Wetting and equilibration of C18 columns for flash chromatography are best performed at the highest possible pressures/ flowrates in order to remove the air trapped inside the porous material. That will make more C18-sites activated and accessible during the chromatography run.
This application note describes a procedure for sample pre-treatment and extraction of THC and its metabolites from human nail samples, using the Biotage® Lysera for matrix pulverisation, and pre concentration of the sample prior to clean up using ISOLUTE® SLE+ supported liquid extraction.

The scope of this application note is to demonstrate the process used to extract diquat and paraquat from reagent water using the Biotage® Horizon 5000 in tandem with the ISOLUTE® C8(EC) 500 mg/6 mL solid phase extraction cartridge.
This application note demonstrates recoveries of all the analytes within tables 1–2 of EPA method 625.1 (plus a few analytes from table 3) obtained using the Biotage® Horizon 5000 with Atlantic® 8270 One Pass solid phase extraction disks, 8270 Carbon Cartridges Max-Detect cartridges, and 1.0 Micron Atlantic® Fast Flow Pre-Filters for analyte extraction. The DryDisk® Solvent Drying System and the TurboVap® II are used for solvent drying and concentration and analysis is by GC-MS.
There are several different extraction methods that can be used to extract synthetic benzodiazepines from biological matrices such as urine and blood. This application note evaluates three common extraction techniques, detailing the methodology used, and comparing results in terms of analyte recovery and matrix effects.
