Why should I want to analyse these samples
of copper ore in nitric acid solution on your
multichannel X-ray spectrometer, when
know that your sequential
automatic spectrometer already does it very well
''•jr
Answer: Because, in addition
to precision, you need maximum analysis speed - and the PW 1250
multi-channel spectrometer can reduce your analysis time per sample by 50%!
Not long ago, a leading industrial laboratory came to us with an interesting problem: "How does your new PW 1250 Multi-channel X-ray spectrometer compare in precision and speed with your already proven PW 1212, in the routine analysis of Cu, Zn, and Pb in solution?" Our Philips Application Laboratory was eager to demonstrate this. The results? Analytical results obtained from both instruments closely correlated with those obtained chemically. Using the ratio method,
total analysis times for the PW 1212 were 110 seconds per sample; for the PW 1250 multichannel spectrometer, 50 seconds per sample.
