Column Packing
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ R, 80-100 mesh
Porapak™ R with Amberlite™ XAD-4 maybe useful for chromatographic sampling of polar and nonpolar low-volatility compounds.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ QS, 80-100 mesh
Porapak™™ QS packed columns maybe used for the analysis of sulphur-containing gases by gas-solid chromatograpy.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ R, 50-80 mesh
Porapak™ R with Amberlite™ XAD-4 maybe useful for chromatographic sampling of polar and nonpolar low-volatility compounds.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ QS, 100-120 mesh
Porapak™™ QS packed column maybe used for gas-solid chromatographic determination of moisture in lyophilized pharmaceutical products.
MilliporeSigma™ Supelco™ GC Stationary Phase, 1,2,3-tris(2-Cyanoethoxy)propane (TCEP)
Diviylimidazolium bistriflamide ionic liquid which improves oxygen and moisture stability
MilliporeSigma™ Supelco™ Molecular Sieve Adsorbent, Matrix Molecular Sieve 13X, 100-120 mesh
Molecular sieves are synthetically produced zeolites (naturally occurring aluminosilicate minerals), and are characterized by pores and internal cavities of extremely uniform dimensions.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ N, 80-100 mesh
Stainless steel columns packed with Porapak™™ N and molecular sieve maybe used for the separation and determination of micro-quantities of formic, acetic, propionic, isobutyric, butyric, 3-methylbutyric and valeric acids present in biological media as end-products of microbial fermentation.
