The accurate detection and quantification of agrochemicals like Diclosulam are fundamental to ensuring product quality, regulatory compliance, and environmental safety. As a dedicated manufacturer and supplier of Diclosulam in China, we employ sophisticated analytical methodologies to guarantee the integrity of our products and to support research and regulatory requirements.

Advanced Analytical Techniques for Diclosulam

The analysis of Diclosulam, a herbicide belonging to the triazolopyrimidine sulfonanilide class, typically relies on highly sensitive chromatographic techniques. These methods are crucial for detecting residual amounts in various matrices, such as soil, water, and plant tissues, as well as for ensuring the purity of the manufactured product.

  • High-Performance Liquid Chromatography (HPLC): HPLC, often coupled with UV-Vis or Photodiode Array (PDA) detectors, is a primary method for Diclosulam analysis. Reverse-phase HPLC with mobile phases like acetonitrile and phosphoric acid is commonly used. This technique offers excellent sensitivity and selectivity, allowing for the precise quantification of Diclosulam residues with high recovery rates (often above 85%).
  • Gas Chromatography-Mass Spectrometry (GC-MS): While HPLC is generally preferred for Diclosulam itself, GC-MS is invaluable for identifying and quantifying its metabolites, which may have different volatilities. GC-MS provides definitive identification through mass spectral data and is used for tracing the herbicide's degradation pathways.
  • Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS): This advanced technique offers even greater sensitivity and specificity, making it ideal for detecting trace levels of Diclosulam in complex matrices. It is widely used in environmental monitoring and residue analysis.

Method Validation and Quality Assurance

Ensuring the reliability of analytical data is paramount. Our analytical processes adhere to rigorous method validation and quality assurance (QA) protocols, typically following guidelines such as SANTE/11312/2021. Key validation parameters include:

  • Specificity: Confirming that the method accurately measures Diclosulam without interference from other compounds.
  • Linearity: Establishing a proportional relationship between analyte concentration and instrument response, with high correlation coefficients (R² > 0.995).
  • Accuracy: Determined through recovery studies, where known amounts of Diclosulam are spiked into blank samples. Acceptable recovery ranges are typically between 70% and 120%.
  • Precision: Measured as relative standard deviation (RSD), ensuring consistent results across multiple analyses, with acceptable RSD values often below 20%.
  • Limits of Detection (LOD) and Quantification (LOQ): Establishing the lowest concentrations at which Diclosulam can be reliably detected and quantified.

Routine quality control samples, system suitability tests, and the use of certified reference standards are integral parts of our QA system. This meticulous approach guarantees the quality and safety of the Diclosulam we supply.
