Chemical Pretreatment and Composition Analysis Preparation

Chemical pretreatment and composition analysis preparation refers to the series of physical and chemical processes applied to samples prior to instrumental measurement. These processes are essential for removing matrix interferences, extracting target analytes, converting samples into measurable forms, and ensuring compatibility with analytical instruments such as ICP-MS, ICP-OES, GC, HPLC, and spectrophotometers. Different sample matrices, such as pharmaceuticals, foods, environmental waters, soils, polymers, ceramics, and consumer products, require tailored pretreatment strategies. Improper or insufficient pretreatment can lead to analyte loss, contamination, inaccurate quantification, or poor reproducibility. Therefore, a robust and standardized chemical pretreatment system is fundamental to reliable analytical outcomes. Our chemical pretreatment and composition analysis preparation platform integrates automation, intelligent control, and validated methodologies to meet international testing standards. By combining advanced instruments with experienced technical teams, we are able to handle trace-level, ultra-trace-level, and complex matrix samples with confidence.
