nalysis of the omega 3 fatty acid profiles from fish oil capsules and salmon, highlighted through the use of 2 GC columns of different selectivity for analysts who wish to perform confirmatory analysis.
We offer a variety of ethyl acetate products suitable for applications including GC, HPLC, UHPLC, and LC-MS. We also supply multiple options for anhydrous ethyl acetate and ACS grade ethyl acetate.
GC Analysis of Xylene Isomers on SLB®-IL60 - The cresol (methylphenol) isomers are also precursors to many chemicals. This chromatogram of a mix of aromatic and methylphenol compounds was generated using an SLB-IL60 ionic liquid column. Its interaction mechanisms allow
Our GC solvents have been specially developed and tested for ECD, FID and MS detection or for headspace gas chromatography to ensure accurate, reliable and reproducible analytical results.
Carbon Molecular sieves (CMS) are a versatile range of adsorbents that can be tailored for specific applications. Supelco® scientists have been synthesizing synthetic CMS carbons for several decades, starting from tailoring of the starting polymers/copolymers, to modifying the final properties
QuEChERS is a ‘Quick, Easy, Cheap, Effective, Rugged and Safe’ sample cleanup method used to prepare food and agricultural samples for pesticides analysis. QuEChERS is based on the Solid Phase Extraction (SPE) technique of sample preparation.
Measurement of acetic acid vapor in the workplace using passive sampling SPME and on-fiber derivatization with 1-pyrenyldiazomethane: Comparison with active sampling.
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
The manufacturing of elastomers makes wide use of 1,3-butadiene (CAS No. 106-99-0) and isoprene (2-methyl- 1,3-butadiene, CAS No. 78-79-5). Both compounds are classifi ed as carcinogenic by the International Agency for Research on Cancer (IARC). 1,3-Butadiene is currently listed in
Larger porous shell particles with narrow particle size distribution, used in Supelco's BIOshell™ columns for the reversed-phase U/HPLC analysis of peptides and proteins, provide increased efficiency per unit pressure drop.
Volatile organic compounds are trapped by adsorption and recovered by thermal desorption, analysis is performed by capillary gas chromatography and FID or MS detection.
This article shows the use of BugBuster® and Benzonase® as protein purification tools to extract recombinant proteins from E. coli and to reduce the viscosity of the extract.
