C	3000.0000 (Minimum concentration detected)	193.0900	N/A	Univariate Calibration	3000.0000-7100.0000	The authors tried calibrations using the intensity in a single pixel of the C peak at 193nm [the 247.86nm peak had strong Fe interferences]. The pixel wavelengths were 192.78nm, 192.87nm, 192.96nm, 193.04nm and 193.15nm. Best results were obtained using a multivariate calibration against all 5 pixels.
