WebBurdick & Jackson solvents are arranged in order of increasing dielectric constant, the ratio of the electrical capacity of a capacitor filled with the solvent to the electrical capacity of the evacuated capacitor (at 20°C unless otherwise indicated). WebJan 10, 2014 · Pure hexane, deuterated hexane and 1,3,5-tri-tert-butylbenzene (TTBB) were tested as “unretained compounds” for all columns. Each sample was filtered through a 0.2 μm syringe-driven filter (PTFE, Millipore, Billerica, MA, USA) before injection. All retention data were expressed in volume units and are the average of triplicate injections.
