History of Absorption Analysis
| Advantageous Features |
|---|
| AD 1666, Newton used prism to dispersed sun light |
| AD 1729, Pierre Bouguer formulates Lambert-Beer law |
| AD 1802, Fraunhofer related dark lines with Elements, started modern spectroscopy |
| Earlier AD 1950’s, UV-Vis spectroscopy using lamps spread |
| AD 1954, First Maser invented, time standard started using absorption frequency |
| AD 1960, First Laser invented |
| AD 1962, First Diode laser invented |
| AD 1969, desktop FTIR with micro computer introduced |
| AD 1975, GC-IR and GC-MS introduced, but due to sample volume limit, GC-IR give away to GC-MS |
| AD1990, Cavity Enhanced Absorption Demonstrated, pathlength significantly extended from meters to kilometers |
| AD1994, Quantum Cascade laser invented |
| AD2008, HWG+QC laser demonstrated, sample volume shrank from ml to μL, performance of GC-IR improved 3 orders of magnitude, GC-IR promises to compete with GC-MS |
