The new recommended conditions are an aqueous mobile phase (mobile phase A) consisting of 5 mM or 10 mM ammonium formate with 0.1% formic acid in water and an organic mobile phase (mobile phase B) of 100% acetonitrile. Higher ammonium formate concentrations will result in reduced analyte retention. Therefore, laboratories can optimize retention by adjusting both the ammonium formate concentration and the flow rate to best meet their analytical requirements. In addition, it is recommended that labs evaluate different isocratic conditions by varying the amount of mobile phase B between 70% and 85% acetonitrile. This approach can help labs identify the most suitable separation conditions for their specific target analytes and sample matrices of interest.<\/td><\/tr><\/table><\/div><\/div><\/div><div
