Trace Metals Analysis

Trace metals analysis is critical in various industries whose presence can impact toxicity and product performance, such as:

  • Chemicals, catalysts, pharmaceuticals, environmental, agricultural, cosmetic, consumer products
  • Metals analysis is also required during various stages of product development in manufacturing to identify metal contaminants.

Using advanced instrumentation such as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Graphite Furnace Atomic Absorption Spectroscopy (GFAAS) LSAI has the capability to detect, identify and quantitate extremely low levels of metals ranging from parts per million (ppm) to parts per billion (ppb) and sub-ppb levels of in a wide variety of materials.

LSAI has state-of-the-art microwave digestion instrument. Microwave Digestion is a sample preparation technique where the sample is decomposed and digested in a sealed vessel under high temperature and pressure causing the metals to release and dissolve into the aqueous solution for trace analysis.

LSAI can perform low-level Mercury analysis up to parts per trillion (ppt) concentrations via cold vapor atomic fluorescence spectroscopy (Hg-CVAFS). Several EPA methods 7471, 7473, 7474 can be analyzed at LSAI. EPA has a 2 ppb or 2 µg/L limit for mercury in drinking water and the cold vapor fluorescence technique can quantify mercury at such levels.

LSAI has trained scientists proficient in method development and validation. We comply with USP 232 or 233 for heavy metals analysis.
