● Triple quadrupole mass spectrometer
. Ion source
1.The ion source ensures the maximum number of ions ionized and the minimization of noise producing neutral particles and energetic ion clusters.
2.The spray atomizer is axially perpendicular to the well plate interface to improve the spray effect and greatly reduce neutral particles entering the mass spectrometer, thus eliminating noise.
3.By providing an electrospray ion source (ESI) and an atmospheric pressure chemical ionization source (APCI), substances of different polarities can be analyzed.

* Ion guidance:High frequency (RF) dual ion funnel optically optimized for large range ion transport while performing efficient ion focusing.

* Quadrupole used with pre and post filters 1 and 2 to optimize ion transport and spectral level resolution.

* Collision unit: Collision unit with optimized mode for high voltage 180 degree bending while eliminating interference.

* Detector: Electron gas pedal with 5 kV back acceleration.

* Vacuum system: Two single-stage 40L/h primary pumps and three-stage 25/300/400L/s turbomolecular pumps.
