Supplier: MACHEREY-NAGEL

Unmodified HPTLC silica layers available as glass plates with or without fluorescent indicator. The narrow fractionation of the silica particles features theoretical plate heights, which are one order of magnitude smaller than on standard silica layers. Thus, Nano-ADAMANT has the advantage of sharper separations, shorter developing times, and increased detection sensitivity with equal selectivity.

Supplier: Hach

These are used for determination of Ultra Low Range silica by the Heteropoly Blue Rapid Liquid method. Rapid Liquid™ methods offer an economical way to analyse multiple samples and to measure trace concentrations.

Supplier: Restek

General purpose Rt®-TCEP columns is ideal for aromatics and oxygenates in gasoline.

Supplier: Restek

Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and DEX columns continue to demonstrate stability after hundreds of temperature program cycles. By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. 2,3-di-O-ethyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane
