Product Features

Mass spectrometer

The mass spectrometer has both electronic and chemical ionization sources

Electronic ionization source (EI) and chemical ionization source (PCI) can be quickly switched, effectively reducing the detection value of extremely low quantitative analysis, pesticide detection, qualitative and quantitative analysis of explosives

High precision ion optical system

The ionization source is controlled by a highly stable current source. Within 30 minutes of measurement, the maximum error of the electron flow is only 0.02uA. In addition, there is a voltage compensation design, which makes the optical system of this product have a good signal-to-noise ratio, sensitivity and resolution.

High precision quadrupole analyzer and vertical focusing detector

EWAI has mastered the production technology of high-precision base components and added innovative patented design inventions. For example, the special patented invention used by the quadrupole can provide good resolution, transmission rate and frequency response. The vertical focus detector system and parabolic electron multiplier use advanced mirror polishing technology (thanks to the local rapid mobile phone precision processing technology) to significantly reduce the background interference of neutral noise and filament photons, thus providing a high level of hardness. In addition, these two key components have been completely self-produced and self-made, so users do not have to worry about the instrument becoming orphaned due to parts being discontinued.

High speed digital sampling circuit and advanced analog circuit design

The digital circuit of GC-MS-3200 adopts an FPGA with a frequency of 100MHz to ensure high-speed sampling frequency and maintain the relative transmission rate of target ions at high speed. In addition, in the design of the analog circuit, special emphasis is placed on the design of the preamplifier, so that the linear dynamic range of the GC-MS-3200 can reach 10 ^ 5, which is why the measurement range of the GC-MS-3200, from 10 ^ - 12g to 10 ^ - 7g, can maintain good linearity.

Fault warning and foolproof mechanism

The research and development unit of EWAI has also put a lot of effort into the security control of GC-MS-3200. For real-time monitoring, warning, and intelligent protection of vacuum pumps, shaft temperature (and other parts of the temperature), and high-pressure output, even if using GC-MS-3200 for the first time, there is no need to worry about instrument damage caused by misoperation. EWAI's engineering team ensures the maximum protection of your safety and the safety of the instrument.

High specification turbo molecular pump

The GC-MS-3200 has the highest vacuum silent molecular pump configuration among GC-MS of the same grade, with 10m ^ 3/min twin turbine blades, capable of reaching a extraction speed of 250L/s. And due to excellent noise isolation technology, the pump is still very quiet under efficient operation. In addition, this turbo molecular pump is equipped with a cold cathode vacuum gauge measuring from atmospheric pressure to 10 ^ -7 Pa, making it very durable and long-lasting, with almost no replacement issues.

Tomograph

EPC has diverse intake control modes

The intelligent controlled blowing and trapping device can choose modes of constant temperature, constant pressure, split flow, and no split flow. Moreover, due to its unique instantaneous switching valve design, compared to other similar instruments, it can stabilize pressure faster and effectively improve spectral peak and reproducibility in the non split flow injection mode.

Precision GC Temperature Control System

The temperature control of the column box reaches ± 0.03 ℃, greatly improving reproducibility. Programmable temperature control can improve the reproducibility of oil detection and obtain sharper chromatographic peaks. The preset gas path design for nitrogen, hydrogen, and air allows users to install other chromatographic detectors according to their needs.

Unique CI reaction airflow control module

The reaction gas flow rate can be automatically adjusted based on the preset ratio of target ions in CI gas, and the optimal flow rate value can be maintained. In addition to saving reaction gas, it can also ensure the reproducibility of CI analysis.

Design a simple and practical liquid and solid sampler

It can quickly obtain structural information of unknown objects, and a detachable heating probe with a temperature of up to 650 ℃ can replace itself when the probe is damaged or contaminated, saving costs. GC-MS-3200 is the most powerful and reliable instrument in the chemical plant.

Powerful free software MS3200RT

GC-MS-3200 provides powerful software with fully functional measurement and control functions. The most intuitive operation interface, based on your experience in operating other instruments, allows you to quickly get started. The chromatography, mass spectrometry, tube parameters, and instrument status are displayed simultaneously, allowing you to capture every dynamic information during the analysis process at any time.
