TQ 1621
BIKAI Triple Quadrupole LC-MS/MS · Models A and B
BIKAI TQ 1621 triple quadrupole LC‑MS/MS achieves femtogram‑level instrument detection limit, operating purely with nitrogen gas without requiring argon gas cylinder. Equipped with a 180° curved collision cell with axial linear acceleration, it eliminates neutral particles from ion beam and restricts MRM crosstalk down to 0.01%, preserving excellent sensitivity even for complex real‑world sample matrices.
The complete system is delivered with integrated PSA nitrogen generator and oil‑free dry fore pump with 5‑year maintenance‑free service life. It removes hassle of argon supply contract, gas cylinder management and regular oil changes. The instrument is supplied as a fully functional working system out‑of‑the‑box.
