Incorporating a higher level of inertness than previous offerings, the columns are stable up to 300/320 °C
Learn the most common separation modes used by readers, and more from the latest chromatography columns survey results
The new LC and GC columns for the analysis of polycyclic aromatic hydrocarbons (PAHs) include Kinetex® 3.5µm PAH and Zebron™ ZB-PAH
The sample matrix can have an effect on the type of surface chemistry that is applied to the column being used
Although most chemists take classes in the theory of gas chromatography (GC), they learn operation and troubleshooting mostly through hands-on operation and laboratory lore.
Find out the most common phases used and more in our latest survey results.
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.
