Thermo GC-MS System ITQ1100 Brief Introduction
The ThermoScientific ITQ1100 Gas Chromatography Mass Spectrometry (GC-MS) system is part of the ITQ series of GC/MS instruments. Whether in research or everyday applications, it can significantly utilize the capabilities of GC/MS. With its expanded mass range, comprehensive list of standards, and the performance and versatility of ThermoScientific gas chromatographs, the ITQ1100 GC-MS instrument has become a powerful tool.

Thermo ITQ1100 Gas Chromatography-Mass Spectrometry (GC-MS) Instrument Detailed Information
The ThermoScientific ITQ1100 Gas Chromatography-Mass Spectrometry (GC-MS) system boasts unparalleled scan sensitivity, an extended mass range, and standard MSn (MS/MS, n=5) mode, making it an ideal choice for research institutions, food safety analysis, environmental, and toxicology testing applications. Moreover, the ITQ1100's new MSn scanning feature provides richer data, which aids in easier structural analysis and confirmation.

Thermo GC-MS System ITQ1100 Features
1. Suitable for routine detection of compounds that cannot be detected by other GC/MS technologies, even matrix techniques.
2. During a single data collection, both primary and multiple mass spectrometry information can be obtained simultaneously.
3. Restore your ITQ1100 instrument in minutes without deflation. Simply use a standard vacuum probe chain device to easily alter the ion size.
4. New scanning features for multi-stage mass spectrometry experiments: The ITQ1100 comes standard with two scanning functions, both of which are first applied in the ITQ series—Automatic Collision Energy (ACE) and Pulsed Q Dissociation Mode. With these features, the advantages of MSn can be easily exploited, optimizing methods become simpler, and data quality is enhanced.
5. External Ion Source: The ITQ1100 maintains a stable state unaffected by temperature from 125°C to 300°C, enhancing chromatographic performance. When ionization occurs outside the ion trap, the integrity of the spectrum is improved, and the system can remain cleaner for a longer duration, thereby extending the operational time of the system.
6. Data-Dependent Scanning: Data-dependent scanning enables us to record MS/MS information without prior knowledge of specific parent ions. This type of scanning is beneficial for multi-stage mass spectrometry experiments. Both the full-scan primary mass spectra suitable for library searching and the multi-stage mass spectra related to structural information are simultaneously recorded and utilized.
7. Excellent availability and versatility.

Introduction

In 2014, the EU's relevant agencies introduced a new proposal to add hexabromocyclododecane (HBCDD), bis(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), and benzyl butyl phthalate (BBP) to the RoHS 2.0 directive for priority assessment. This will present a significant challenge for electronic and electrical product manufacturers. The HBCDD, DEHP, DBP, and BBP in electronic and electrical products, as well as the polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) specified in the previous RoHS 2.0 directive, are all detected using gas chromatography-mass spectrometry (GC-MS) as the standard method. The GC-MS 6800, a cost-effective GC-MS meticulously crafted by Tianrui Instruments, boasts multiple patented technologies, offering efficient and rapid analysis with accurate qualitative and quantitative results, and easy software operation. The instrument is easy to maintain and clean, suitable for long-term and stable use by both corporate and laboratory users.

Appendix 3: Interlaboratory Comparison Certificate (Decabromodiphenyl ether)
"A Gas Chromatography-Mass Spectrometry (GC-MS) system is an integrated system that combines a mass spectrometer with gas chromatography. Gas chromatography is a separation and analytical tool for multi-component substances, utilizing a column chromatographic technique with gas as the mobile phase to perform qualitative analysis of the substances being tested. A mass spectrometer is a device that measures the mass-to-charge ratio (charge-mass ratio) of ions to obtain the mass spectrum of the analyzed sample, thereby completing its mass measurement. Currently, the usage rate of similar equipment on campus is high, and the machine hours are fully utilized. The expert group, based on the research needs of the applicant's team, believes that the key to the prevention and control of semi-volatile organic compounds (SVOCs) and persistent pollutants is the determination of trace SVOCs at the ppb level. The equipment to be purchased is a powerful tool for accurately quantifying these trace organic substances. The acquisition of this instrument will promote the development of the university's Water and Sediment Science and Environmental Engineering."
The expert group unanimously agreed to pass the feasibility argument for the aforementioned equipment. The funding source for the equipment acquisition is the "Overall Support Fund for University and Discipline Construction," applied for by Academician Juren Ni from the School of Environment. The funding for the acquisition of the equipment has been secured, and operating funds are guaranteed. The equipment will be used to serve in-house research after purchase, with an estimated annual open and shared machine hours of around 400.

GC-MS Experiment Objective
Understand the basic composition and working principle of mass spectrometers, and learn the tuning methods for mass spectrometers.
2. Familiarize yourself with the basic functions of a chromatography work station and master the basic operations for qualitative analysis using a gas chromatography-mass spectrometry (GC-MS) system.
Gas Chromatography-Mass Spectrometry (GC-MS) Experimental Principle
Gas chromatography (GC) is a widely used separation technique, which is a column chromatography using an inert gas as the mobile phase. Its separation principle is based on the differences in the distribution of components between the two phases. While GC can separate the various components within a complex mixture, its qualitative ability is poor, typically relying on the retention characteristics of the components for qualitative analysis. This can be challenging when the components to be identified are completely unknown or when standard samples of the components are not available. With the development of techniques such as mass spectrometry (MS), infrared spectroscopy, and nuclear magnetic resonance for qualitative analysis, online hyphenation technologies are now primarily used, directly connecting chromatography with other qualitative or structural analysis methods to address the challenges of chromatographic qualitative analysis. Gas chromatography-mass spectrometry (GC-MS) was one of the earliest chromatography hyphenation instruments to be commercialized. Currently, compact desktop GC-MS systems have become a standard configuration in many laboratories.

RoHS is a mandatory standard established by the European Union legislation, officially titled "The Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" (Restriction of Hazardous Substances). It was enforced as of July 1, 2006, primarily aimed at regulating the material and process standards for electronic and electrical products. Its purpose is to eliminate six substances—lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers—from electrical and electronic devices, with a particular emphasis on lead content not exceeding 0.1%. The main substances tested under RoHS requirements are as follows in the table:
Restricted Materials


"Method for Testing Harmful Substances in Electronic Information Products" (hereinafter referred to as "the Testing Method," standard SJ/T 11365-2006) specifies the testing methods for harmful elements as required by RoHS. Among them, X-ray fluorescence spectroscopy (XRF) is established as a rapid and convenient screening method. XRF can be used to test standard samples of lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr), and bromine (Br). However, the results obtained based on the principle of XRF only represent the content of elements, meaning that if the screening test detects the content of chromium (Cr) or bromine (Br), even if it exceeds the standard, it does not necessarily indicate that the harmful substances (Cr VI) or flame retardants (PBB and PBDE) are in excess. This test result (indicating presence) is only a necessary but not a sufficient condition for the presence of harmful substances. This is why there are no limit values for non-compliance with these two harmful substances in the limit table.
