Application Column
Newcrom A
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.

Nickel Contamination in Hydrogenation Products
November 14, 2005
Primesep 100 allows the quantitation of nickel cation in a hydrogenation product. Nickel is retained by cation exchange and the hydrogenation product is retained by hydrophobic, reversed-phase mechanisms. Adding an ELSD detector to the system allows detection of nickel which was not possible with UV alone. The separation uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) with evaporative light scattering detection (ELSD) and UV detection.
Application Column
Primesep 100
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
