  • Advantages of In-House Generation of Nitrogen for HPLC With Evaporative Light Scattering Detection (.pdf)
    Evaporative light scattering detection (ELSD) is a universal detection technique for HPLC that provides a number of distinct advantages over other commonly employed detection methods such as UV-VIS absorbance, fluorescence, and electrochemical measurements. ./532226ed-c415-4104-b3c0-7fa66d907a22
  • Detection of Nitroarenes in Diesel Exhaust Using HPLC with UV and Fluorescence Detection
    and nitroarenes in diesel exhaust. A series of diesel exhaust samples spiked with nitroarenes were run on a Jasco HPLC equipped with an NPpak-P pretreatment column, an NPpak column for separation, and an NPpak-R column for reduction. Samples were run using gradient elution with methanol and water at a flow rate
  • Use of industrial waste water
    as that of the culture supernatants was determined using a Dionex 4000I HPLC (Dionex Corp., Sunnyvale, CA, USA) equipped with a pulse amperometric detector and gold electrode, using a 250 x 4 mm (I.D.) PA1 Carbopac column (Dionex Corp.) with inlet and oven temperatures of 30oC and 1.8 mM NaOH as eluent at a flow
