We would like to introduce the analysis of "Alternative Plasticizers for Phthalate Esters in PVC" conducted by Ronbic Co., Ltd. In addition to the four types of phthalate esters (DEHP, BBP, DBP, DIBP) added to the list of designated harmful substances under the RoHS Directive, and phthalate esters subject to REACH regulations, we can qualitatively and quantitatively analyze compounds used as plasticizers for polyvinyl chloride (PVC). Please feel free to contact us if you have any inquiries. [Types] ■ Diester of adipic acid ■ Diester of sebacic acid ■ Triester of trimellitic acid *For more details, please download the PDF or feel free to contact us.

We would like to introduce our analysis of "Pentaerythritol-based surfactants (antistatic agents)." Pentaerythritol fatty acid esters are used as nonionic surfactants (non-ionic antistatic agents) in resins such as polyethylene, and are also used as additives in a wide range of fields including lubricants, paints, and cosmetics. Through instrumental analysis using GC/MS and HPLC, it is possible to qualitatively and quantitatively analyze each component and calculate the purity (composition ratio). 【HPLC Measurement Example】 ■ Pentaerythritol stearate - A compound in which stearic acid (and the impurity palmitic acid) is bonded to 1 to 4 molecules of pentaerythritol. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Quantitative Analysis of High Molecular Weight HALS" conducted by Ronbic Co., Ltd. Quantitative analysis of high molecular weight hindered amine light stabilizers (HALS) in resins (plastics) is possible. We provide information related to quantification, such as confirming the formulation amount in products (molded items) and checking the content after actual use in the field (outdoors). [Provided Information] ■ Confirmation of formulation amount in products (molded items) ■ Confirmation of content after actual use in the field (outdoors) ■ Other information related to quantification *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Qualitative and Quantitative Analysis of Metal Soaps (Metal Salts of Fatty Acids)" conducted by Ronbic Co., Ltd. Analysis of metal soaps (metal salts of fatty acids), which are used in various applications such as stabilizers, lubricants, release agents, filler and pigment dispersants, vulcanization accelerators, and curing agents, is possible. Direct analysis of metal salts of fatty acids is difficult, but qualitative and quantitative analysis can be achieved by analyzing the metal components and fatty acid components separately. 【Example of Detected Components】 ■Ca (Calcium) ■Mg (Magnesium) ■Lauric Acid ■Behenic Acid ■12-Hydroxystearic Acid *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Additive Analysis in Resins" conducted by Ronbic Co., Ltd. We have established an analysis database with over 800 types of resin additives, enabling qualitative and quantitative analysis of a wide variety of additives in resins. We will propose analysis designs suitable for the types of resins and additives. Please feel free to consult us when you need our services. 【Examples of Requested Projects】 ■ Part of quality control: Confirmation of blending amounts in products (molded items), etc. ■ Assistance in product development: Confirmation of content after use, investigation of competitor products, etc. ■ Investigation of causes of troubles (such as molding and appearance defects), etc. *For more details, please download the PDF or feel free to contact us.
