Ultratrace

Introduction

Ultratrace analyses in the environmental sector include dioxins, PCB congeners, and PAHs, all at the lowest of detection limits (ultratrace levels), due to the very high toxicity of various members of these classes of compounds.  Successful analyses at these low detection limits are demanding, and the technology involved is sophisticated.  When properly implemented, the accuracy and precision of ultratrace analyses using isotope dilution technology is state-of-the-art.

Getting the best accuracy and precision possible is no accident.  Our team understands the technology in depth and can pair that knowledge with your requirement to design the analysis that will best meet your needs and give you the most reliable data available in the industry.

Each analyte class has its own special nuances, but certain enhancements are common to all and include:

  • Using the maximum number of labeled standards that can practically be used, within commercial availability. This approach ensures the highest possible accuracy and precision.
  • Quality control samples that can specifically address the most critical steps of the analysis that traditional laboratory quality control samples cannot.
  • Ultra-low background levels to ensure contamination-free analyses.
  • Comprehensive data assessment that offers insights into the measurement beyond simply meeting QC criteria.

Our professionals monitor every step of the analysis (and potentially the sampling) to determine if and where losses occur.  Data assessment allows us to determine the best action to take to correct any problems with the sampling or analysis, leading to the delivery of the best possible data–faster.
