many researchers have analyzed pesticide residue in soil by using GC/MS or GC-ECD. But my lab has GC-FID. can I get the result by using GC-FID?
Hi,
Yes, you can measure by gas chromatography (GC) as well as high-performance liquid chromatography (HPLC) and other types of chromatography.
No. You will need an MS detector to gain an additional dimension of analysis. Retention time alone is not enough for pesticide ID. Either GC-MS and/or LC-MS (or better yet, LC-MS/MS) are needed for basic quant and ID. Using just GC-FID alone may provide only a limited amount of information (qualitative) so even when used with proper standards may or may not be enough for your application.
Please define your exact goals and objectives, then research your question online using a keyword search for examples.
Agree with William,
If you want to achieve lower detection sensitivity then you have to go with GCMS and GC-ECD.
Hi Prasanta Majee ,
depend on your research e.g. well know and high level of residues etc; however, in general you should use the methods recommended in this link https://www.eurl-pesticides.eu/docs/public/home.asp?LabID=100&Lang=EN or other similar.
For achievement of high level qualitative and quantitative precision in the course of analysis, levels of pesticide residues are perfectly established using GC-MS or LC-MS. So the choice of analysis and the expected result will also depend on the scope of work or analytical design and the instrumentation involved.
Yes, you can analyze with GC-FID some of the technical grade pesticides like, Thiamethoxyzome, Cypermetrins, Pyrethrins and some other pesticides and try with ECD and you can analyze the organochlorine pesticides. Based on the sample nature and selection of detector.
Yes you can do it but for a wide spectrum elucidation and quantification of samples, l suggest you make use of GC-MS or LC-MS
