An electronic system of infrared spectral data for toxicological analysis.
Abstract A large number of non-volatile poisons have been analyzed by infrared spectroscopy and spectral indices have been stored as standards. Comparison of the spectra of unknown samples with the standard spectra allows identification of the unknown samples. This comparison is carried out by computer.
Application of I.R. Spectrophotometry in Emergency Analyses
I.R. spectrophotometry has been applied in emergency toxicological analyses. Poisons and drugs are extracted into chloroform, potassium bromide is added to the extract and the solvent evaporated. Potassium bromide discs are prepared by compression and scanned in an I.R. spectrophotometer. A data bank of standard spectra has been prepared and computerized comparison of the spectral data of the sample extract with those of authentic compounds allows the identification of toxic agents in 'real time'.
PULSE: a high-repetition-rate linac driver for x-ray FELs
We describe a staged concept for a linac-based freeelectron laser providing coherent tuneable VUV and soft X-ray output with pulse lengths down to 10 fs or less. Use of 1.3 GHz cryomodules operated with CW RF will allow flexible pulse patterns at potentially very high repetition rates up to 1 MHz. We consider the options for FELs that may be included in a facility of this type.
