Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.

Such drugs can have mind-altering effects, with some causing dependence and addiction.Polymeric MaterialsPolymeric materials are widely used in industries ranging from biomedical devices to packaging and electronics. Research into these materials focuses on their properties, including strength, flexibility, and degradation. Advances in polymer science have enabled the development of more sustainable and high-performance materials. Explore the best polymeric material products in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Sample HandlingProper and careful handling of samples is important in scientific studies to ensure the integrity of specimens. This will prevent deterioration and cross contamination, and improve the accuracy of sample tracking procedures.Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.Crude OilThe chemical evaluation of the complex combination of hydrocarbons and organometallic compounds found within crude oil. The results provide data on the chemical characteristics of a sample for petroleum testing laboratories.WineFood TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Environmental Forensics
