Butyric acid methyl ester

ROTICHROM® GC
Przykłady działania: są łatwopalne; ciecze tworzą mieszaniny wybuchowe z powietrzem; w kontakcie z wodą wytwarzają łatwopalne gazy lub są samozapalne. Bezpieczeństwo: trzymać z daleka od otwartego ognia i źródeł ciepła; szczelnie zamknąć naczynia; przechowywać w miejscu ogniotrwałym.
Przykłady działania: prowadzą do uszczerbku na zdrowiu, drażnią oczy, skórę lub organy układu oddechowego. W dużych ilościach prowadzą do śmierci. Bezpieczeństwo: jak wyżej, w razie podrażnienia skóry lub kontaktu z oczami przepłukać wodą lub innym odpowiednim środkiem.

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.

Oils and Greases

Carl ROTH oils and greases are carefully manufactured from selected raw materials. They are of high purity and extensively specified. Therefore, they are suitable for a broad range of applications.


Fatty Acid References

In the field of lipid analysis we put an extensive collection of reference substances and reference mixtures at the analyst’s disposal.

All reference mixtures are prepared from pure components which are carefully tested for purity by TLC and GC.

Precise weighing and a final check guarantee the precision of the mixture. A certificate comes with each product.
