Qalitex Scales Global Lab Network with Validated Analytical Methods
An inside look at how Qalitex's method development and validation capabilities power a global testing network trusted by supplement and cosmetic brands for regulatory submissions.
Achieving amazon listing approval requires accurate, accredited laboratory testing that regulatory bodies and marketplace platforms trust. Qalitex Laboratories provides method development tailored for amazon listing approval requirements. Not every ingredient has a pharmacopeial monograph. When existing methods don't fit your product matrix, Qalitex Laboratories develops and validates custom analytical methods tailored to your specific formulation and regulatory requirements. Our ISO 17025 accredited methods and detailed COA reports are designed to streamline your amazon listing approval process.
How Method Development Supports Amazon listing approval
Amazon listing approval requires documented evidence of product safety and quality. Qalitex provides the specific testing and documentation needed to support your amazon listing approval process, including detailed COA reports, method validation documentation, and expert consultation on testing scope. Our ISO 17025 accreditation ensures your results are accepted by regulatory bodies and marketplace platforms.
Method Development Process
Our scientists start with a review of your product, target analyte, and regulatory requirements, then select the appropriate analytical platform (HPLC, GC, ICP-MS, etc.), optimize chromatographic conditions, and establish system suitability criteria. Development is typically completed in 2–4 weeks.
Method Validation (ICH Q2(R1))
Validation per ICH Q2(R1) includes: specificity/selectivity, linearity and range, accuracy (recovery studies), precision (repeatability, intermediate precision), limits of detection (LOD) and quantitation (LOQ), and robustness studies. A full Validation Report is provided for regulatory submission.
Method Transfer
If you are bringing an existing validated method from another laboratory, we perform method transfer studies to confirm the method performs equivalently in our laboratory under ISO 17025 conditions.
