Core Analytical and Contract Testing Capabilities

International Research Institute of Natural Products, or International RINP, stands out for its deep bench of veteran scientists and its adherence to recognized global methodologies (including USP, AOAC, AOCS, BP, and CP), alongside custom method design. Their core expertise spans several critical analytical disciplines:

  • Deformulation & Reverse Engineering: Deconstructing complex commercial products to isolate, identify, and quantify active ingredients, excipients, and specific additives. This service is foundational for clients resolving patent disputes, evaluating competitor formulations, or optimizing existing products.
  • Botanical Characterization & Natural Products R&D: Providing specialized, high-resolution validation for the dietary supplement industry. This includes authenticating botanical species, establishing reliable active markers, and safely isolating active compounds from complex plant matrices.
  • Contaminant & Unknown Material Identification: Isolating and identifying chemical impurities, particulates, or unexpected degradation products. Using advanced molecular spectroscopy, the lab uncovers the root cause of manufacturing anomalies or contamination events.
  • Method Development & Validation: Designing, refining, and validating custom analytical protocols. Every method is built to ensure accuracy, specificity, linearity, and robustness, meeting the exact criteria required for regulatory submissions.

Advanced Service Verticals & Specialized Assays

In addition to traditional chemical analysis, International RINP maintains a diversified testing footprint capable of executing highly specialized, high-complexity assays. These specialized capabilities include:

  • Targeted Bioactive Assays: Quantitative analysis of intricate organic compounds, such as isolating and measuring specific neurological components (erinacines and hericenones) in organic mushroom and fungal extracts.
  • Purity & Adulteration Screening: High-sensitivity testing for regulated compounds across consumer products, including the screening and quantification of restricted topical corticosteroids in commercial cosmetics and skincare creams.
  • Physical & Metallurgical Characterization: Structural and elemental testing tailored to the distinct needs of the medical device, mining, and metallurgy sectors.
