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 TH-cam. These videos are very helpful for laboratory analysts.

[@MicroChemsExperiments]

It's my pleasure

[@user-mv5ym6ok1v]

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

[@MicroChemsExperiments]

Glad it was helpful!

[@lightangle4428]

Great video. TH-cam does not have this kinds of video except yours. Thanks for making this.❤❤❤

[@MicroChemsExperiments]

Welcome. Stay with us.

[@user-pm4qi6yl1m]

This is the most wanted experiment. Just loved it. Keep going Sir. Salute

[@MicroChemsExperiments]

Thanks a ton

[@user-gw1vu7lr8u]

Very organized and well equipped video. Thanks for uploading this.

[@MicroChemsExperiments]

Glad you enjoyed it!

[@user-sb8ql3jz6d]

Superb. You made easy to determine the pesticide residue.

[@MicroChemsExperiments]

Stay with us

[@user-lq8vs6pq1p]

Nice Video. Very Helpful

[@MicroChemsExperiments]

Glad it was helpful!

[@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?

[@soon_to_be_knowYT]

Thanks for this. Soo needed video

[@MicroChemsExperiments]

You are welcome.

[@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.

[@user-jf6rr8sy6c]

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

[@MasudRana-jc5qj]

Thankyou respected ❤❤

[@MicroChemsExperiments]

Thanks a bunch

[@rimadessai7976]

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

[@sisayshediso]

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

[@MicroChemsExperiments]

Yes. QuEChERS method is different

[@md.marazulmomenin2644]

Nice Experiment.

[@MicroChemsExperiments]

Thank you! Cheers!

[@mst.anikaakter4061]

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

[@MicroChemsExperiments]

Yes. You can

[@mysoulis5267]

Thank you

[@MicroChemsExperiments]

You are welcome

[@user-hf7wp1dh1y]

Thanks

[@MicroChemsExperiments]

No problem

[@harshitagupta1650]

Which extraction method you have used sir

[@mohdabrar2839]

thanks

[@MicroChemsExperiments]

You are welcome

[@merzulmomenin3038]

Can I use Petrolium ether instead of hexane? Thanks

[@MicroChemsExperiments]

Hexane is betted but you can use Petroleum Ether

[@bhaveshsingh9132]

I am also interested in this field.

[@MicroChemsExperiments]

Good

[@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

[@anumjaved3702]

Testing of antibiotics residues in food samples of animal origin?

[@MicroChemsExperiments]

Already uploaded

[@zainabveterinary4055]

Hi can we use this procedure for extraction of ivermectin ? Please answer me 🥺

[@MicroChemsExperiments]

No. You can't use this method for ivermectin

[@zainabveterinary4055]

How can I extract ivermectin? please

[@klipjiang4422]

Why dilution factor is 2? Thanks

[@MicroChemsExperiments]

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

[@maltisainimedico]

Can We detect pesticide by TLC

[@MicroChemsExperiments]

No

[@maltisainimedico]

@@MicroChemsExperiments how are you so sure

[@priyasingh-zc1hb]

ma'am what is a name of this method

[@MicroChemsExperiments]

Florisil cleanup and extraction method

[@priyasingh-zc1hb]

thank you ma'am@@MicroChemsExperiments

[@bhaveshsingh9132]

Can you give me chance

[@MicroChemsExperiments]

Not in my lab. Try to join in other labs

[@sanjeetshah3990]

🤯 I not understand anything again 🤯

[@helalhossain5612]

why didn't you mention GC in first place, thats cheating.
