Where background matters
PFAS, nitrosamine and other ultra-trace methods are limited by consumable background — not by the instrument. ALWSCI's ultra-clean line (the first and only in China for LC/MS, GC/MS and EPA consumables, per company statement) targets particles and organic residues on vial interiors.
