GC Columns

Incorporating a higher level of inertness than previous offerings, the columns are stable up to 300/320 °C

The new LC and GC columns for the analysis of polycyclic aromatic hydrocarbons (PAHs) include Kinetex® 3.5µm PAH and Zebron™ ZB-PAH

The most significant equipment-related trend in bioprocessing over the past 15 years has been the replacement of reusable glass and steel equipment by single-use plastics.

Finding the right column for your application can be tough. We aim to make that process a little easier with this year's guide.

Chromatographers often need to balance the convenience of universal-use columns against the sensitivity and resolution of specialized columns. “Where labs may at one time have employed a nonpolar, all-purpose column, they now seek columns engineered for chemical families or even specific methods,” says Timothy Anderson, GC products manager at Phenomenex (Torrance, CA).

As regulators have redefined environmental methods for low-abundance analytes, and demanded the analysis of more analytes, column manufacturers have done well to provide greater sensitivity and selectivity.

Today, the number of distinct GC column stationary phases has grown

The history of chromatography dates back to the mid-19th century
