In this edition of the LCGC Blog, Amber Hupp of the College of the Holy Cross reflects on her childhood and talks about her journey recreating the scents from that long past.

Microplastics and nanoplastics have been identified in the lungs of wild birds using laser direct infrared (LDIR) chemical imaging and pyrolysis gas chromatography–mass spectrometry (Py-GC–MS), in the first multi-species evidence of these plastics in bird lungs.

Iowa State University researchers evaluated imidazolium-based ZILs with sulfonate and triflimide anions to understand the influence of ZILs’ chemical structures on polar analyte separation.

Using pyrolysis-gas chromatography and mass spectrometry, scientists from Fudan University and the Putuo District Center for Disease Control and Prevention detected and quantified microplastics in newborn stool samples.

In this first roundtable discussion focused on Women in Chromatography, LCGC International spoke with Diane Turner, Jacqueline Hamilton, and Caroline Gauchotte-Lindsay about what inspired them to pursue a career in chromatography and what challenges they faced along the way.

A new type of micro-gas chromatography column was fabricated using direct metal laser sintering (DMLS) to circumvent manufacturing issues faced by other micro-GC systems.

Thermal desorption and gas chromatography-tandem mass spectrometry were used to create a method for detecting airborne polycyclic aromatic hydrocarbon (PAH) samples.

A team of researchers has evaluated approaches in exposome research, highlighting sample preparation, MS-based platforms, and data acquisition strategies.

In Part II of our exploration of splitless injection, we will see that it is a surprisingly complex process, and that it is difficult to understand because we cannot see what is happening during the injection process. For this discussion, we will think of the injection process as beginning with the syringe plunger being depressed and ending with the start of a temperature program in the column oven. In most splitless injections, this process requires 30 s to 1 min. There are several band broadening and focusing mechanisms that affect the peak shapes, widths, and heights resulting from splitless injection.
