  • What auxiliary substances should a chemist consider?
  • While the solvent may be the most obvious “auxiliary substance” to a chemist, there are many other substances that should also be considered. Drying agents, chromatographic column packings, and separation agents (e.g. saline solution, acid/base wash, activated carbon) are other examples of auxiliary substances used during or after a reaction.
  • Which purities are available for analytical applications?
  • Premium range of specialty pure gases for analytical applications We offer a choice of two purities for helium, argon, nitrogen, hydrogen, air and oxygen available in gaseous form or liquid form: ALPHAGAZ™ 1: the commitment to quality for % to 10 ppm analysis.
  • What auxiliary substances are required for a chemical synthesis?
  • It depends on whom you ask. The average synthetic chemist, when reading this principle (Fig. 1), would think of all of the auxiliary substances required for a chemical synthesis and subsequent product purification: solvents, drying agents, column packing agents, etc.
