Accurate quantitation
GC/MS or LC/MS/MS batches include calibrators at different concentrations, typically at least three points, to support the most accurate quantitation possible.
Strict quality review
Controls within analytical batches include negative and positive samples. Results are subjected to strict acceptance criteria and plotted on Levi-Jennings charts for comparison.
Pharmaceutical support
In addition to drugs of abuse work, ELI provides GC/MS, HPLC, and LC/MS/MS analytical services to pharmaceutical clients, from method development to specimen analysis.
