Analysis of Pesticides in Baby Food Using Triple-Quadrupole GC–MS-MS
June 1st 2013Contamination of food products with pesticides is a growing concern because of recognized damaging health effects. This concern is particularly acute for baby foods because of the vulnerability of young children to harmful effects of synthetic chemicals, particularly pesticides. This application note presents results for analysis of trace levels of 24 organophosphorus (OP) pesticides in baby foods using the Shimadzu GCMS-TQ8030 triple quadrupole GC–MS-MS.
Determination of Additives in Beverages Using Ascentis Express Columns
June 1st 2013Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable.
