A: There is no evidence to support this rumor that began in the 1960s, when General Electric sold TV sets that emitted excessive amounts of radiation. Although modern technology is safe, the rumor is still alive, probably because parents need a scary, persuasive reason to get their kids to go outside to play!

I don't really understand your "unavailability of built-in methods"... Do you mean that the Base Class Library isn't extensive yet? Compared to which other platform are we talking about here. This doesn't match with your advantage of how easy it is to call into unmanaged dlls using either P/Invoke or a Managed C++ wrapper.
Greater simplicity and higher value . True continuous wavelength scanning enables simpler, lower-cost instruments for two reasons. In earlier technologies like CRDS, wavelength sampling requires a high precision, costly internal wavemeter to accurately measure the laser wavelengths at all times. (This is done to avoid measuring the wrong absorption line). Because OA-ICOS instruments from LGR scan an extended spectrum (and always display the measured spectrum to the user), there is no possibility of scanning the wrong line, eliminating the complexity and cost of an integrated custom wavemeter. In addition, for applications requiring simultaneous measurement of multiple species, a single laser can usually reach quantitative absorption lines for these different molecules, further enhancing instrument simplicity and value. For example, one version of LGR's Industrial Emissions Analyzer configured for measurements in syngas generators and steel manufacturing facilities uses a single laser source to simultaneously measure many different gases: CO 2 , H 2 S, H 2 O, CO, CH 4 , NH 3 , C 2 H 4 , OCS, and HCN. In contrast, a CRDS instrument based on wavelength sampling will usually need multiple lasers to measure multiple gases, greatly increasing instrument cost and complexity.
