Abstract: As one of the important components of the forum, the “Food Safety—Mass Spectrometry Analysis Technology†sub-forum was held on the afternoon of April 1, 2013. Companies such as Beijing Leibertech, AB SCIEX, and Brooke introduced the participants. The company's latest mass spectrometry technology and applications.
On April 1, 2013, the "Sixth China Beijing International Food Safety Summit Forum" hosted by the Beijing Food Society and the Beijing Food Association and undertaken by Pacific International Exhibition (Beijing) Co., Ltd. was held at the National Convention Center. This two-day summit is to discuss how to ensure the food safety of 1.3 billion people across the country from a scientific and technological perspective. The forum attracted more than 1,000 industry participants and more than 60 companies to participate. Instrument Information Network, as a cooperative media, also participated in this meeting.
Leibertech: Mobile Griffin 460 system for direct injection analysis of liquid, solid and gas samples
Beijing Leibertech introduced the Griffin 460 mobile gas-mass spectrometry system launched by the American Griffin company, which is specifically designed for on-site applications and can provide laboratory-level chemical analysis of chemicals in complex sample matrices and can be used for 24 hours Continuous monitoring of the atmosphere around the clock.
It is reported that Griffin 460 uses internal independent shock absorption technology to protect the entire system. Since all shock absorption systems are inside the system, the whole machine can be conveniently and quickly in fixed laboratory, mobile laboratory, on-site emergency laboratory, mobile testing Move between cars.
It is worth mentioning that the rich sampling accessories allow Griffin 460 to directly analyze liquid, solid and gas samples: a single system can accept direct injection of the injection needle or solid phase microextraction injection; when performing gas sample analysis , X-Shorber atmospheric sampler specially designed for on-site atmospheric sampling, can be directly connected to the Griffin 460 system through its universal interface for sample analysis; water samples can be analyzed by Griffin 460 purge and capture accessories; Or gas samples, you can also use its unique PSI-Probe sampling technology, you can achieve direct sample analysis without sample preparation, which includes TAG PSI-Probe and TWISTER PSI-Probe two technologies, for the complexity of field analysis The sample preparation process provides a revolutionary solution.
AB SCIEX: 6500 series mass spectrometer, sensitivity increased by 10 times
AB SCIEX introduced its 6500 series mass spectrometer launched in 2012. The AB SCIEX Triple Quad ™ 6500 and QTRAP® 6500 systems are next-generation mass spectrometers that have increased sensitivity by a factor of 10 compared to the best-selling high-performance triple quadrupole system currently on the market.
It is understood that the AB SCIEX 6500 series uses the new IonDrive â„¢ technology, which can ionize, transmit and detect more ions, achieving high sensitivity. The technology includes the new IonDrive Turbo V ion source, the new IonDrive â„¢ QJet import technology, and the IonDrive â„¢ HED detector with a 20-fold increase in performance. The new IonDrive Turbo V ion source makes the ionization efficiency of the sample better; and the new IonDrive QJet ion import has a two-stage design with higher ion focusing and transmission efficiency; the new IonDrive HED detector greatly improves the dynamic linearity The range can reach 6 orders of magnitude, so the sensitivity of 6500 is greatly improved.
Bruker: LC-QQQ and LC- (Q) TOF pesticide residue analysis solutions, fully meet the qualitative and quantitative needs
Bruker introduced its latest pesticide residue analysis solution using liquid-mass spectrometry technology. Including "LC-QQQ liquid quality analysis program specially designed for quantitative applications" and "LC- (Q) TOF food and drug quality control system research program".
LC-QQQ liquid quality analysis program-EVOQ series liquid chromatography mass spectrometry triple quadrupole mass spectrometry, a new mass spectrometry product introduced by Bruker in 2012, can quickly and reliably quantify thousands of actual samples, and provide Fully automatic workflow from sample management to inspection report.
The system uses an innovative interleaved quadrupole (IQ) designed dual ion funnel, which enables the analysis of small molecules and biomolecules to easily achieve ultra-high sensitivity. It has two major advantages: (1) simple, funnel-shaped design, and only RF voltage, so that the system can focus compound ions without adjusting the compound; (2) significantly reduces the instrument The number of maintenance, thereby increasing the normal use time of the instrument. Compared to the traditional stacked lens funnel design, the spatial geometry design of the IQ dual ion funnel improves the movement of background gas, thereby reducing surface contamination.
LC- (Q) TOF system research program: LC- (Q) TOF is not only used in routine analysis, but also in the analysis of unknowns, as well as in extended research such as difference comparison and metabolomics research. Compared with LC-QQQ, ESI- (Q) TOF has "the ability to speculate on unknowns; is not limited by the number of channels, and method development is simple; full data recording is convenient for risk assessment; and has a high-resolution peak shape map, suitable for similar quality Compound analysis "and other advantages. Bruker's LC- (Q) TOF pesticide residue detection scheme is based on full-sensitivity, high-resolution data, combined with professional analysis software and databases, to achieve qualitative (semi) quantitative analysis of known / unknown objects.
