Instrument calibration, required for any accurate quantitative calculation, is a trivial process when performed correctly, but is also full of easily overlooked stumbling blocks. To minimize the risk of error associated with improper calibrations, na

BACKGROUND A major challenge in high-throughput clinical and toxicology laboratories is the reliable processing of chromatographic data. In particular, the identification, location, and quantification of analyte peaks needs to be accomplished with mi

This article describes the need for incurred sample reanalysis and suggests that the combination of a Bland–Altman plot and tolerance intervals can provide a visual evaluation of method performance. It also shows how the proposed combination is a t

Square hollow waveguides are used to integrate measurement of absorption with chip-based electrophoresis. The 50x50 microm liquid channel and 50x50 microm waveguide are etched as a negative pattern into a silicon master and replicated as a positive i

Two geometries of excitation/emission optics are compared for two-photon excitation of time-resolved fluorescence in capillaries. The test fluorophore is the enzymatic tag β-naphthylamine (BNA). Two 0.25 NA (numerical aperture) microscope objectives

The loss in sensitivity of two-photon excited fluorescence, when switching from a 1 cm cell format to square and cylindrical capillaries, is described quantitatively. Sensitivities are determined with calibration curves, and beam shapes are computed

Lasers are relatively recent additions to the analytical scientist's arsenal. Because of this, many analysts-whether their concern is research or some range of applications-are in need of a tutorial introduction not only to the principles of lasers,
