The front stage vacuum pump adopts GLD-N201 small direct coupled oil rotary plate vacuum pump with a geometric pumping speed of 4L/s.

Two specifications of small turbo molecular pumps, providing * * performance to meet your needs and budget.

TMH071P magnetic levitation small turbo molecular pump, geometric pumping speed of 60L/S (standard configuration).

TMH262P magnetic levitation small turbo molecular pump, with a geometric pumping speed of 210L/S (optional).

Cold cathode ionization vacuum gauge, detection range 1.0 × 10-5~1 × 102 Pa

ion source

An independently heated EI electron bombardment source with a maximum temperature of 350 ℃.

The maximum filament emission current is 200 μ A.

The electronic energy is adjustable from 10-100eV and has low voltage operation function.

The overall plug-in design allows for easy maintenance of the ion source without the need for complex operations.

quadrupole mass filter

The high-precision metal quadrupole mass analyzer ensures the achievement of standard unit mass resolution.

Detachable pre quadrupole filtering device reduces contamination of the main quadrupole and avoids cleaning and maintenance of the quadrupole.

The pre quadrupole filtering device is equipped with a voltage that varies with the scanning quality, which can improve the edge field, increase the ion incidence efficiency, and achieve better detection sensitivity.

detector

High voltage conversion nanograde electron multiplier.

The small signal amplifier of composite I/V conversion circuit technology effectively reduces circuit noise, improves signal-to-noise ratio, and ensures excellent linear dynamic range.

electronic system

High quality RF power supply can achieve full quality range quality axis calibration with just two points, maintaining good linearity in full scan mode.

Excellent electromagnetic compatibility design and high-precision, low-temperature drift electronic components ensure excellent quality accuracy and stability of the instrument.

32-bit embedded control system, using 100Mbps Ethernet communication interface, can achieve remote control and networked sharing.

A highly modular power system and control circuit system enhance the overall reliability of the instrument, facilitating maintenance and upgrades.

software system

The Chinese software system is divided into four functional modules: instrument control, data acquisition, data processing, and spectrum retrieval (NIST08). Intuitive and intelligent, easy to operate.
