We would like to introduce the "Pyrolysis GC/MS Analysis" conducted by Ronbic Co., Ltd. We can analyze a variety of materials in different forms, from liquids to solids, including plastics, rubber, wood, fibers, paints, inks, adhesives, and oils. By directly introducing the sample and performing pyrolysis followed by separation analysis using GC/MS, we can analyze materials that are insoluble in solvents, such as cross-linked polymer materials and thermosetting resins. 【Analysis Conditions】 ■ Sample Amount: 0.1 mg to several m ■ Temperature Range: 40 to 800℃ ■ Heating Atmosphere: He *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Reaction Thermal Decomposition GC/MS Method for Structural Analysis of Liquid Crystal Polymers" conducted by Ronbic Co., Ltd. Even in the case of condensation-type polymers that contain ester bonds, it is possible to estimate the structure by performing thermal decomposition with the coexistence of derivatization reagents using the reaction thermal decomposition GC/MS method. Please feel free to consult us when needed. 【Features】 ■ Thermal Decomposition GC/MS Method - Estimating the structure is difficult with peaks of polar compounds only. ■ Reaction Thermal Decomposition GC/MS Method - Methylated forms of the constituent monomers are observed. - Structural estimation is possible even for condensation-type polymers that contain ester bonds. *For more details, please download the PDF or feel free to contact us.

Our company is capable of qualitative and quantitative analysis of outgassing using static headspace GC/MS by sealing samples in glass vials. If solvents or unreacted materials remain in the product's resin materials, packaging materials, or cushioning materials, they can diffuse as outgassing (volatile gases). This can not only cause defects in the product but may also have adverse effects on the environment and human health. Our company possesses analytical know-how, including sample handling. Please feel free to consult with us. 【Sample Handling Instructions】 ■ Avoid direct contact with samples using bare hands and do not place them directly into plastic bags. ■ Powdered samples, liquid samples: Pack tightly in glass screw-cap bottles to eliminate air space and seal with a lid that has a fluororesin-coated gasket. ■ Film (sheet) type, plate type samples: Wrap them so that the matte side of the aluminum foil is in contact with the sample, ensuring there is no air space. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Composition Analysis of Mixed Resin Materials such as Recycled Plastics" conducted by Ronbic Co., Ltd. Qualitative and quantitative analysis of the following 12 types of polymers in mixed resin materials is possible: PE/PP/PS/ABS/SBR/PMMA/PC/PVC/PU (MDI-based)/PET/Ny6/Ny66 Additionally, without the need for complex separation processes or multiple analytical instruments, composition analysis of various samples such as recycled plastics (related to recycling) can be performed using thermal decomposition GC/MS methods. 【Composition Analysis】 ■ Recycled Plastics (related to recycling) ■ Waste Plastics (related to waste recycling) ■ Polymer Blends (related to synthetic resins) ■ Microplastics (related to marine pollution) *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Quantitative Analysis of Paraffin Oil in Thermoplastic Elastomers" conducted by Ronbic Co., Ltd. Quantitative analysis of paraffin oil in a wide variety of thermoplastic elastomers (TPE), including styrene-based, olefin-based, urethane-based, ester-based, and amide-based, is possible. We will propose an analysis design suitable for the type of TPE. [Types] ■ Styrene-based ■ Olefin-based ■ Urethane-based ■ Ester-based ■ Amide-based *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "SEC (GPC, APC) analysis" conducted by Ronbic Co., Ltd. Measurements can be performed using various solvent systems such as THF (Tetrahydrofuran), HFIP (Hexafluoroisopropanol), and DMF (N,N-Dimethylformamide). Examples of causes for abnormalities in molded products include insufficient drying of raw materials and abnormal molding conditions, which can lead to a decrease in molecular weight and insufficient strength of the molded products. 【Examples of measurable solvents】 ■ THF (Tetrahydrofuran) ■ HFIP (Hexafluoroisopropanol) ■ NMP (1-Methyl-2-pyrrolidone) ■ Cyclohexane ■ Chloroform ■ DMF (N,N-Dimethylformamide) *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "HPLC analysis" conducted at Ronbic Co., Ltd. As examples of equipment, we use the "Corona Charged Aerosol Detector" which can sensitively detect components without UV absorption (more sensitive than RI and ELSD), and the "Photodiode Array Detector (PDA)" which can sensitively detect components with UV absorption (190–800nm). Please feel free to consult us when you need our services. 【Equipment Examples】 ■ Corona Charged Aerosol Detector ■ Photodiode Array Detector (PDA) *For more details, please download the PDF or feel free to contact us.

"Chromatographic analysis" is a method for separating and analyzing components of a mixture. When a mixture sample is injected into a column through which a fluid is flowing, the mixture is separated into its components due to chemical and physical interactions as it moves through the flow. Each component is converted into an electrical signal by a detector and is represented as a peak (chromatogram). [Types] ■ Gas Chromatography - Uses gases such as nitrogen or helium. ■ Liquid Chromatography - Uses liquids such as organic solvents or water. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a molecular weight evaluation technology for cellulose materials. It enables the dissolution of difficult-to-dissolve cellulose in a short time and allows for the measurement of molecular weight distribution using GPC. Our unique pretreatment technology achieves the preparation of stable solutions suitable for rapid dissolution and GPC measurement. Additionally, we have accumulated know-how regarding resin separation technology, allowing us to isolate cellulose nanofibers (CNF) from composite materials and measure their molecular weight distribution. 【Measurement Example: Cellulose Molecular Weight Distribution】 ■ Our unique pretreatment technology enables the preparation of stable solutions suitable for rapid dissolution and GPC measurement. ■ The presence or absence of cellulose degradation before and after molding of composite materials, as well as during recycling, can be evaluated from changes in molecular weight distribution. *For more details, please download the PDF or feel free to contact us.
