Where electronic integrators are used, it may be convenient to determine the resolution. The tailing factor is determined by drawing a perpendicular line from the peak centre to the baseline of the peak. STEP 1 Data can also be collected for manual measurement on simple recorders or on integrators whose capabilities range from those providing a printout of peak areas to those providing chromatograms with peak areas and peak heights calculated and data stored for possible reprocessing. It exhibits an extremely high response to compounds containing halogens and nitro groups but little response to hydrocarbons. Available commercially as Polyethylene Glycol Compound 20M, or as Carbowax 20M, from suppliers of chromatographic reagents. leading edge of the peak at one-twentieth of the peak height. It is a selective detector that shows little response to hydrocarbons. Presumptive identification can be effected by observation of spots or zones of identical. Potentiometric, voltametric, or polarographic electrochemical detectors are useful for the quantitation of species that can be oxidized or reduced at a working electrode. Multi-wavelength detectors measure absorbance at two or more wavelengths simultaneously. The thermal conductivity detector employs a heated wire placed in the carrier gas stream. Precautions must be taken against allowing the solvent to run down the sheet when opening the chamber and removing the chromatogram. 105 106 Plate height (H) (synonym: Height equivalent to one theoretical plate (HETP)) 107 Ratio of the column length (L), in micrometers, to the plate number (N): 108 H = 109 110 111 Plate number (N) (synonym: Number of theoretical plates) L22A cation-exchange resin made of porous polystyrene gel with sulfonic acid groups, about 10 m in size. Tailing Factor will be called Symmetry Factor. Some parameters which can be checked using the System Suitability Testing are: Resolution Retention time Pressure Column efficiency Repeatability Plate Number Tailing factor Signal-to-noise ratio Let us look at some of these parameters. L30Ethyl silane chemically bonded to totally porous silica particles, 3 to 10 m in diameter. USP Tailing and Symmetry Factor per both the EP and JP. High-pressure liquid chromatography (HPLC), sometimes called high-performance liquid chromatography, is a separation technique based on a solid stationary phase and a liquid mobile phase.
