Analyzing Multiresidue Pesticides Using QuEChERS - Fundamentals
HTML-код
- Опубликовано: 22 авг 2024
- The fundamentals of multiresidue pesticide analysis using the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) technique are discussed, including the step-by-step process. This technique has revolutionized multiresidue, multiclass pesticide analysis. There are three main methods for use for multiresidue pesticide analysis: Original (containing non-buffered salts), the Association of Official Agricultural Chemists (AOAC) Method, and the European Standard (EN) Method. This video mainly focuses on AOAC. The first step is Extraction/Partitioning (Acetonitrile salting-out extraction of a sample), the second step is clean-up of the extract using Dispersive Solid Phase Extraction (dSPE), and the final step is to analyze the results.

How to extract pesticides from oils and fats?
Please provide notes.
after the d-SPE step, Ms. Joan pippetted the ACN layer direct to vial without filtering with 0.22um filter, I wonder that the final extract is really clear without solid particle that can harm the LC system?. Do we need to add filtering step on this experiment?
If filtration is used, one would need to be sure analytes are not lost during the filtration process. We do not filter any extract after dSPE, but we do use a guard column.
I wonder what these guys are up to these days
very nice explanation
Sir iam searching for gulf coutry please sugest me
For job
how to extract pesticide from saliva ? is the quechers method can solve it?
Aren’t the salts used (Na, Mg) not mass spec compatible? Even with centrifuging, you can’t really ensure all salts were removed to an acceptable level.
"example of the sample" god i can only imagine how many takes that sentence required ^_^
How to extract carrot sample if there is any method to avoid losing any analyte after clean up
From where can we get the notes?
