Agilent Technologies introduces new ZORBAX solvent saver columns to reduce laboratory waste, solvent costs

PALO ALTO, Calif., Feb. 25, 2003

Agilent Technologies Inc. (NYSE: A) today introduced a variety of new ZORBAX Solvent Saver columns to help reduce solvent purchase and waste disposal costs in liquid chromatography (LC) and LC/MS (mass spectrometry) applications. Now available, the Agilent ZORBAX Solvent Saver (5Ám) and Solvent Saver Plus (3.5Ám) can be easily applied to new or existing HPLC methods.

Agilent's 3.0 mm internal diameter (id) Solvent Saver columns provide significant advantages over the larger 4.6 mm columns, reducing mobile phase usage and waste by 60 percent and improving signal-to-noise ratio by two to three fold while still delivering the same resolution and selectivity. The flow rate for 3.0 mm columns are 40 percent of the flow rate of the 4.6 mm id columns at the same linear velocity; this decreases solvent purchase and waste disposal costs at the same linear velocity.

The ZORBAX Solvent Saver columns deliver optimal performance at intermediate flow rates effective for common MS interfaces such as electrospray, atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo ionization (APPI) sources. This enables scientists to conveniently switch between sources without changing the column or method conditions.
