AMP+ MaxSpec® Kit
别名:
GELB Derivitization Kit
产品描述:
Many lipids have a free carboxylic acid group that typically requires a weak acid mobiles phase to ensure retention by HPLC. Unfortunately, the presence of the acid in the mobiles phase also suppresses anion formation and often leads to poor electrospray ionization and poor MS sensitivity. Cayman’s AMP+ MaxSpec® Kit contains a positively charged reagent (AMP+) that can be coupled quantitatively to free carboxylic acids through an amide bond linkage. The resulting derivatized product thus contains a positively charged group that shows improved electrospray ionization and consequently improved MS sensitivity. Cayman’s derivatization reagent is stable to MS/MS fragmentation and thus isobaric derivatives undergo compound-specific fragmentation to give unique fragment ions. Limitations: This kit, when used per the instructions outlined in the booklet, produces derivatized stearic acid and palmitic acid interference peaks. Due to these interferences, this kit should not be used for the detection or identification of these two acids in samples.{60074,60075}
