ANALABS is your exclusive source of supply for ANASIL — a completely new and different S1O2 adsorbent developed specifically for ThinLayer Chromatography. Time after time, in direct comparison with conventional silica gel preparations, ANASIL has provided faster analyses with no sacrifice in separation efficiency. It is available either with or without binder — the latter being especially suited for the analysis of lipid and other complexes where the presence of binder interferes with normal migration of components.
STATIONARY PHASES The ANALABS line of over 200 specialty and general-purpose phases is believed to represent the most complete assortment available from one, convenient source. Included are a wide variety of specially synthesized polymers of varying degrees of polarity for advanced GC research. Other specialties are the highly polar neopentyl polyesters of adipic, sebacic, and succinic acids — plus XE60, the most selective of the silicone phases — for the analysis of steroids, sterols, bile acids, terpenes and other high molecular weight compounds.
COLUMN PACKINGS TO ORDER! All ANALABS phases can be purchased coated on Anakrom (and certain other supports, as well) in any standard mesh size and in any concentration. Each lot is pretested and a chromatogram kept on file. Also, Analabs will produce completely pretested and conditioned packed columns — glass, stainless steel, or copper — meeting your exact specifications for any instrument.
