A new method uses Solid-Phase Microextraction (SPME) to detect DDVP in white spirits. This solvent-free technique offers sensitive and efficient chemical analysis.

Area of Science:

Analytical Chemistry
Environmental Science

Context:

White spirits can be contaminated with harmful chemicals.
Accurate detection of contaminants is crucial for safety.

Purpose:

To develop a sensitive and efficient method for DDVP detection in white spirits.
To utilize Solid-Phase Microextraction (SPME) for sample preparation and analysis.

Summary:

Dichlorvos (DDVP) was isolated from white spirits using Solid-Phase Microextraction (SPME).
Analysis was performed using gas chromatography (GC) with a flame ionization detector.
The method demonstrated excellent linearity (0.5-12 mg/L), high correlation coefficient (0.9983), and a low minimum detectable concentration (0.05 mg/L).
This integrated, solvent-free process streamlines extraction, enrichment, and injection.
