On September 8, 2010, during the "Mexexex 2010", the China Instrument and Control Society Environmental and Safety Testing Instrument Branch held the "Environmental and Safety Inspection Instrumentation Sub-Committee Conference and the Second Academic Forum on Environmental and Safety Inspection Instruments."
Concentrate Technology, as the main sponsor, participated in the event and released the first domestic portable GC-MS with complete independent intellectual property rights at the conference. The model number is Mars-400. Senior Application Engineer of Concentrating Scientific Instruments Division Civilization introduced the performance, features and applications of this instrument to the participants.
Concentrating technology is one of the domestic companies that started the research of ion trap mass spectrometry technology and realized the industrialization of mass spectrometer earlier. Through the introduction of excellent talents at home and abroad, it has established a strong R&D team. Concentrating on the support of national ministries and commissions, in the domestic scientific instrument industry and mass spectrometry field, many senior colleagues in the field of great assistance, after decades of scientific research personnel for many years of continuous efforts, successfully launched the first portable gas chromatography in China - Mass spectrometry (GC-MS) coupled with an analyzer.
As we all know, miniaturization is one of the mainstream developments of today's mass spectrometry technologies. Especially in the last 10 years, ion trap technology has developed rapidly. Because this technology can provide tandem mass spectrometry capabilities that cannot be accomplished with a single quadrupole mass analyzer, the ion trap is more suitable for quasi-deterministic analysis of unknown compounds than the latter. Concentration Technology organically combines chromatography technology with ion trap mass spectrometry to give full play to the advantages of the former in sample separation, accurate quantification and qualitative detection of the latter, and structural analysis, and is an indispensable analytical tool in the field of emergency monitoring.
This portable GC-MS can be used for emergency monitoring in many fields such as environmental pollution, disease control centers, public security criminal investigations, chemical warfare agents, security counter-terrorism, and food safety rapid inspection. Taking environmental accident emergency monitoring as an example, we mainly measure volatile/semi-volatile organic compounds in air, water, and soil/solid waste.
Instrument features:
This inspiring Mars-400 inherits the corporate mission of concentrating on “science and technology perception of the world†and its design philosophy is to create a high-quality, revolutionary portable GC/MS. This product has applied for 5 invention patents and a number of utility models, appearance patents and software copyrights from the beginning of design to the present. In the future, more original intellectual property achievements will be introduced. Compared with similar products in the industry, Mars-400 has the following advantages:
First, the portability is outstanding.
Compared with similar domestic and foreign products on the market, both shoulder-mounted and vehicle mounted GC/MS instruments, the highly integrated and modular design concept makes the size of the Mars-400 main unit a projector. It weighs only 14 kilograms and is a truly portable device that can be carried around.
Second, qualitative features are prominent.
Due to the use of ion trap technology, tandem mass spectrometry with more than 3 levels can be easily performed, so it has good qualitative ability for the more complex environmental samples of the substrate.
Third, the detection limit is low.
The patented pulsed internal ion source technology and dynamic adsorption-thermal analysis technology enable the instrument to cope with ppb and even lower trace trace sample analysis and has a dynamic range of 4 orders of magnitude or more;
Fourth, the instrument is simple to operate.
The Chinese-language software interface and touch-type human-computer interaction will give the on-site operators an unprecedented intuitive and intuitive control feeling.
Fifth, the analysis is fast.
The use of low-capacity-capacity chromatographic technology provides faster temperature/temperature reduction than a desktop oven, thus shortening the analysis cycle. In addition, under some special conditions, the instrument can work in single mass spectrometry mode, that is, the sample directly enters the mass spectrometer for analysis without going through the column separation. This is due to the fact that the ion trap technology can be used to isolate characteristic ions after selection of ion storage and multi-stage mass spectrometry functions for MS-MS analysis to obtain the "parent ion-daughter ion pair" information, thereby realizing rapid characterization.
Sixth, maintenance costs are low.
The current main consumable product of this instrument is the carrier gas of the gas chromatograph, the price is relatively cheap, because the amount used in each analysis is not big, so most domestic users can bear. Others, such as the ion source, use a dual-filament design, and the service life is double that of the monofilament. The vacuum system uses an oil-free pre-stage pump and a molecular turbo pump, so there is no operational loss in this area.
Portable GC-MS will move toward faster and lower detection limits in the future, and the next-generation product will have a qualitative leap in single analysis speed and detection sensitivity.
