Linked gas chromatography-infrared-mass spectrometry
Analytical Chemistry, 1987For almost 20 years the idea of linking a gas chromatograph with both an infrared and a mass spectrometer to form an integrated analysis system (GC/IR/MS) has intrigued analytical chemists. For example, in one of the earliest GC/IR papers, which reported GC/IR spectra of 10-18 wavenumber resolution with microgram-level sensitivity, Low and Freeman ...

According to current practice the far-infrared region is considered to be that part of the electromagnetic spectrum between the sodium chloride prism cutoff (about 15 μ) and the wavelengths at which microwave techniques may be successfully employed. The farinfrared region tends to be pushed continually to longer wavelengths by the development of better

Infrared Spectrometry since 1945
Applied Spectroscopy, 1951The period since World War II has resulted in a steady growth throughout the infrared field. This growth has been mainly one of utilization and extension of wartime developments and techniques rather than one of fundamentally new discoveries. Even so, the process of utilization and extension has been so broad that the field has altered radically in the

Interferometric Spectrometry for Infrared Astronomy
1972In studies of the reflectivities and absorptivities of laboratory samples at frequencies below about 400 cm−1, the spectrometric technique which uses a two-beam interferometer has shown clear advantages over dispersive (grating) spectrometry, and the most sophisticated interferometers can in many respects better dispersive instruments at higher ...
