KOTITI provides highly reliable microplastic analysis services.

As microplastic pollution has recently become a serious social issue, there is a growing need for safety assurance and quality control across various industries. KOTITI, equipped with a clean system to prevent external contamination and skilled professionals, participates in numerous national research projects, including: the development and international standardization of microplastic evaluation methods for the textile industry; the development of precise microplastic analysis techniques for environmental samples; and distribution surveys of domestic river systems. Based on accumulated analytical expertise and data, KOTITI provides accurate and reliable microplastic analysis services.

What are Microplastics?

  • Defined as plastics intentionally manufactured or broken down into particles ≤5 mm.
  • They are difficult to degrade naturally, can travel long distances, and accumulate through the food chain, causing widespread environmental pollution.
  • Chemical components within microplastics and their degradation products have been reported to have direct and indirect effects.
  • Primary Microplastics
    Solid plastics (e.g., microbeads, pellets) intentionally manufactured in small sizes for product use
    (cosmetics, detergents, pharmaceuticals, agricultural and horticultural materials)
  • Secondary Microplastics
    Plastics unintentionally fragmented into small particles in the environment or during product use
    (tire wear, synthetic fiber washing, urban dust)
  • Microplastic Analysis Examples
  • Detection of microplastics in environmental samples
    환경 시료 내 미세플라스틱 검출
  • Detection of microplastics in textile wash water
    섬유 세탁액 내 미세플라스틱 검출

Targets for Microplastic Analysis

  • Drinking water, beverages (e.g., finished products, raw water)
  • Consumer chemical products (e.g., fabric softeners, laundry detergents)
  • Cosmetics (e.g., wet wipes, cleansing foam, shampoo)
  • Food products (e.g., salt, honey, snacks)
  • Textiles (e.g., fabrics, films, meat pads)
  • Containers (e.g., baby bottles, PET bottles)
  • Filters (e.g., water purifier filters, faucet filters)
  • Environmental samples (e.g., treated water, wastewater, river water)
