Determination of Short-Chain Fatty Acids Using the AnYiPu TQ8100 Triple Quadrupole Gas Chromatograph-Mass Spectrometer
Humans lack sufficient enzymes to degrade large amounts of dietary fiber. Undigested dietary fiber ferments to produce short-chain fatty acids (SCFAs), which are primarily generated in the colon. SCFAs not only provide energy for intestinal mucosal cells, promoting cell metabolism and growth, but also lower colonic pH, inhibit harmful bacteria, prevent gut dysfunction, suppress pro-inflammatory factors, and mitigate colitis. Additionally, they inhibit tumor bacterial proliferation, control proto-oncogene expression, promote tumor cell differentiation and apoptosis, and exert anti-tumor effects. The specific types and quantities of SCFAs determine their physiological impacts. Therefore, research into SCFAs can establish relationships between their profiles (types and concentrations) and human health. Due to their low molecular weight and boiling point, gas chromatography-mass spectrometry (GC-MS) is an excellent tool for SCFA analysis due to its superior qualitative capabilities and high sensitivity. However, biological matrices such as blood and feces are complex; triple quadrupole GC-MS offers superior interference resistance, making it more suitable for analyzing these complex samples. This study developed a method using the Amsys TQ8100 triple quadrupole GC-MS system to quantify 7 SCFAs: acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid, valeric acid, and hexanoic acid.

View DetailsChemisorption Analyzer Coupled with Amspec Small-Molecule Mass Spectrometry: TPD-MS Online Analysis for Deep Catalyst Mechanism Research
In the field of multiphase catalysis, chemisorption analyzers are the standard instruments for characterizing catalyst surface acidity, active sites, and adsorption/desorption behavior. Traditional chemisorption analyzers rely on TCD thermal conductivity detectors to collect signals, which only reflect total gas quantity changes. They cannot distinguish mixed gas components or identify intermediates and byproducts generated during temperature ramping, severely limiting the depth of catalytic reaction mechanism analysis. By integrating a chemisorption analyzer with an AMS small-molecule mass spectrometer to create a TPD-MS (Temperature Programmed Desorption-Mass Spectrometry) online coupled system, we establish a new dynamic online analysis solution. This approach connects the complete data chain of "temperature-product type-product concentration" for surface processes on catalysts, providing critical characterization capabilities for the development of novel catalytic materials.

Fully Self-Developed Breakthrough | ANYEEP TQ8120 GC-MS/MS Sets New Standard for Domestic Triple Quadrupole Mass Spectrometry
For years, China's high-end triple quadrupole gas chromatography-tandem mass spectrometry (GC-MS/MS) market has been heavily reliant on imported equipment. Imported instruments come with high acquisition costs, long lead times for core components, and steep maintenance fees. Moreover, their closed underlying technology makes it difficult to align with China's national standard testing methods and local detection needs for complex sample matrices, creating a major bottleneck for many testing laboratories and research institutions. To meet the critical industry demand for domestic substitution, Anyeep has launched the ANYEEP TQ8120 GC-MS/MS system. Designed to tackle the core challenges of replacing foreign technology, this instrument follows a path of full control over core technologies.
