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
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.
Ethanol standards are widely used in forensic and toxicology applications for determination of blood alcohol content. Results of blood alcohol testing have significant legal implications and are frequently used as evidence in courts of law. The blood alcohol analysis process
Packed columns continue to be used in multi-column, multi-valve configurations for the determination of BTU content in natural gas and natural gas liquids as described in Gas Processors Association (GPA) Methods 2261 and 2177, plus American Society for Testing and
Alkylphenols are starting materials for the synthesis of alkylphenol ethoxylates, which are widely used as non ionic tensides, dispersive agents in paper and leather manufacturing, emulsifiers for pesticide formulations and as auxiliary agents for drilling and flotation.
ionic liquids can successfully be used as viable GC stationary phases. These consist of two or more organic cations joined by a linkage, and associated with... improved inertness for polar analytes was the inspiration for the development of SLB™-IL (i-series)
Paprika is a spice made from dried sweet peppers, and is used for flavor and color in many types of cuisine. Contamination with polynuclear aromatic hydrocarbons (PAHs) can occur when pepper plants are exposed to these pollutants in the environment
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination
Bisphenol A (BPA) is suspected to be an endocrine disruptor. Regulations on specific migration limits (SML) from food contact materials are getting tighter (EU 2018/213) requiring more sensitive determinations. An overcoated SPME fiber provides the durability necessary for direct
