Present in resins, oils, or composites, it plays a key role in the thermal resistance, heat stability, and durability of materials. ### Our organic additive analysis services [Analysis of Irgafos 168 (CAS No. 31570-04-4)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-irgafos-168.md) [Analysis of Chimassorb 944 (CAS No. 71878-19-8)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-chimassorb-944.md) [Analysis of DBP (dibutyl phthalate) CAS No. 84-74-2](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-dbp.md) [Analysis of TOTM (trimellitate) CAS No. 3319-31-1](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-totm.md) [Analysis of Irganox 1010 (CAS No. 6683-19-8), Irganox 1076 (CAS No. 2082-79-3), Irganox 3114 (CAS No. 27676-62-6)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-additives-irganox-1010-1076-3114.md) [Analysis of Tinuvin 770 (CAS No. 52829-07-9), Tinuvin 622 (CAS No. 65447-77-0), Tinuvin 327 (CAS No. 3864-99-1), Tinuvin 328 (CAS No. 25973-55-1), Tinuvin P (CAS No. 2440-22-4)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-tinuvin.md) [Analysis of BHT (butylated hydroxytoluene) CAS No. 128-37-0](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-bht-cas-128-37-0.md) ## FILAB meets your needs for Triphenyl phosphite (TPP) CAS No. 101-02-0 analysis ### Our technical resources for the analysis of Triphenyl phosphite (TPP) CAS No. 101-02-0 [### HPLC To separate and quantify the TPP from the other ingredients in the formula](https://filab.fr/en/our-technical-resources/laboratory-analysis-uplc.md) [### GC-MS To identify and quantify the TPP](https://filab.fr/en/our-technical-resources/laboratory-analysis-gcms.md) [### LC-MSMS To detect and quantify traces of TPP or its degradation products](https://filab.fr/en/our-technical-resources/altis-lc-msms-analysis.md) [### FTIR For rapid qualitative analysis on samples of pure TPP or in the raw material](https://filab.fr/nos-moyens-techniques/laboratoire-danalyses-chimiques-par-irtf-ftir.md) ## Why choose FILAB for the analysis of organic additives: Triphenyl phosphite (TPP) CAS No. 101-02-0 For over ten years, the FILAB laboratory has developed extensive expertise in c[hemical analysis](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory.md).

TPP analysis allows you to: - Verify the conformity of a supplier batch - Control the actual additive content in the final formulation - Identify a loss of thermal stability - Understand a product defect (yellowing, brittleness, rapid oxidation) - Monitor the material's evolution during aging tests In which materials can Triphenyl phosphite be analyzed? Analysis is possible on: - Plastics and polymers (PE, PP, PET, PVC, TPU, elastomers, etc.) - Thermoplastic or thermosetting composites and resins - Oils, lubricants, and technical fluids - Liquid or solid additives - Inks, varnishes, adhesives, and coatings Can your laboratory detect low levels of TPP? Yes. The methods in place allow for the analysis of TPP at very low levels (traces), and up to the percentage level in concentrated formulations. The exact threshold will depend on the matrix and the technique used. Is it possible to analyze several additives at the same time (phosphites, phenolics, antioxidants)? Yes. It is perfectly possible to dose TPP in parallel with other common additives (Irgafos, Irganox, HALS…), which allows for a global view of the formulation. Can the laboratory develop a specific method for TPP? Yes. If your matrix is ​​complex or you require a specific detection limit, we can design and validate a tailor-made method adapted to your industrial constraints.
