Enviro-Clean HLDVB 500mg/6mL (ECHLD156-P)

Recently the US EPA published a list of 30 UCMR4 (the 4th Unregulated Contaminant Monitoring Rule) analytes which may potentially be present in tap water but are not yet subject to EPA’s drinking water standards set under the Safety Drinking Water Act. 4 among the 30 UCMR4 compounds, including o-toluidine, quinoline, butylated hydroxyanisole (BHA), and dimethipin, are determined by EPA method 530 using solid phase extraction (SPE) and GC/MS detection. This application method demonstrates the analysis of a sample of preserved drinking water using SPE and GC/MS.

EPA Method 1694 was published in December 2007 as a screening method for the analysis of 73 pharmaceuticals and personal care products (PPCPs) in environmental samples, including water (wastewater, surface water and drinking water). The PPCPs include common prescription drugs, veterinary drugs, over‐the‐counter medicines, dietary supplements and other consumer products. This application note outlines a SPE procedure using UCT’s Enviro-Clean® HL DVB polymeric sorbent for the determination of 64 PPCPs in water according to EPA Method 1694.

Patulin is a naturally occurring mycotoxin that is produced by several species of fungi, such as Penicillium and Byssochlamys, and has been implicated as a possible carcinogen and teratogen, although an official designation has not yet been made. The main risk arises when unsound fruit is used for the production of juices and other processed products. The amount of patulin in apple juice is also viewed as a measure of the quality of the apples used in production. This application note outlines a simple solid-phase extraction (SPE) procedure for the low level detection of patulin in apple juice.
