SURFACE-ENHANCED RAMAN SPECTROMETRY FOR DETECTION …

A schematic ,diagram, of a coupled HPLC-SERS ,system, is shown in Fig. 1. Spectra were obtained with a 0.22-m double-grating spectrometer (Spex Industries, model 1680B) with a 1200 grooves/mm classically ruled grating. The Raman scattering was collected at right-angles and detected with a cooled photo-

The SRS ,system, will provide protection during a frontal or oblique impact event. The ,system, will activate when the vehicle decelerates at a predetermined G force known to cause injury to the occupants. The cab and chassis will have been subjected, via third party test facility, to a crash impact during frontal and oblique impact testing.

The features of the sensor ,system, have a signal stability of 0.0596 % relative standard deviation (,RSD,) and repeatability of 10.35% ,RSD, when 80 ppm of standard Ca (II) is compared to a blank in the presence of 60 ppm of uric acid. The calcium sensor photoresistor shows a calibration curve of y=0.0001x-0.0023 with a limit of detection of 46.84 ppm.

These two chamber operate in series: The first piston is withdrawn slowly (taking about 4 seconds to withdraw 10 cm3 of fluids); the second piston is withdrawn at a faster rate, 5 seconds for 10 cm3.

Abstract: A pre-concentration ,system, (schematic ,diagram, given) was developed for flame AAS and applied to the determination of Pb in Cu metal, and Ag and Cd in geological samples. For determination of Ag and Cd in ore, sample (2 g) was digested with 10 mL of 1:1 aqua regia by heating, the solution was evaporated to ~5 ml, mixed with 0.5 mL of 1% gelatin before dilution with water to 10 mL.
