Description

Ochratoxin A 13C20 Solution is a high-purity, isotopically labeled analytical standard essential for accurate mycotoxin quantification and method validation. This certified reference material is critical for ensuring data integrity in sensitive detection workflows, providing a stable internal standard to correct for analyte loss and matrix effects. It is primarily required by analytical laboratories and quality control departments in the food safety, agricultural, and biomedical research sectors for precise LC-MS/MS analysis.

Application

• Use as an internal standard for the quantitative analysis of Ochratoxin A in food and feed matrices via LC-MS/MS.
• Critical component in method development and validation for regulatory compliance testing (e.g., EU, FDA).
• Calibration and quality control in clinical and diagnostic research involving mycotoxin exposure biomarkers.
• Metabolic and toxicological studies requiring stable isotope-labeled tracers for accurate pharmacokinetic profiling.
• Proficiency testing and laboratory accreditation programs to ensure analytical consistency across labs.
• Reference material for the certification of matrix-matched certified reference materials (CRMs).

Quality Control

Every batch of our Ochratoxin A 13C20 Solution is manufactured and certified to the highest standards for isotopic purity and chemical identity. Quality is assured through rigorous analytical testing including NMR for isotopic enrichment verification and HPLC-MS for chemical purity and absence of unlabeled contaminant. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing batch-specific data on concentration, solvent, isotopic purity (typically >99 atom% 13C), and chemical purity. Our quality system supports compliance with ISO 17034 and ISO/IEC 17025 requirements for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below. The solution is prepared in a strong acid/organic solvent mixture; handle with appropriate precautions in a well-ventilated area. For long-term stability, avoid repeated freeze-thaw cycles and store the primary container in a dedicated freezer.
