Hi,

I am looking for an application on Methylmalonic Acid (MMA) in urine and serum

Thanks

We have a column for analysis of acidic and neutral compounds in biological fluids (serum urine, etc.). It alows you to inject smaples directly into the column. Mobile phase is LC/MS compatible (formic acid, ammonium acetate, ammonium formate at pH=3-4)
