and the platinum group metals. As an ISO/IEC 17025 and Nadcap-accredited laboratory with more than 50 years in materials testing, we support refining, manufacturing, and quality control where composition carries real value.
What We Test for Precious Metals
Luvak provides accurate, traceable analysis of precious metal composition and purity for gold, silver, and the platinum group metals. As an ISO/IEC 17025 and Nadcap-accredited laboratory with more than 50 years in materials testing, we support refining, manufacturing, and quality control where composition carries real value.
Our Analysis Methods
ICP Elemental Analysis
Inductively coupled plasma optical emission spectroscopy (ICP-OES) to ASTM E2371, E1479, E2594, and E3061.
A versatile, efficient method run on the SPECTRO ARCOS FHX22, providing one of the most accurate testing methods available today.
DCP Elemental Analysis
Direct current plasma emission spectroscopy (DCPES) to ASTM E1097 and E2371.
A classic optical method run on the Beckman Spectra Span VI, backed by more than 30 years of experience.
Atomic Absorption Spectroscopy
Flame atomic absorption (AA) spectroscopy to ASTM E663.
Less prone to spectral interference, AA provides accurate detection of trace metals using the Perkin Elmer 3030B.
Graphite Furnace Atomic Absorption
Graphite furnace atomic absorption (GFAA) to ASTM E1184.
An electric furnace and multiple heating steps remove interferences and isolate the target element, giving sub-ppm determination of trace metals on the Shimadzu AA6650.
