The auxiliary experimenters significantly improve the efficiency of data processing. For example, a sample needs to be tested for more than 200 pesticide residues simultaneously. Assuming a batch of 20 samples, a total of about 40-100 pesticide residues are detected (2-5 pesticides are detected in each sample). If iTAS software is used to assist in data processing, after manually interpreting the spectrum, it only takes 5-10 minutes to complete sample concentration calculation, regulatory interpretation, and report production, which increases efficiency by 10 times.

This article will introduce two methods for sugar detection in meat products: Method 1: Purification using a Giant Research FaAEx-AD2 sugar specific SPE column and analysis using LC/ELSD method; Method 2: Refer to the GB/T 9695.31-2008 method and analyze using spectrophotometry and direct titration

This scheme provides a reliable, sensitive, and reproducible analysis method for 183 veterinary drug residues in animal derived food matrices. The sample pretreatment adopts the FaVEx rapid extraction column purification method, and the SPE column does not require activation equilibrium. The sample extraction solution only needs to be purified in one step through the SPE column. The instrument analysis adopts the Agilent 1260/1290 Infinity II UHPLC System (rapid mass spectrometry analysis scheme~24 minutes), which simplifies the detection of veterinary drug residues, and the analysis results meet the standard requirements.

The State Administration for Market Regulation has clear regulations on the technical requirements and application of "food rapid testing". This article compares the "Application Plan for Mass Spectrometry Rapid Testing of 198 Types of Vegetable and Fruit Pesticide Residues" with its regulations, and explains how to use mass spectrometry rapid testing technology to catch more unqualified vegetables and fruits with excessive pesticide residues, thereby improving their "unqualified rate".

The mass spectrometry rapid detection method for 373 pesticide residues and the rapid extraction method for pesticide residue detection in food are applicable for multiple residue analysis of 373 pesticides in foods such as fruits and vegetables, grains, dried beans, tea, spice plants, and other herbaceous plants.
