Delivers a resolving power of greater than 60,000 (FWHM) over a wide mass range of m/z 10-30,000.

Provides tunable resolution of 4,000 to 7,000 at FWHM at m/z 281.

Invented in the late 16th century, the microscope is arguably the oldest laboratory instrument. Yet despite its maturity, microscopy continues to evolve toward greater capabilities.

Dr. Rebecca Williams, director of the Microscopy and Imaging Facility at Cornell University, talks about her role in overseeing the imaging laboratory while pursuing independent research in the field.

Increasingly, analysts perform routine analysis where the action islocations of environmental interest, manufacturing suites, crime scenes, loading docks, and packaging facilities through transportable instruments.

Among the hyphenated mass spectrometry (MS) techniques, gas chromatography-MS (GC-MS) and high-performance liquid chromatography- MS (LC-MS) are the most notable. These methods combine the resolving power of high-resolution chromatography with the specificity and sensitivity of MS.

Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum.
