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

[@MicroChemsExperiments]

Glad it was helpful!

[@virtualtour7159]

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

[@kabitawangjam3742]

Thanks for uploading this video's...this is very helpful

[@KenwasiFFYT]

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

[@MicroChemsExperiments]

Welcome. Stay with us.

[@MerazulMomenin-i4o]

Superb. You made easy to determine the pesticide residue.

[@MicroChemsExperiments]

Stay with us

[@MerazulMomenin-w1w]

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

[@MicroChemsExperiments]

Glad you enjoyed it!

[@MerazulMomenin-n2e]

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

[@MicroChemsExperiments]

Thanks a ton

[@JagbinderKumar]

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

[@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

[@MerazulMomenin]

Nice Video. Very Helpful

[@MicroChemsExperiments]

Glad it was helpful!

[@KenwasiFF]

Thanks for this. Soo needed video

[@MicroChemsExperiments]

You are welcome.

Sir yis video ka koi references pdf milega plz...

[@UsmanAli-pb2lk]

Please why did you use the cotton wool method and not SPE cartridges, does it mean i can replace the catridge with this method,,,,i am carrying out research on analysis of organochlorine pesticides residues...please reply thabk you

[@madhusmita1131]

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

[@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?

[@mst.anikaakter4061]

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

[@MicroChemsExperiments]

Yes. You can

[@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.

[@md.marazulmomenin2644]

Nice Experiment.

[@MicroChemsExperiments]

Thank you! Cheers!

[@nashwarasheeda]

thank you! is this also aplicable for meat analysis?

[@MicroChemsExperiments]

Yes

[@MasudRana-jc5qj]

Thankyou respected ❤❤

[@MicroChemsExperiments]

Thanks a bunch

[@merzulmomenin3038]

Can I use Petrolium ether instead of hexane? Thanks

[@MicroChemsExperiments]

Hexane is betted but you can use Petroleum Ether

[@harshitagupta1650]

Which extraction method you have used sir

[@sisayshediso]

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

[@MicroChemsExperiments]

Yes. QuEChERS method is different

[@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

[@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-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

[@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?

[@maltisainimedico]

Can We detect pesticide by TLC

[@MicroChemsExperiments]

No

[@bhaveshsingh9132]

I am also interested in this field.

[@MicroChemsExperiments]
