For fast quantitative analysis one technique stands out:
NIR THE NEW SPECTROSCOPY
New developments in optics and electronics make NIR a front-rank analytical technique Today's spectroscopists are discovering the benefits of working in the NIR (near infrared) spectral region. Advanced NIR equipment offers signal-to-noise ratios that are orders of magnitude greater than conventional spectroscopies. And chemometric analysis techniques provide automated method development for research or routine applications. Precise and accurate NIR spectra provide superior quantitative and qualitative analysis with the advantage of minimal sample preparation. And because water and organic bands do not saturate in the NIR region, it's perfectly suited to the analysis of hydrocarbons, aromatics, aqueous solutions and biological samples.. .without dilution, solvent subtraction or extraction.
NIR can analyze raw, unprepared samples of liquids, powders, slurries, pellets and solids through a variety of convenient sampling devices: no solvents, discs or mulls required. As for speed, today's NIR spectrophotometers scan several times per second, to develop data 100 times faster than equipment of the 1970's. NIR's sensitivity proves valuable for qualitative analysis such as spectral matching, development of spectral libraries, and discriminant analysis. It's today's alternative to FTIR techniques where sample preparation limits the reproducibility of spectra. Pacific Scientific offers both research-grade and productionoriented NIR spectrophotometers for the food, pharmaceutical, petroleum, plastics and agricultural industries, as well as university labs.
