WebThe post-column derivatization method involves separating the amino acids in the column, then delivering and mixing the derivatizing reagent to let it react with the amino acids, before finally sending the products to … WebThis study demonstrates that with the proper use of derivatization reagents such as MTBSTFA, amino acids can be analyzed by GC-MS. The reaction conditions may have to be “tweaked” to produce maximum response of the derivatives of interest. The derivatives produce characteristic fragments, allowing for easy identification by MS. huawei mediapad t3 kob-l09 firmware download
