THE PROCESS
SEPARATE → FILTER → QUANTSTEP 01
UHPLC SEPARATION
The 1260 Infinity II binary pump drives C18 reversed-phase gradients up to 1,200 bar — compounds resolved by retention time before the MS ever sees them.
STEP 02
ELECTROSPRAY IONIZATION
The ESI source nebulizes eluent under heated N₂ flow — molecules are charged intact, positive and negative modes.
STEP 03
TRIPLE-QUAD MRM
Q1 selects the parent ion → the q2 collision cell fragments it → Q3 passes a signature daughter ion. Two transitions per analyte — near-zero false positives.
STEP 04
QUANT & REPORT
Peak areas ratio against certified reference standards and isotope-labelled internals — the number is generated, validated and reported.
