| Before the end of that century, astronomers knew the answer to that question, thanks to spectrography. |
|
| Peirce was an acquaintance of Henry Rowland and, like him, conducted research on color spectrography. |
|
| A fortuitous recent result of asteroidal spectrography found that the object under observation was, in fact, a nearly dormant comet. |

|
| Their concentration in the gold after parting can be determined by arc spectrography. |
|
| The precise alloy of this aluminum could not be determined by energy dispersive x-ray spectrography. |
|
| This is also true of optical metrology, microscopy, spectrography and lens guides in different areas of application. |
|
| The results of these field trials are analysed in our state of the art laboratories in Tienen both by observation and with the help of techniques such as chromatography and spectrography. |
|
| Lot analysis is achieved through Littrow-type spectrography which ensures that the total maximum impurity level of all elements does not exceed 2 ppm. |
|
| These complexes were detected by mass spectrography, infrared, ultraviolet, and nucleus magnetic resonance. |
