In the Lab, Take the High Ground
Thursday, March 14, 2013
So the sequester is here. Hopefully it will be shallow and short. Personally, I fear the austerity attitude will infect the private sector just at the time our recovery is accelerating. read more
State-of-the-Art Separations With Convergence Chromatography
Thursday, March 07, 2013
Supercritical fluid chromatography (SFC) has many potential advantages, including rapid separation of chiral analytes and separation by hydrocarbon class (i.e., saturates, olefins, and aromatics). Yet... read more
The State-of-the-Lab in 2013
Wednesday, February 27, 2013
Benchmarking—the process of comparing performance of peers or peer groups—is useful in understanding and evaluating relative performance. It helps manage, since one can compare a particular group with... read more
