  VOC’s analysis in atmospheric and indoor air

  • Gas Chromatograph-Mass Spectrometry

  Many substances harmful to human health are detected in atmospheric air. Even substances that are not at a concentration level that has a direct effect on human health may cause concerns of carcinogenicity after long-term exposure. Here we introduce shows applications for Gas Chromatograph-Mass Spectrometry (GC-MS) analysis of volatile organic compounds (VOCs) in the air.

  Drinking, mineral, natural and wastewater analysis

  Water is an irreplaceable resource not only for humans, but also for all animals and plants on earth. Water pollution is recognized as a major environmental problem. Water pollution has various effects on the global environment, such as causing health damage and changing ecosystems. To prevent water pollution, it is necessary to monitor pollution sources. Also, drinking water must be tested for contaminants. We provide analyzers and solutions for these water pollutants.

  Carbohydrates, benzopyrene and organic acids analysis in food

  Organic acids in food are important components that contribute to the deliciousness of foods, such as sourness and umami, and have also recently become a hot topic for their ability to promote digestion and have antibacterial effects. Analysis of organic acids is a useful approach in food development, but know-how is required to detect various organic acids specifically and with high sensitivity from samples containing many contaminants, such as foods.

  Vitamins and amino acids analysis in food

  Vitamins play an important role in metabolism in the body in minute amounts. Because the body cannot synthesize it or cannot synthesize it insufficient amounts, it must be obtained from food. Amino acids are the building blocks of proteins and play an important role in the human body for vital processes like cell formation and synthesis of hormones and neurotransmitters. High liquid chromatography and spectroscopic methods are wildly used for amino acids and vitamins content determination in food samples.

  Fatty acid composition analysis of edible oils and fats

  • Gas Chromatography
  • Gas Chromatograph-Mass Spectrometry

  Lipid is a general term for water-insoluble substances isolated from living organisms, and includes fats and oils, fatty acids, glycerin, cholesterol, etc. Among the lipids, omega-3 fatty acids such as DHA and EPA, which are abundant in blue fish, have been reported to have functional properties such as prevention of lifestyle-related diseases and dementia, as well as anti-inflammatory and anti-allergic effects. These are also popular as supplements. In the analysis of fatty acids, the common method is to extract the lipids from foods, convert the constituent fatty acids into methyl ester derivatives, and then analyze them using GC or GC-MS.

  Dioxins analysis in food and environmental samples

  • Gas Chromatograph-Mass Spectrometry

  Dioxins and polychlorinated biphenyls (PCBs) are extremely toxic substances that occur everywhere despite their danger. Therefore, the ability to reliably determine even the smallest quantities is particularly important. Until recently, the analysis of dioxins in foods and feeds was performed using magnetic sector GC-MS (GC-HRMS), which provided highly accurate quantitation. In recent years, the quantitative accuracy of GC-MS/MS has improved significantly.

  Elemental analysis in food matrix

  • Inductively Coupled Plasma Mass Spectrometry

  Toxic metals (arsenic, lead, cadmium, etc.) in foods must be controlled down to low concentration levels. Shimadzu atomic absorption spectrophotometers and ICP emission spectrometers offer highly sensitive analysis of trace elements in foods. Shimadzu’s product lineup also includes X-ray fluorescence spectrometers that can perform elemental analysis without sample pretreatment. These instruments are ideal for screening analysis and emergency analysis.
