We Are Heavy Metals
and Vitamin Testing

SGS is a world-class testing laboratory specializing in trace level elemental analysis. The Harrisburg site was established in 1995 and has provided testing through Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Inductively Couple Plasma-Optical Emissions Spectrometry (ICP-OES) since 1997. We are committed to the analysis of metals, minerals, other elements, small molecules, vitamins, and amino acids. It is with this dedication that we have emerged as a leader in elemental testing.

Quality and Clients Are Always Our First Priorities

We here at SGS pride ourselves not only on producing quality data, but also on consistently giving our clients excellent customer service. The quality of our service speaks best through our current clients, who have given us a Net Promoter Score of 91. We also do our absolute best to get clients their results when they need them. In fact, we meet or exceed our clients’ due dates 97% of the time and 99.3% of our reports go out the door with no errors.

Our People

With over 80 years of combined experience in analytical chemistry and trace level elemental analysis amongst our staff, you can be confident in the quality and accuracy of your data. Our familiarity with many different industries, including the environmental, pharmaceutical, industrial, specialty chemical, dietary supplement, cosmetic, and toxicological disciplines, has given us a broad understanding of a wide variety of sample types. SGS is uniquely qualified to take on your project or ongoing quality assurance testing.

Our Technology

SGS provides analysis through Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) for trace metal analysis and more. These techniques generally have less interference and are also faster than both Atomic Absorption (AA) and Graphite Furnace AA (GFAA) when analyzing for multiple elements in a single sample. Detection limits are usually lower than GFAA. Its productivity, accuracy, and precision at low levels, make ICP-MS and ICP-OES the predominant choices for research, regulatory, and quality assurance applications. Because of these features, SGS has the ability to analyze an abundance of matrices for most of the naturally occurring elements.

Our Commitment

At SGS we provide more than just trace level elemental analysis results. We believe in addressing all client needs personally and on an individual basis. Our entire staff is always available to answer all questions quickly and honestly. We also recognize that time is crucial so we make client response and turnaround time a priority. We consistently meet or exceed our clients’ due dates 97% of the time. We are proud of our Net Promoter Score, which is currently at 91.
