The required analysis can be done in our laboratories but we shall require first the details of your requirements. You can send the details to me on my e-mail id deepak.bhanot@aurigaresearch.com and provide me your complete mailing address and contact information. Regards

In reply to Mr Uche uzoagba. Aromatic halogenated compounds can be analysed using a gas chromatograph with electron capture detector.For plant extracts please specify some compound classes

please Dr Deepak, what chromatographic technique is ideal for quantitative and qualitative analysis of aromatic halogenated compounds and what technique is also most suitable for determination of components of plant extracts that are required for antimicrobial sensitivity test.

nice about hplc and Gc
plz discuse the working bases of detectors and X-rays spectroscopy

In reply to Dr Amina Rashad. Hi Dr Amina, Volatile oils and other similar compounds are generally detected by GC using Flame Ionization detector which is a destructive detector which in any case burns up and destroys the injected compounds.However, the more volatile the sample the earlier it will reach the detector after separation in the column and it ts peak response will be seen before the other less volatile specimen components.

thank you dr. Deepak. A very rich topics. But I wondered does the high temperature of GC detector could affect the injected compounds especially volatile oils specimens.

Dear Dr. Bhanot,
I greatly appreciate your efforts in enlightening us with the nuances of analytical chemistry. Your articles give us a paradigm shift and focus in understanding the subject whether it may be theory and/or instrumentation.
Thank you,
Hari, N.
