Mass range: at least 6amu, the maximum mass is not less than 2980 amu

Resolution(full mass range): unit mass resolution (full scan)

MRM sensitivity:

electrospray ionization ESI: positive ion 1 pg, Reserpine direct injection, MRM analysis609/195, signal to noise ratio > 2500:1 (RMS)

Negative ion 1pg chloramphenicol direct injection, MRM analysis 312/152, signal to noiseratio S/N>1400:1

APCI:1pg Reserpine direct injection, MRM analysis measurement 609/195, signal tonoise ratio >500:1 (peak to peak ratio)

Detection limit of mass spectrometry: Clenbuter detection limit ≤0.01ppb; chloramphenicol detection limit ≤0.01ppb

Scanning speed: maximum >2300 amu/sec

Dynamic linear range of data acquisition: >4*10⁶

Linear Accelerated High Pressure Collision Chamber Design: Pressure greater than 7mtor, improves ion transmission efficiency, improves sensitivity, eliminates memory effects and cross-contamination

Quantitative analysis reproducibility:

low concentration: chloramphenicol 0.1 ppb, injection volume 20 μl, N=5, CV <3%;

High concentration: chloramphenicol 2ppb, injection volume 20μl, N=5, CV<3%;

5ppb;50ppb glycerol and cholesterol were injected 5 times respectively RSD<1%

One injection, regardless of time window: 300 compound MRM quantification andlibrary search simultaneously complete no loss of sensitivity, with actualspectral support.
