Liquid Chromatography
R. D. Laboratories, Inc. offers a wide variety of HPLC capabilities. Detectors we use include UV (Ultraviolet), Vis (Visible), RI (Refractive Index), Fluorescence and PDA (Photo Diode Array). The possible combinations of columns, mobile phases, gradients and detectors that can be used to separate and quantitate analytes are nearly limitless. This is one of the most powerful and useful techniques in pharmaceutical analyses. It is used extensively to assay both API’s and finished products. Peak purity, impurities and degradation are frequently examined during stability and validation studies. Our refrigerated, sealed auto-samplers work well for thermally labile and/or photo sensitive samples.
