Analytical Chemistry
Tiny Compounds. Massive Consequences.
In analytical testing, every result begins with a reference standard. The ampul may be small, but its impact on calibration, traceability, and data confidence is substantial.
Your Data Starts With the Standard
A calibration curve is only as reliable as the material used to create it. Whether a laboratory is testing environmental samples, food products, or cannabis, the quality of the reference standard affects the accuracy and defensibility of every reported result.
Poorly characterized or unstable standards can introduce uncertainty long before a sample reaches the instrument. For this reason, laboratories should consider purity, stability, documentation, traceability, and suitability for the intended method—not simply concentration and price.
Why Restek Reference Standards?
Restek manufactures reference standards for laboratories that require dependable performance in regulated and routine analytical workflows. Its reference-standard manufacturing and quality-control laboratories in Bellefonte, Pennsylvania hold ISO 17034 and ISO/IEC 17025 accreditations.
This supports a controlled process from raw-material characterization and formulation through testing, packaging, stability evaluation, and documentation. Restek also manufactures chromatographic columns and sample-preparation products, giving laboratories access to a more integrated analytical workflow.
Designed for Demanding Applications
Restek offers standards for environmental, food, pharmaceutical, forensic, and cannabis testing applications. Laboratories can select individual compounds, multicomponent mixes, certified reference materials, and custom formulations based on their method requirements.
- Environmental contaminants, including PFAS and pesticides
- Food safety compounds, mycotoxins, and processing contaminants
- Cannabinoids, terpenes, residual solvents, and pesticides
- Custom blends for specialized methods and analyte lists
Confidence Beyond the Ampul
Reliable analytical work depends on more than a properly functioning GC or LC system. It requires a standard supported by clear documentation, demonstrated stability, and appropriate traceability.
In practical terms, the reference standard is not just another laboratory consumable. It is the foundation of the measurement.
