LC-MS Compatible HPLC Method for Tramadol
Tramadol can be retained by Reversed Phase HPLC but some reported methods require Phosphate buffer additives in the Mobile Phase, which means incompatibility with LC-MS. In contrast, this Method uses Formic Acid as the Mobile Phase additive.
An advantage this method has is that it produces enhanced signal-to-noise compared to Reversed Phase thereby producing better results. High Water content in the Reversed Phase Mobile Phase is often required for retention.

Since Water is less volatile than Acetonitrile, it is more difficult to remove in LC-MS, hence also leading to lower sensitivity than this Method.
