can any one help me analyse bromuconazole samples with LC-MS or GC-MS, i will put him in my paper
i am pHD student from algeria and i dont have the instrmentation
LC/MS/MS instrumentation, technique is quickly gaining acceptance for pesticide residue testing. LC/MS/MS can be used to simultaneously monitor hundreds of potential contaminants—including those difficult to detect by GC. Using both LC/MS/MS and GC approaches allows for a faster, more complete picture of pesticide residues. MS/MS technology also permits identification of the target pesticides through the selection of specific MRM transitions for each compound. For example, aldicarb, a carbamate pesticide, uses two MRM transitions of 208.2->89.1amu and 208.2->116.1amu.
While the MS/MS detector allows for specific, sensitive detection of the pesticide species, the LC separation is still important to ensure the highest quality data. Conventional C18 stationary phases are typically used for pesticide monitoring, but the selectivity and retention is poor for more polar species. In contrast, Ultra Aqueous C18 columns are ideal for multi-pesticide residue monitoring methods. ,For analysis of more than two pesticides 3µm Ultra Aqueous C18 is needed. Optimized stationary phase selectivity allows for an even distribution of the compounds throughout the retention time window. As well, retention of more polar pesticides should greatly improved, . The Ultra Aqueous C18 column, in a 100 x 2.1mm, 3µm configuration is the column of choice for LC/MS/MS pesticide monitoring methods.
Ultra-high pressure LC (UHPLC) can also be used with MS/MS detection for monitoring pesticide residues. UHPLC allows for higher sample throughput when used in conjunction with a highly efficient
dear Ravi Kant Upadhyay i ask for help from someone who can analyse samples for me, your advice however is awesome, thanks a lot anyway.
well how many samples, what samples and what purpose... we are running quite a lot azoles, but not this one, but should not be too difficult to get it done. - If you want to come over there is a good research question, why not... [email protected]
