HPLC Separation of Saccharin and Sorbitol
October 14, 2010
Sorbitol and saccharin are two sugar substitutes used in food and drinks. Separation of sorbitol and saccharin was achieved on a Primesep N HILIC column using acetonitrile/water with ammonium formate. Compounds were monitored by combination of UV and ELSD. Method is compatible with LC/MS detection.
Application Column
Primesep N
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.

Separation of Alginic Acid and Related Products
August 22, 2008
Alginate is used in various pharmaceutical preparations. Chemically, it is a linear copolymer with homopolymeric blocks of (1-4)-linked ?-D-mannuronate (M) and its C-5 epimer ?-L-guluronate (G) residues, respectively, covalently linked together in different sequences or blocks. Alginic acid can be separated from benzoate, citric acid and saccharin by mixed-mode chromatography on Primesep C HPLC column. This method can be used to quantitate alginic acid, citric acid or saccharin in complex mixtures. Various detection technique can be used (UV, ELSD, LC/MS), based on mobile phase selection.
