What is Really in Your Detergents? NMR as a Tool for Composition and Competitive Intelligence

1 May 2016

The report in this application note details some of the compounds commonly found in commercial detergents. The study presents a comparison between major brands, and the “bargain brand” counterparts, using NMR to analyze the constituents qualitatively and quantitatively.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.NMR and EPR SpectroscopyNuclear magnetic resonance (NMR) spectroscopy is used to resolve the local chemical environment of atomic nuclei with spin, revealing information on molecular structure, dynamic processes and chemical reactions of organic molecules, from proteins to synthetics. Electron paramagnetic resonance (EPR) also known as electron spin resonance (ESR) spectroscopy is used to detect and quantify paramagnetic species in a sample, including free radicals as transition metal ions. By immersing the sample in a strong magnetic field, both NMR and EPR spectrometers probe the sample with either radio waves or microwaves respectively. A range of benchtop, solid-state and time domain NMR spectrometers & EPR spectrometers are available, as well as NMR tubes, NMR solvents, software, coils, and magnets.

For instance microplate washers can be programmable, combined with reagents dispensers and used for applications such as ELISA, multiplex assays and PCR clean up.Sample ManagementSample management systems include sample storage devices such as freezers and plate storers, sample environment enclosures and sample organization, retrieval and sorter systems. Useful system features include high-throughput, automation, robotic arms, automated liquid handling and associated database systems. Accessories in sample management include barcode scanners, heat sealers and tubes.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.Robotic InstrumentsRobotic instruments can be used for high-throughput automation of many lab processes. Such processes use instruments for assays like cell based assays and ELISA, for sample preparation like shakers, centrifuges and incubators, and for analysis such as sequencing and western blot analyzers. Useful features of robotic instruments include speed, reproducibility, barcode readers, software and automation.Robotic WorkstationsRobotic workstations are automated platforms enabling the user to perform high-throughput, multi-application processes, from sample preparation tasks such as PCR set-up, DNA purification and NGS library preparation, to integrated sample prep and analysis workstations. Automation makes processes consistent, fast, precise and fully walk-away. Find the best robotic workstations in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Automated Liquid HandlingAutomated liquid handling equipment is used to mix, dilute and dispense allotted volumes of liquid into microplates and other vessels automatically. The robotic, liquid handling arms can dispense from single channel to 3456 multichannel as well as operate nanoliter dispensing, enabling high throughput of samples.

These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Quality ControlQuality control is needed in all production processes. Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria. Compound IdentificationQuality TestingQuality testing ensures that products meet required specifications and safety standards in various industries, including pharmaceuticals, food, and materials. It is essential for maintaining product quality and consumer safety.

They are essential in the treatment of infections and in preventing disease spread. Explore antibiotics research and diagnostic tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Compound ScreeningCompound screening is a method used to discover specific compounds that could be promising candidates for pharmaceutical use. This potential is identified when compounds interact with the target protein during screening and could therefore be carried forward in the drug development process.
