LC-Triple Quadrupole MS/MS System

液相色谱三重四极杆串联质谱仪（LC-MS/MS）

Bioanalysis, clinical assays, PFAS and residue testing all depend on triple quadrupole sensitivity and speed. This LC-MS/MS scans up to 20000 Da/s, dwells for 1–2 ms per MRM, switches polarity within 20 ms and reaches S/N of at least 10000:1 for 1 pg reserpine. Linear range is 10^5 or more. Tell us your assay panels.

Mass range: m/z 5–2000
Scan speed: up to 20000 Da/s
Minimum MRM dwell time: 1–2 ms
Polarity switching time: ≤ 20 ms
Sensitivity (reserpine, 1 pg on column, ESI+ MRM 609>195): S/N ≥ 10000:1 (typical, RMS)
