The portable gas chromatography mass spectrometer (GC-MS) is an analyzer based on low heat capacity chromatography combined with miniaturized quadrupole mass spectrometry. The analyzer adopts an inert election bombardment ion source, a miniaturized quadrupole mass analyzer, which has a fast warming thermal desorption, and low heat capacity gas chromatography. It can be stalled in a mobile monitoring vehicle or carried on the shoulder to the site for testing. It can be used for fast qualitative and quantitative analysis of volatile organic chemical pollutants (VOCs) and semi volatile organic chemical pollutants (SVOCs) in tha atmosphere, water and soil. It is also a powerful analytical tool in the fields of environmental monitoring, fire fighting and emergency response, occupational health and public safety.

The general-purpose gas chromatography-mass spectrometry (GCMS) adopts an inert ion source, all-metal molybdenum  pre-quadrupole and main quadrupole, and a high sensitivity detector design. It is capable of qualitative and quantitative detection of complex organic compounds. It can be widely used in food and pharmaceutical monitoring, environmental monitoring, chemical industry, petroleum and other fields.

The general purpose gas chromatograph (GC) is configured the high-precision flow control modules, different detection units according to the measuring components and applications, injection units. Different inlet ports will be installed based on the types of column, either split/splitless injection unit (SPL) or single packed injection unit (SINJ). The cooling time of the column oven from 450 degrees Centigrate to 50 degrees Centigrate is as low as 4 min. It is widely used in food and pharmaceutical monitoring, environmental monitoring, chemical industry, petroleum and other fields.

Based on the Doppler effect, the ZDMFA-01 Ultrasonic Doppler Flow Meter can simultaneously monitor the flow rate, velocity, water level, water temperature and other parameters with millimeter-level accuracy, suitable for fluid flow measurement in a variety of environments. In a one-package structure, the product is easy to operate, waterproof and pressure resistant, not affected by external environments and has a low failure rate. Therefore, the product meets the user`s requirements for high accuracy and high stability.

Portable VOCs analyzer is based on FID and PID technology, which can achieve ultra-high sensitivity and fast detection and analysis of VOC gases in ambient air. The analyzer adopts intrinsically safe and explosion-proof design, consisting of two parts: main unit and sampling rod, equipped with explosion-proof hand manipulator. It is mainly used in unorganized on-site emergency detection, rapid detection of emissions from stationary source, energy efficiency assessment of VOCs treatment facilities, VOCs traceability investigation, pipeline emission and leakage detection, onsite investigation of gas station and oil depot oil recovery, etc.

The DC-200 Dynamic Diluter uses high-precision mass flow controllers (MFC) to accurately controls the flows of dilution gas and standard gas so as to get standard gas of required concentrations. The standard gas path is made of passivated stainless steel tubes and is heated throughout to reduce the impact of sample residues on dilution accuracy. The product is mainly used in plant boundaries, ambient air on-line monitoring systems and preparation of standard gas in laboratories, with the advantages of high accuracy of gas proportioning, fast response time, high reliability and easy operation.

The Explosion-Proof FID Detector consists of an explosion-proof cavity, mounting base of flame arrester element, signal transmission line, control wire of temperature transmission and ignition heating wires, etc. When the organic gas is fed into the FID detector, the chemical bonds of the organic gas are opened under the action of high temperature ionization, releasing free ions and electrons. The released electrons move toward the electrode at one end of the high-voltage electric field, and thus are collected by the electrode to produce a measurement current. The magnitude of this measured current is related to the mass of organic gas entering the detector per unit time, and the total amount of signal collected during the injection time reflects the content of the organic gas.

The Enrichment Desorber is a pretreatment device for gas chromatography analyzers. It is a fully automated, direct-feed, single-channel cold trap enrichment and thermal desorber that uses a combination of six-way valves and solenoid valves in the gas line design, and Tenax or activated charcoal adsorbent tubes as the enrichment and thermal desorption tubes to enrich trace volatile organic compounds (VOCs) in the ambient air, thus lowering detection limits of chromatography analyzers.
