... approximately 185 nm is termed the vacuum ultraviolet; the optical paths for experiments in the vacuum ultraviolet are evacuated or purged with a nonabsorbing gas, such as helium. The long-wavelength low-energy end of the spectral region is defined by the fact that the eye can no longer detect light...

... or liquid form can be more challenging. The development and use of spectroscopic methods for elemental detection was first introduced by Bunsen and Kirchoff in 1860 with the discovery of cesium and rubidium by using a spectroscope invented in 1859 ( Ref 1 ). In 1934, the work of Lundergårdh demonstrated...

... spectrophotometric and photodiode array detectors, which monitor wavelength regions of interest so that qualitative identification by the spectrum is possible. Ultraviolet/visible detectors are nondestructive, and for a highly absorbing species, the lower limit of detection is about 10 −9 g of a component...

... transducer located beneath the sample, as illustrated in Fig. 1 . Because this ultrasound cannot travel through air (making it an excellent tool for crack, void, and disbond detection), a fluid couplant is used to bring the ultrasound to the sample. Distilled water, spectrophotometric-grade alcohol...
