Versatile Protein Identification Using AP-MALDI Ion Trap Mass Spectrometry (PDF)

New developments in matrix-assisted laser desorption ionization (MALDI) technology enable decoupling of the ionization source from the time-of-flight mass analyzer for operation at atmospheric pressure (AP-MALDI). This technique also can be integrated with other types of mass analyzers, such as the ion trap.

Radio Frequency Glow Discharge Optical Emission Spectroscopy: Depth Profiling Analysis of Thin Anodic Alumina Films as Potential Reference Materials (PDF)

The need for reference materials that can be applied in the area of thin films analysis has long been realized but is still, in general, under-addressed. Alumina films of single-micrometer thickness, having either fine distributions of impurities or delta function impurity marker layers, can be prepared routinely by anodic oxidation of electropolished aluminum specimens in appropriate electrolytes. Selected films were examined by transmission electron microscopy (TEM) and analyzed by radio frequency glow discharge optical emission spectroscopy (rf-GD-OES), providing very rapid, yet high-resolution, depth-resolved analysis of these electrically insulating materials.

The Hyphenation of HILIC, Reversed-Phase HPLC, and Atmospheric-Pressure-Ionization MS

Hydrophilic interaction liquid chromatography (HILIC) and reversed-phase high performance liquid chromatography (HPLC) are complementary techniques in the separation of organic molecules with a broad band of polarity. Both separation variants can be operated easily with volatile and water-miscible solvents (for example, ammonium acetate aqueous solution and acetonitrile). Thus, a hyphenation of both liquid chromatographic techniques with atmospheric pressure ionization (API) and mass spectrometry (MS) seems to be a consequent step.
