New Chemical Ionization (CI) source expands range of applications
Switching between Electron Ionization (EI) source and CI source is quick and easy. When performing the qualitative and quantitative analysis of combustible samples, or for analysis where the response in EI mode is low, such as for certain pesticides, a CI source can effectively lower the limit of detection.

The newly designed ion optics system optimizes ion yields and transmission characteristics, effectively improving the sensitivity and resolution, while reducing neutral particle noise.

1 The optimized ion source filament control circuit implements constant emission and constant reception modes. In constant reception mode, the maximum change to the electron flow within a 30-minute period is 0.02 μA. Due to the enhanced performance of the feedback system, the stability of the ion signal has been improved. The new, innovative voltage offset technology optimizes the spatial distribution of the electron beam which increases the signal to noise ratio by 30%.

2 The improved ion source optical system uses a redesigned magnetic field to more accurately focus the ion beam, which reduces the adverse effects of excessive magnetic fields on the ion trajectory of back-end ion optics system, and improves the ion transmission, and thereby enhances the mass resolution and signal to noise ratio.

3 The vertical focus detector system utilizes a high-gain, low dark current electronic multiplier and polished mirror parabolic dynode to decrease neutral noise and background interference of filament photons and to increase high mass end response.

Improved quadrupole circuit control system achieves equal peak width identification within the full mass range and optimizes conduction rates.

1 The sampling system utilizes the most advanced FPGA processing technology. Sampling frequency has been increased to 1 MHz. More data points are processed. Signal stability has been improved. Digital I/O communicates with the workstation using high-speed USB allowing fast data transmission. DC dynamic compensation technique significantly improves the relative transmission rate of target ions. M/Z 502 has been increased from 6.4% to 37.6%.

2 Improved preamplifier circuit utilizes shorter analog signal transmission lines, and enhanced shielding against electromagnetic interference. Electrostatic noise has been reduced by one-third, and linear dynamic range has been increased to 105 with linearity in the range of 10-12g to 10-7g.

3 Improved data communication interface can complete a connection with the workstation within 30 seconds.

4 More rigorous fault alarm functions were added for protection of pump power, axis temperature, and each subcomponent's temperature and high-voltage output. Even a new user will not need to worry about damage to the instrument caused by operation error. Advanced warning function will alert the user to potential issues that may cause significant damage or loss of supplies to help users reduce cost and improve efficiency.

High-Performance, High- Spec Vacuum System
1 Vacuum system utilizes a 250 L/s turbo pump and a 10 m³/min two-stage rotary vane mechanical pump and can be used with large diameter capillary columns to enhance analysis speed and sensitivity. The whole vacuum system combines noise isolation technology with an intelligent noise reduction box to provide a clean high vacuum and a quiet laboratory environment at the same time.

2 Wide range cold cathode vacuum gauge allows vacuum measurement from atmospheric pressure to 10-7 Pa and features long usage life, no consumables, no special maintenance and low cost.

Gas Chromatograph and Sample Introduction Unit
1 New industrial design is simple and elegant, with a distinctive, user-friendly GC control panel. Interface was designed with protection from user error in mind.

2 Innovative rotatable liquid autosampler can rotate 360° on the horizontal plane. The autosampler can be easily removed from the mount to simplify the GC maintenance.
