Analysis of Residual Solvents in Hemp Extract by Headspace SPME-GC/MS
The use of solid phase microextraction (SPME) allowed for the straightforward, fast, sensitive, and accurate GC/MS determination of the residual solvent content of spiked and unspiked samples of hemp extract.
Quantifying Picogram Concentrations of Aflatoxin M1 in Liquid Milk Using SPE Cleanup and LC/MS Analysis
Fast method for the cleanup, analysis, and quantification of aflatoxin M1 in milk samples to EU regulatory standards (0.025 μg/kg).
Increase Removal of Fat and Pigment from Avocado Extracts Prior to GC-MS Analysis of Pesticide and Metabolite Residues
Supelco's Z-Sep+ sorbent effectively removes fat and pigment interferences from avocado, with good pesticide recoveries; it removes more matrix than traditional PSA/C18 sorbent, and produces a lower background for GC-MS analysis.
Analysis of Polychlorinated Biphenyls in Fish Oil Using Supelclean EZ-POP NP, Silica Gel SPE, and an SLB-5ms GC Column
Polychlorinated biphenyls (PCBs) were once widely used in many industrial and commercial applications such as insulating fluids, dielectrics, and lubricants. This included their extensive use in electrical transformers. PCB use has been banned in many countries, and the Stockholm Convention...

Analysis of Vitamin D in Milk and Infant Formula using UHPLC/MS/MS per AOAC Method 2011.11
While quantitative analysis was performed for Vitamins D2 and D3, the samples were scanned for the presence of the 25-hydroxy metabolites.
GC Analysis of Fatty Acids in Walnuts and Peanuts
Determination of the fatty acid composition of nuts using established methods for GC analysis on capillary columns of 3 selectivities: Omegawax, SP-2560, and ionic liquid based SLB-IL111.
Analytical Method: Nitrite in potato instant powder
Photometric determination using the Griess method subsequent to extraction
Determination of Bisphenol A in Drinking Water
A comprehensive sample preparation and analytical procedure was developed by Supelco for determining BPA in drinking water.
Enzymatic Galactose and Lactose Assay Protocol
This assay protocol is suitable for the colorimetric/fluorometric detection of Galactose and Lactose in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples using the Galactose and Lactose Assay Kit (MAK011). In this assay kit, galactose is...
Analysis of Active Cannabis Compounds (Cannabinoids) in Edible Food Products: Gummy Bears and Brownies
Rapid potency testing of marijuana-infused edibles using LC/MS on a biphenyl stationary phase detected eleven cannabinoids.
Better Tools for Fast and Convenient Patulin Analysis
For a precise detection of patulin, we offer SPE cartridges for purification and a comprehensive range of analytical standards.
Reduce Matrix Background and Improve Overall Analyte Recovery for the Analysis of Pesticides in Beef Kidney
Supel QuE Z-Sep+ was successfully demonstrated for cleanup of beef kidney matrix, providing reduced background and less interference in the GC-MS analysis of the target pesticides
Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17944
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...

Analytical Method: Urea in Milk (Photometry)
Photometric determination with Diacetyl monooxime in the sample clarified with Trichloracetic acid
Food & Beverage Analysis: Sugars & Saccharides
Simple sugars using hydrophilic interaction chromatography (HILIC): Chromatographic analysis of simple sugars can be challenging because these compounds are highly polar, uncharged, and lack a chromophore. The preferred mode of HPLC separation is HILIC because it provides the advantage of...
Cannabis Terpene Analysis by Headspace SPME GC/MS
High-resolution profiling of terpenes and terpenoids to identify fragrance compounds and distinguish hops and cannabis varieties using SPME-GC/MS.
Extraction and Analysis of PAHs from Grilled Hamburger
A QuEChERS approach was effectively used to extract PAHs from grilled hamburger meat; the SPB-608 GC column provided the selectivity necessary to resolve all but one isomeric set.
Determination of Additives in Beverages Using Ascentis® Express Columns
RP-Amide and HILIC, both amenable to the analysis of polar compounds, were successfully used to resolve several beverage components, including sugars, vitamins, sweeteners, preservatives, and caffeine.
Fast Extraction and Low Level Detection of Chloramphenicol in Shrimp
