Pesticide Residue Analysis | Sample Preparation | Extraction and Cleanup | USEPA 3620C

The Pesticide residue has been the most demandable test all over the world for food, especially fruits and vegetables. Gas Chromatography is the most widely adopted technique in pesticide residue analysis. Pesticides that are amenable to direct analysis by means of GC should preferably be determined by means of this method because it separates well, is fast, and has available many selective and sensitive detectors. This video is developed to show you in details about the sample
preparation for pesticide residue analysis of vegetable samples.

You are great !!! Thanks for uploading this kinds of video which are rare in KZbin. These videos are very helpful for laboratory analysts.

[@MicroChemsExperiments]

It's my pleasure

[@MerazulMomenin-u4f]

I am a researcher of an institute. For this video I waited so long, thanks.

[@MicroChemsExperiments]

Glad it was helpful!

Helpful video. How to remove the pesticide residues/reduce from fruits & vegitable etc.

[@KenwasiFFYT]

Great video. KZbin does not have this kinds of video except yours. Thanks for making this.❤❤❤

[@MicroChemsExperiments]

Welcome. Stay with us.

[@nashwarasheeda]

thank you! is this also aplicable for meat analysis?

[@madhusmita1131]

Hey, thank you . I would like to know, is it applicable for PAH analysis??

[@MerazulMomenin-i4o]

Superb. You made easy to determine the pesticide residue.

[@MicroChemsExperiments]

Is this method of extraction different from QuEChERS? the video is very clear,thank you very much

[@MicroChemsExperiments]

Yes. QuEChERS method is different

[@alejandrocarmonahernandez455]

I have a doubt about how the calibration curve was made for that method, it is only done in solvent?...should some correction be made for the determination of the concentration?

[@tasyanurafifahsyifafitriya3144]

i can't wait your new video, but can i request something? please make video about MPN analysis , thank you mam

[@MicroChemsExperiments]

Noted. We will make it soon. Stay with us.

[@MerazulMomenin-b5z]

Very informative video. Keep it up. May I ask what type of fruits and vegetables can be analyzed with this method? Thank you in advance.

[@MicroChemsExperiments]

All kinds of fruits and vegitables

Hi im interested in detecting the presence of aromatic compounds in soil sample ! So in silica gel purification column ,i will have to use florosil and sodium sulphate only ?

[@MicroChemsExperiments]

Yes

[@mst.anikaakter4061]

thanks for the video. Can I use Petroleum ether instead of n-Hexane?

[@MicroChemsExperiments]

Yes. You can

[@MerazulMomenin]

Nice Video. Very Helpful

[@gandianusha4131]

Can use acetonitrile instead of n hexane

[@MicroChemsExperiments]

No. In this procedure acetonitrile will not work because of Florisil. You must use n-Hexane

[@MerazulMomenin-j1q]

Thanks

[@MicroChemsExperiments]

No problem

[@klipjiang4422]

Why dilution factor is 2? Thanks

[@MicroChemsExperiments]

The dilution factor should be 0.5 (Final Volume/sample weight=10ml/20g=0.5)

[@blissidoko302]

@@MicroChemsExperiments dilution factor should be weight/final volume = 20g/10ml = 2 g/ml. not so?
