Un-known Sample (Advanced Component Analysis)

Unknown substances incorporated into products such as industrial equipment and components, raw materials, food, pharmaceuticals, and cosmetics.


The analysis of unknown samples is complex because the target of analysis is unclear, leading to a variety of analytical methods and approaches. We support the analysis of unknown samples using various instruments such as TGA-FT-IR, XRD, GC-MS, LC-MS/MS, and ICP-MS. Due to the high level of difficulty involved, this analysis requires the in-depth judgment of researchers and the application of advanced analytical techniques to achieve more accurate results.


Analysis Procedure

  • - Data Collection : Review related data such as the physical characteristics of the sample, its intended use, the purpose of analysis, and the manufacturing process.
  • - Selection of Analytical Methods : Choose the appropriate analytical methods based on the collected data.
  • - Expert Interpretation : Identify the unknown sample through in-depth interpretation.
  • We can accurately determine the characteristics of unknown samples incorporated into various products. Through the analysis of unknown samples, we provide reliable data to our clients, contributing to the assurance of product quality and safety. Based on extensive expertise and experience, we offer optimized solutions for various analytical needs.
Analysis Period : 5 to 10 business days
