Introduction

Standard Technical Analysis

The core detection objects include 6 common plasticizers such as DMP, DEP, DBP, etc., with a focus on high-risk substances such as di(2-ethylhexyl) phthalate (DEHP).

Methodological Comparison

Technical Parameters	Ultrasonic Extraction Method	Traditional Soxhlet Method
Processing Time	30min	More than 8h
Solvent Consumption	70ml Mixed Solvent	250-400ml
Recovery Deviation	±5%	±15%

Technical Evolution Path

Compared with the 2010 version of the agricultural industry standard, the main improvements of this standard are reflected in:

Add a silica gel column separation step to the purification process
Use SIM mode for mass spectrometry to improve sensitivity
Reduce the detection limit of DBP from 0.1mg/kg to 0.07mg/kg

Practical guidance suggestions

Operation tips:A blank control should be performed before testing the gas chromatography-mass spectrometry. It is recommended to clean the injection needle with acetone after each injection to prevent cross contamination.
