Voltammetric hplc sampler vials

1 天前 · The voltammetric oxidation behaviour of TDS has been inspected with different electrodes (GSPE) using tested nanoparticles in BR supporting electrolytes. The cyclic voltammograms of TDS display that the Cu NPs on ferrite base gives the uppermost anodic peak current at pH of 4.0 and a scan rate of 100 mV s -1 for 100 ng/ml of TDS as displayed in Table

The %Loss for nortriptyline of individual vials is calcu-lated as: A sample = peak area of glass vial A standard =average peak area of two QC controlled standards in polypropylene vials ( ) % 100% tan tan × − = s dard sample s A

The total-volume injection SIL-30AC autosampler features a pressure tolerance of 130 MPa as well as the world’s fastest sample injection (10 seconds), which dramatically reduces the total cycle time. It includes auto pretreatment and overlapping functions as standard, and an optional loop-injection method configuration to minimize delay volume.
