Analysis of polychlorinated dibenzo-p-dioxins (PCDDs), furans (PCDFs), and biphenyls (PCBs) by environmental laboratories in North America has continued for many years. Increasingly analytical needs have focused on complete separation of PCDD/Fs and PCBs during sample processing with all existing 209 PCBs being analyzed. A semi-automated method (EZPrep), which combines elements of fully manual and fully automated procedures, was developed and tested. It uses pre-packaged silica, alumina, and carbon column kits for sample cleanup. The system uses a vacuum pump to elute solvents through these chromatographic columns for sample purification and preparation. The method described here allows for the sample extracts to be in toluene. With this method all PCBs are collected in one fraction and all PCDD/Fs in another fraction. 13C labeled recoveries for 10 g soil extracts were 75 to 95% for PCDD/Fs and 75 to 90% for PCBs. Similar tests for 2 g salmon extracts yielded recoveries of 80 to 105% for PCDD/Fs and 75 to 95% for PCBs. The semi-automated method can process six samples in parallel within a 50 min period.

Evaporation-free extraction (no drying down) is highly desirable because of its reduced cost and pollution, higher speed, and less possibility for contamination and conversion. Presented in this article are four types of evaporation-free extraction that are widely applicable. The first one is for the determination of didanosine over the range of 25.02-2502.00 ng/mL by injecting solid-phase extraction (SPE) eluate directly. The second is for the determination of betamethasone phosphate over the range of 2.51-250.60 ng/mL by injecting SPE eluate after pH adjustment. The third is for the determination of sumatriptan over the range of 0.99-99.40 ng/ mL based upon SPE with high organic washing and low organic elution. The fourth is based upon automated dilution after protein precipitation for the determination of raloxifene-4′-glucuronide and raloxifene-6-glucuronide over the ranges of 2.02-202.40 ng/mL and 0.40-39.95 ng/mL, respectively.

This article presents information on gel-permeation chromatography (GPC). GPC is a highly effective postextraction cleanup method for removing high molecular-weight interferences such as lipids, proteins, and pigments from sample extracts prior to analysis. If sample extracts with high-lipid content are injected onto a gas chromatography (GC) column, the injection port and column can easily become contaminated, resulting in recovery losses and poor chromatography. The collected fractions were evaporated using the RapidVap N2 system and reconstituted in appropriate solvent for GC analysis.
