Instrument usage

The portable GC-MS analyzer is easy to carry and can be brought to the accident site at any time for quick start-up and testing. It can also be used for rapid testing of laboratory samples. Due to its programmed temperature range of 40 ℃ to 300 ℃ and mass number detection range of 45 to 500 amu, the sample detection range is relatively wide, making it very useful in both accident sites and laboratories. Main applications: rapid qualitative and quantitative detection on site and in laboratories, identification of toxic industrial compounds, biochemical weapon preparations, environmental pollutants, flammable and explosive oil products, explosives, etc.

TRIDION-9Performance Overview

1. TRIDION-9Portability

The TRIDION-9 portable GC/MS, including the standard battery, weighs only 14.5kg and has a size specification of 38cm * 39cm * 23cm, making it very easy to carry. With just one hand, you can bring our portable GC/MS to any testing site. Among them, our instrument has stable performance and can adapt to various extreme and harsh environments, far exceeding the written indicator data in practical applications.

2. The startup time is less than5min

Traditional desktop GC/MS often takes more than 4 hours from start-up to instrument stabilization, and then to start sample detection. In other existing portable GC/MS, the start-up time is greatly shortened, but it still takes more than 30 minutes. However, TRIDION-9 portable GC/MS takes about 4 minutes from power on to sample injection, fully reflecting the fast advantages of portable GC/MS

3. Sample collection and injection methods

The TRIDION-9 portable gas chromatography-mass spectrometer mainly has three injection methods: solid phase microextraction (SPME), needle trap, and direct liquid injection.

Solid phase microextraction sample enrichment and injection method

Suitable for rapid qualitative enrichment injection of volatile organic compounds in gases, liquids, and solids, and for enrichment injection of semi volatile organic compounds in liquids and solids

Dynamic volatile organic compound qualitative and quantitative enrichment and injection device

Suitable for rapid qualitative and quantitative enrichment injection of volatile organic compounds in gases, liquids, and solids

Direct liquid injection method

Suitable for direct qualitative and quantitative injection detection of semi volatile organic compounds in liquid samples (without any pre-treatment method, can be directly applied to water samples)

4. Rapid sample testing data

Our portable GC/MS gas chromatography module uses MXT-5, a 5m × 0.1mm × 0.4 μ m df low thermal capillary chromatography column, which is an efficient separation column. Our gas phase module adopts a programmed heating mode, with a heating range of 40 ℃ to 300 ℃ and a maximum heating rate of 150 ℃/min. The detection time for each sample is usually only about 3 minutes, and the peak width of each separated chromatographic peak is approximately 1-2 sec. In the detection of volatile and semi volatile organic compounds, about 50 chromatographic peaks can be separated within 3 minutes.

5. The mass spectrometer adopts a patented circular ion trap technology

Due to the easy miniaturization of ion traps and their lower operating vacuum compared to quadrupole rods, portable GC/MS chooses ion traps as mass analyzers with higher stability and sensitivity than quadrupole rods. TRIDION-9 portable GC/MS has chosen a patented circular ion trap as its mass analyzer. Its quality testing range is 45-500amu, and it can be well applied in the detection of environmental pollutants, pesticides, toxins, and drugs.

For circular ion traps, they have the following advantages compared to common ion traps:

All ions undergo the same capture and mass spectrometry analysis process

L is easier to adapt to ionization and detection light paths

Compact structure (compared to linear ion traps with the same storage capacity)

The electromagnetic field is a uniform field (compared to a linear ion trap)

There is no end effect, and all spatial field effects in the analyzer are equal

In addition, our ion source uses a 70eV EI source, and the mass spectrometry characteristic peaks generated can not only be compared with our self built spectral library, but also with the NIST spectral library. The vacuum system adopts molecular turbo pumps and mechanical diaphragm pumps, and its vacuum system configuration is not limited by its service life.

Our portable temperament is used in the work of the environmental monitoring department

The environmental monitoring department purchased our portable air conditioner mainly for monitoring small molecule organic pollutants in air, water, and soil;

2. In terms of water quality monitoring, it is mainly based on the testing items in the 106 items of water quality monitoring stipulated by the state.

Among them, 34 phases need to be tested using our portable gas analyzer, while other testing items require liquid phase, UV spectrophotometer, turbidity meter, COD and other instruments for testing. This is not related to our portable gas analyzer, so you don't need to pay attention, just focus on the 34 testing contents we can do.
