Recently we met a severe problem while using agilent 6470 LC-QQQ. We want to determine the concentration of PFOS, using MRM mode, with the precursor of 499 m/z and product of 99m/z. The mobile phases are methanol and 5mM ammonium acetate in 10% methanol.   The problem is: after one month of testing when I injected blank samples (MS grade

The model number on GC is 6890N (G 1540N). I am using a method with split injection with 50:1 split ratio on hp-5 column to measure concentration of a methanol/water mixture using ipa as an internal standard. The method has been successfully used giving a reasonable standard deviation for several months, and recently the standard deviation
