Design of an Ultra-High Resolution SEM for Enhanced Analysis
The column is equipped with a well-known single-pol e bjective lens [2] that creates a strong magnetic  field around the sample, thus dramatically decreasi ng optical aberrations. Design optimization and combining the magnetic immersion field with the ele ctrostatic field [3] further improves the resolutio n to less than 1.1 nm at 1 kV. For analytical purpose s (EDS or EBSD) or for use with a FIB column however, the immersion magnetic field becomes a com plication due either to curvature of signal electron trajectories or beam splitting of ion-isot opes.

Silver–Gelatin Method for the Determination of Trace Amounts of Carbon Monoxide in Air
The use of silver–gelatin complex was found suitable for the determination of trace amounts of carbon monoxide in air. Silver–gelatin complex is reduced by carbon monoxide to give intensely colored sol. Measurement of the color intensity of the stable silver sol enables the determination of carbon monoxide successful under various environmental conditions. The detection limit is 2–100 ppm. The relative standard deviation for the determination of 10 ppm carbon monoxide is 2.6%.
