Aside from the general chemicals that can be used for ion chromatography the Analytics-Shop further offers a wide range of other standards and reagents. In the following you can find numerous products from various well-known manufacturers such as Sigma Aldrich, Merck Millipore, Supelco and Fluka.
Gel filtration is a variation of chromatography where molecules are carefully separated according to their size and shape which makes this method very well suited for the separation of sensitive biomolecules. The basis of such filtration is filled with a special gel matrix column. For applications of gel filtration standards are needed in order to, e.g. determine the molecular weight. The manufacturer Waters offers a range of high quality standards for your laboratory applications.
The Gel Permeation Chromatography (GCP) is a variation of the liquid chromatography where it's possible to separate the molecules of dissolved substances according to their size. The conventional calibration solely takes place when a concentration detector (RI or UV) is applied. For the calibration usually severaldifferent-sizedpolymerstandardswithlowpolydispersities are used.In addition to theneedofthe separation column for a successful application, theuse of ahigh-qualitystandard is alsoindispensable.
The so-called internal standards are needed toperformaquantitative analysisin laboratorysamplesandwhen lossesofsamplecomponentsareexpected. Furthermore this calibration can be used to check the constancy of analyzing devices such as those by the manufacturer Mettler-Toledo. The Analytics Shop offers a selection of different calibration standards for your laboratory applications among others by Sigma Aldrich and Supelco.
