Reference Substances ROTICHROM® HPLC/TLC/GC

for Chromatography

Pure reference substances are essential for precise analysis. They are used for identifying compounds by retention time, for calibrating detectors, and for eliminating errors in quantification of the sample compounds.

Peak areas are proportional to sample quantity in all chromatographic methods. For precise quantitative analysis, however, it is necessary to calibrate the detector as the signal may significantly vary with different substances.

To avoid errors during sample preparation and injection, an internal standard should be used in any case. The standard must not be present in the sample, however, its chemical and physical properties ought to be the closest possible to the analytical targets. It must be well resolved in the chromatogram within the same range of retention time as the sample. Before sample analysis, a given volume of standard is added, and all clean-up procedures are made with the sample containing the standard. Quantitative errors may be compensated by comparing the peak-areas of the sample with that of the internal standard.


Reference Substances for GC

ROTICHROM® GC
Carl ROTH offers an extensive range of reference substances for gaschromatography from the substance groups of alkanes, alcohols, ketones, esters, aromatic compounds, and much more. Their GC purity allows an accurate analysis.

The ROTICHROM® GC substances come with a certificate of analysis and a GC chromatogram enclosed in the outer packaging.
